The metal a piece of jewellery is made from determines how it wears, how it ages, and what it costs over time. It is one of the most consequential decisions in buying fine jewellery, and one that is often made with less information than it deserves. This guide covers the three metals DHARIN works with — 14K solid gold, 18K gold vermeil, and S925 silver — and the practical differences between them.
S925 Silver
S925 silver — also called sterling silver — is an alloy of 92.5% pure silver and 7.5% other metals, typically copper. The 925 hallmark refers to this ratio: 925 parts per thousand pure silver. Pure silver (999) is too soft for jewellery use; the copper content adds the hardness needed for settings, links, and fine details to hold their form under daily wear.
Silver has the highest reflectivity of any metal — higher than gold, higher than platinum. A well-polished silver piece has a cooler, brighter white than white gold, which has a slightly warmer tone even after rhodium plating. This makes silver particularly effective as a setting for colourless diamonds and for blue sapphires, where the cool metal amplifies the stone’s depth.
The practical consideration with sterling silver is tarnish. Silver reacts with sulphur compounds in the air and on skin, forming silver sulphide — a dark grey or black surface layer. The rate of tarnish varies with environment, skin chemistry, and how frequently the piece is worn and cleaned. Pieces worn daily tarnish more slowly than those stored unworn; skin contact and regular polishing both slow the process.
Tarnish is surface-only and fully reversible. A silver polishing cloth or a brief soak in warm water with mild dish soap restores the original finish. Sterling silver is not damaged by tarnish; it is a cosmetic change, not a structural one. Pieces stored in anti-tarnish pouches or airtight bags tarnish significantly more slowly.
DHARIN in S925 silver — the entry point to the collection. The Floating Bezel Diamond Pendant starts at $149, the Diamond Solitaire Studs from $198, the Pavé Eternity Band from $199. Coloured stone pieces — the Sapphire Halo Studs, Emerald Halo Studs, and Ruby Halo Studs from $168, and the Sapphire, Emerald, and Ruby Tennis Bracelets from $349. All with IGI-certified cultivated stones in the same specifications as higher metal tiers.
18K Gold Vermeil
Vermeil (pronounced ver-MAY) is a specific category of gold-plated jewellery with defined standards: a sterling silver base (S925) with a gold layer of at least 2.5 microns thickness, applied through electroplating. The gold layer must be at least 10K; DHARIN uses 18K gold, which means the plating layer is 75% pure gold.
The distinction between vermeil and standard gold-plated jewellery is significant. Standard gold plating can be applied over any base metal — brass, copper, or zinc alloy — and at any thickness, sometimes as thin as 0.5 microns. Vermeil requires a silver base and a minimum plating depth that provides meaningfully longer-lasting coverage. A 2.5 micron 18K vermeil layer over S925 silver is a fine jewellery product. A 0.5 micron gold flash over brass is costume jewellery, regardless of how it is marketed.
The warm yellow of 18K gold is one of the most versatile tones in fine jewellery. Against diamonds, it produces a warmer brilliance than white metal settings. Against cultivated sapphire, the contrast between deep blue and warm gold is one of the most historically resonant combinations in jewellery — present from ancient Egypt through the British royal collection to contemporary design.
The practical consideration with vermeil is wear. Gold plating will eventually wear through at points of friction — the inside of ring bands, bracelet clasps, areas where a necklace chain rests against the collarbone. At 2.5 microns minimum, quality vermeil can maintain its appearance for one to three years of daily wear before showing wear-through at high-friction points. Vermeil should not be worn in swimming pools, in the shower with sulphate-containing products, or while applying perfume or hand cream directly to the piece.
DHARIN in 18K vermeil — the warmth of gold at a mid-tier price point. The Classic Diamond Tennis Bracelet from $599, the Diamond Tennis Necklace from $599, the Diamond Station Necklace from $349, and the Diamond Pavé Huggie Earrings from $259. The Sapphire Halo Ring, Ruby Halo Ring, and Emerald Halo Ring are all available from $449 in 18K vermeil. The full necklace and earring collection is available in this tier.
14K Solid Gold
14K solid gold is an alloy that is 58.3% pure gold (14 parts per 24) throughout the full thickness of the metal. There is no base layer and no plating; the composition is consistent from surface to core. The remaining 41.7% is typically a combination of silver, copper, zinc, and palladium, with the precise ratio determining the final colour: yellow gold, white gold, or rose gold.
14K is the standard for fine jewellery in the United States and much of the English-speaking market. It is harder and more durable than 18K gold (which is 75% pure and therefore softer), while retaining the warm colour and corrosion resistance that make gold the defining precious metal for fine jewellery.
Solid gold does not tarnish, does not wear through, and does not require replating. A 14K solid gold piece worn daily for twenty years will show wear on its surface in the form of fine scratches and a softening of sharp edges — a patina that most wearers consider part of the piece’s character rather than damage. The metal itself is not degraded. This is the fundamental difference between solid gold and any plated or vermeil product: the material is permanent.
14K solid gold can be polished back to its original finish by any jeweller. Settings can be re-tipped and clasps repaired. The piece can be resized, modified, and passed on. It is the only metal in this category that is genuinely multi-generational.
DHARIN in 14K solid gold — the permanent tier. The Oval Solitaire Ring from $699 in 14K white, yellow, or rose gold. The Classic Diamond Tennis Bracelet from $899 in 14K white gold, up to $1,999 for the upgraded stone specification. The Mixed-Cut Tennis Bracelet from $999 in 14K white or yellow gold. The Diamond Tennis Necklace from $899 in 14K white gold. The Diamond Pavé Huggies from $399 and Floating Bezel Pendant from $399 in 14K solid gold. Pieces in this tier are built to be worn daily, indefinitely.
How to choose
The decision depends on three things: how frequently the piece will be worn, what budget makes sense, and what the piece means to the person who will wear it.
S925 silver is the right choice when the priority is maximising stone quality within a budget, when the design is the focus rather than the metal, or when the piece will be worn occasionally rather than daily. It is also the natural choice for anyone who prefers cool-toned metal — silver’s brighter, crisper finish suits certain designs and skin tones more than white gold. The Sapphire Halo Studs, Ruby Halo Studs, and the full coloured stone tennis bracelet range in silver deliver IGI-certified cultivated stones at the most accessible price points in the collection.
18K vermeil is the right choice when the warmth of gold matters aesthetically but daily-wear permanence is not the primary concern, or when budget sits between silver and solid gold. It is also the best option for pieces worn for specific occasions rather than continuously — a necklace or halo ring worn several times a week will maintain its vermeil finish significantly longer than one worn and slept in every day. The Tennis Necklace and Diamond Station Necklace in 18K vermeil bring gold warmth to layering combinations at a price point that makes the full three-necklace stack accessible.
14K solid gold is the right choice for any piece intended for continuous daily wear without removal — particularly rings and bracelets, which are subject to the most friction. It is also the right choice when the piece carries personal significance that warrants a permanent material: an engagement ring, a bracelet given to mark a particular moment, a pair of studs worn every day for years. The Oval Solitaire Ring and Classic Diamond Tennis Bracelet in 14K white gold are the two pieces in the DHARIN collection most often chosen for this reason.
All three metals carry the same IGI-certified lab-grown diamonds and cultivated gemstones. The stone specifications do not change between tiers. What changes is the permanence of the metal surrounding them — and what the piece will look like in ten years.
