Material Index
18K Gold Plated
18K Gold Plated jewellery is created by applying a layer of genuine 18K gold over a base metal. The quality and longevity of gold-plated jewellery depend greatly on the material beneath the gold layer.
BY TONIN 18K Gold Plated pieces are crafted with a premium 925 Sterling Silver foundation, finished with a minimum 1-micron layer of genuine 18K gold and enhanced with a protective nano-ceramic coating. Unlike many standard gold-plated pieces that use non-precious base metals, our Sterling Silver foundation provides a higher-quality, more refined jewellery experience.
Our considered plating process delivers the warmth and beauty of 18K gold while maintaining the value and integrity of a precious metal base. Unlike standard “flash” plating, which may measure only 0.1–0.5 microns, our thicker gold layer and protective coating provide improved resistance to everyday wear, helping your jewellery maintain its finish for longer.
Designed for effortless styling and everyday elegance, BY TONIN 18K Gold Plated jewellery offers an accessible way to enjoy the beauty of gold with the quality of genuine Sterling Silver beneath.

What is 18K Gold Plated jewellery?
18K Gold Plated jewellery is made by applying a layer of genuine 18K gold over a Sterling Silver base. It offers the appearance of gold while providing a more accessible alternative to solid gold jewellery.
Is 18K Gold Plated better than standard gold plating?
Yes. BY TONIN 18K Gold Plated jewellery uses a Sterling Silver foundation and a thicker gold layer than standard flash plating. The added nano-ceramic protective coating helps improve resistance to everyday wear.
How long does 18K Gold Plated jewellery last?
The lifespan depends on the thickness of the gold layer, frequency of wear, and care routine. With proper maintenance, it can maintain its appearance for years.
Can 18K Gold Plated jewellery be worn every day?
Yes, especially earrings and necklaces. For high-contact pieces such as rings and bracelets, additional care is recommended to minimise friction and extend the life of the gold finish.
Does 18K Gold Plated jewellery tarnish?
The gold surface helps protect the Sterling Silver underneath, but over time the finish may naturally change with wear. Proper care helps maintain its colour and shine.
Can 18K Gold Plated jewellery become an heirloom?
Yes, it can become a meaningful keepsake. While the gold layer may eventually wear with time, the foundation remains genuine 925 Sterling Silver, a precious metal that can be valued, maintained, and cared for. Unlike plated jewellery made over base metals, Gold Plated Sterling Silver retains a precious metal foundation.
Sterling Silver
Sterling Silver is a precious metal alloy made from 92.5% pure silver and 7.5% alloy metals, most commonly copper. Pure silver is naturally soft, so alloying it improves strength, durability, and suitability for everyday jewellery while maintaining its bright white lustre.
Our 925 sterling silver is chosen for its durability and natural finish. Whenever possible, we use recycled silver as part of our commitment to responsible production. Simple and versatile, our sterling silver pieces are a thoughtful choice for those who value high-quality jewellery designed to be worn for years.
Sterling Silver offers timeless appeal, exceptional versatility, and can be polished, repaired, and refinished throughout its lifetime.
The silver content is measured by its purity:
Fine Silver — 99.9% pure silver (too soft for most jewellery)
Sterling Silver (925) — 92.5% silver, 7.5% alloy metals
Sterling Silver is valued for its brilliant finish, precious metal content, affordability, and ability to last for decades with proper care.

Material category: Precious metal
Positioning: Premium accessible luxury
Sterling Silver (925) is recognised worldwide as a genuine precious metal and is one of the most popular materials used in fine jewellery. It offers the quality and longevity of a precious metal at a more accessible price point than gold or platinum, making it an ideal choice for everyday luxury.
Compared with fashion jewellery made from plated base metals, Sterling Silver offers greater longevity, can be professionally repaired and refinished, and retains intrinsic precious metal value. While it does not typically hold the same investment value as high-karat gold or platinum, it is highly regarded for its craftsmanship, versatility, and enduring appeal.
Mohs hardness is a scale that measures how resistant a material is to being scratched.
Typical ranges are:
- Fine Silver (99.9%): ~2.5–3 Mohs
- Sterling Silver (925): ~2.5–3 Mohs
Although Sterling Silver is harder than pure silver, it remains a relatively soft precious metal compared to stainless steel or titanium. This softness allows jewellers to create intricate designs while also making the metal easier to resize, repair, and polish.
Hardness measures scratch resistance, not strength. Sterling Silver may develop fine surface scratches with everyday wear, but these can usually be polished away, helping restore the jewellery's original finish.

While it may develop scratches or tarnish with regular wear, these are typically surface changes that can be removed, allowing well-crafted Sterling Silver pieces to become meaningful heirlooms passed down through families.
- Does Sterling Silver tarnish?
Yes. Sterling Silver naturally tarnishes over time as it reacts with sulphur in the air. Tarnish is a surface layer only and can be removed through cleaning or polishing.
- Is Sterling Silver real silver?
Yes. Sterling Silver is genuine precious metal containing 92.5% pure silver, which is why it is commonly stamped "925."
- Can Sterling Silver be worn every day?
Yes. Sterling Silver is suitable for everyday wear. With regular cleaning and proper storage, it can maintain its appearance for many years.
- Is Sterling Silver hypoallergenic?
Sterling Silver is generally well tolerated by most people. However, individuals with sensitivities to certain alloy metals should check the composition before purchasing.
Gold Vermeil
Gold Vermeil (pronounced as ver-may) is a premium jewellery finish made by coating a solid Sterling Silver base with a thick layer of genuine 18K gold. Unlike standard gold plating, Gold Vermeil must meet recognised industry standards, using Sterling Silver as the base metal and a substantially thicker layer of gold.
BY TONIN 18K Gold Vermeil pieces are crafted from solid 925 Sterling Silver and finished with a generous 2.5-micron layer of genuine 18K gold. This creates the luxurious warmth and appearance of solid gold while offering a lighter, more accessible alternative for everyday wear.

Unlike gold-plated jewellery made over base metals, Gold Vermeil does not reveal a non-precious material beneath the gold layer. With professional care, including potential re-plating when desired, well-crafted Gold Vermeil pieces can continue to be enjoyed and passed down as sentimental jewellery for generations.
Solid Gold
Solid Gold is a precious metal made from genuine gold throughout the entire piece, rather than being plated or coated over another material.
BY TONIN 9K Solid Gold pieces are designed to be worn , loved and treasured for years to come. Solid gold will not wear away or reveal a base metal over time. Its durability makes it ideal for daily wear, while its timeless appeal ensures it remains a staple in your collection for generations.
Because pure gold is naturally soft, jewellery gold is usually alloyed with other metals such as silver, copper, zinc, or palladium to improve strength, colour, and durability. The gold content is measured in karats:
- 9K Gold — 37.5% gold
- 14K Gold — 58.5% gold
- 18K Gold — 75% gold
- 22K Gold — approximately 91.6% gold
- 24K Gold — 99.9% pure gold
Solid gold is valued for its lasting beauty, corrosion resistance, rarity, and ability to be repaired, polished, and passed down through generations.

Mohs hardness is a scale that measures how resistant a material is to being scratched.
Typical ranges are:
- 24K gold (99.9% pure): ~2.5–3 Mohs
- 22K gold: ~2.5–3 Mohs
- 18K gold: ~3–4 Mohs
- 14K gold: ~3.5–4 Mohs
- 9K gold: ~3–4 Mohs (can vary depending on the alloy)
The reason is that pure gold is very soft and malleable. Jewellers mix it with harder metals such as copper, silver, nickel, or palladium to make it more durable. Generally:
- Higher karat = more gold = softer.
- Lower karat = less gold, more alloy metals = harder and more scratch-resistant.
It's also worth noting that hardness (resistance to scratching) is different from toughness (resistance to breaking or bending). Gold is soft enough to scratch relatively easily, but it is also very tough and doesn't shatter.
High when selected for the intended use.
Strengths:
- Does not rust or corrode
- Maintains colour permanently
- Can be repaired, resized, and refinished
- Suitable for heirloom jewellery
Considerations:
- Softer than many alternative metals
- Higher-purity gold scratches more easily
- Rings and high-contact pieces may develop surface marks over time
Lower-karat gold is generally harder, while higher-karat gold offers a richer colour and higher precious metal content.
- Clean with warm water, mild soap, and a soft cloth
- Avoid exposure to harsh chemicals, chlorine, and abrasive materials
- Store separately to prevent surface scratches
- Remove jewellery during activities that may cause impact or abrasion
- Have regularly worn pieces professionally checked and polished when needed
- Avoid ultrasonic cleaning for delicate pieces or jewellery containing sensitive gemstones
- What does solid gold mean?
Solid gold means the jewellery is made from gold alloy throughout the entire piece. It is not gold plated or gold filled.
- Does solid gold tarnish?
Pure gold does not tarnish. Some alloy metals mixed with gold may react slightly depending on the composition and environment.
- Is solid gold better than gold plated?
Solid gold is more durable, retains value, and can be repaired and refinished. Gold plating is a surface layer that can wear away over time.
- Which gold purity is best for everyday jewellery?
18K and 14K gold are popular choices because they balance gold content, colour, and durability. Lower karat gold is also commonly used where greater affordability and strength are priorities.
- Can solid gold be worn every day?
Yes. Solid gold is suitable for daily wear when the correct karat and design are chosen.
- Does solid gold hold its value?
Gold has intrinsic value based on its weight and purity. Higher-karat gold generally contains more precious metal.

Mohs hardness is a scale that measures how resistant a material is to being scratched.
Natural White Topaz: 8 Mohs
White Topaz is a durable gemstone and ranks 8 on the Mohs hardness scale, making it suitable for everyday jewellery. It is harder than many commonly used gemstones and offers excellent resistance to surface scratching.
However, hardness does not mean complete resistance to damage. Like all gemstones, White Topaz can chip or fracture if exposed to strong impact, especially around sharp edges or delicate settings.
High when properly cared for.

Common questions
The 4C's Diamond Guide
A diamond’s beauty and value are defined by the 4C’s: Cut, Colour, Clarity, and Carat. At BY TONIN, our strict selection process ensures every stone possesses an extraordinary balance of these elements, delivering uncompromising quality and maximum brilliance.
Cut: The Measure of Brilliance
Often considered the most crucial characteristic, the cut dictates how a diamond interacts with light. A masterfully cut diamond reflects light from one facet to another and seamlessly back up through the top. Poorly cut stones will appear flat and lifeless. BY TONIN selectively curates 'Excellent' and 'Ideal' cuts to ensure breathtaking fire.
Cut F.A.Q
Why is cut considered the most important of the 4C's?
What cut grades does BY TONIN offer?
How does a premium cut perform in natural light?
Colour: Purity & Whiteness
Diamond colour is graded by the absence of colour. The scale begins at 'D' (colourless) and extends to 'Z' (light yellow). The closer a stone is to colourless, the rarer it becomes. BY TONIN stones are exclusively selected from the Colourless (D-F) to premium Near-Colourless (G-H) ranges, guaranteeing a pristine aesthetic.
Colour F.A.Q
What is the best diamond colour?
Are these colour grades standard for everyday jewellery?
What metals pair best with colourless diamonds?
Clarity: Unblemished Perfection
Created under immense pressure, diamonds possess tiny trace characteristics called inclusions. Clarity grades evaluate the size and position of these under 10x magnification. At BY TONIN, we exclusively curate VVS (Very, Very Slightly Included) grades, ensuring your stone is exceptionally pure and inherently eye-flawless.
Clarity F.A.Q
What does "Eye-Clean" mean?
Are lab-grown diamonds flawless?
Do you ship VVS diamonds across New Zealand?
Carat: Weight & Proportion
Carat is a measurement of weight, not physical size. Because larger diamonds are found less frequently, value increases exponentially with carat weight. However, a high-carat diamond with a poor cut will look smaller than a perfectly cut stone of lower weight.
Carat F.A.Q
Does a higher carat mean a larger diamond?
What is the minimum carat weight BY TONIN offers?
Is a 1.00 carat diamond the standard size in NZ?

Frequently Asked Questions
Why do you use a Sterling Silver base instead of Brass?
We believe that what lies beneath the surface is as important as the finish. While many brands use brass or bronze to reduce costs, these base metals are reactive and often lead to skin discolouration or irritation. By exclusively using solid 925 Sterling Silver, we ensure every piece is a precious metal at its core, offering inherent value, skin safety, and a more refined weight.
What is a Nano-Ceramic coating and why is it important?
The most common frustration with gold-plated jewellery is the speed at which it wears. To combat this, we apply an invisible, medical-grade Nano-Ceramic seal over our 18k gold layers. This advanced technology creates a transparent shield that increases resistance to daily friction, salt air, and oxidisation, significantly extending the life and lustre of the golden finish.
Learn more about it here.
Will my jewellery turn my skin green?
No. Skin discolouration is typically caused by base metals like brass, copper, or nickel reacting with your skin’s natural oils. Because BY TONIN jewellery is crafted from 100% nickel-free 925 Sterling Silver and layered with high-carat gold, it will not react with your skin or cause "greening," making it a dependable choice for everyday wear.
What does the "925" hallmark mean?
The "925" stamp is a guarantee of purity, signifying that your jewellery is made of 92.5% pure silver and 7.5% alloy for strength. This is the global standard for high-quality silver jewellery. At BY TONIN, we uphold this standard across our entire collection, providing you with the assurance of genuine precious metal.
Is demi-fine jewellery worth the investment?
Demi-fine jewellery offers the perfect balance of luxury and value. Unlike "flash-plated" fashion pieces that tarnish within weeks, our demi-fine standard utilises a thick 18k gold layer (1.0 to 2.5 microns) over solid silver. When combined with our protective nano-ceramic seal, these pieces offer a longevity that far exceeds their price point, making them a conscious investment for a permanent wardrobe.
Which is better for daily wear: Gold Vermeil or Gold Plated?
Both standards represent a significant leap in quality over fashion jewellery, though the choice depends on your lifestyle and how you wear your pieces.
Gold Vermeil (2.5 microns) is utilised in our ring collections. Because rings encounter the most physical contact, our Vermeil pieces provide a substantial gold layer that offers the weight, prestige, and deep lustre of solid gold. It is the ideal choice for statement pieces and investment rings intended for "last on, first off" wear.
Our Gold Plated pieces (1.0 micron) are specifically engineered for high-cadence daily wear and "high-touch" environments.
Both Gold Plated and Gold Vermeil options feature an innovative nano-ceramic coating, an invisible shield that provides extra resistance against friction, salt air, and the natural oils of the skin. This makes our range exceptionally durable for delicate everyday chains and earrings that stay on from morning to night.
