MATERIALS & METALS

The foundation of every line we produce: precious metals and stones chosen for durability, quality and traceability. We work with gold, platinum, silver, diamonds and coloured gemstones, all sourced to our ethical standards. In our NYC Diamond District studio, we help partners choose materials that fit brand standards, target price and wear profile.

Precious Metals

We cast and finish in the metal of your choice. Each has distinct properties, aesthetics and care needs; we’ll guide you during your trade briefing so production matches your target look, weight and wear profile. For more on day-to-day care, see our Care Guide.

Gold

We work in 14K, 18K and 22K gold in yellow, white and rose. Karat indicates purity: 24K is pure gold (too soft for most jewellery), so 14K (about 58% gold), 18K (75%) and 22K (about 92%) balance durability with richness. 18K is a popular choice for production jewellery and fine pieces, it has a rich colour, holds up to daily wear and is still workable for detailed settings. 14K is harder and slightly more affordable; 22K is the softest we typically use and has a deep, buttery colour suited to certain designs.

Yellow gold is classic and warm. White gold is an alloy (often with nickel or palladium) and is usually rhodium-plated for a bright, silvery finish; the plating may need redoing every few years with heavy wear. Rose gold is an alloy with copper, giving a warm pink tone that has become a favourite for production jewellery and stacking pieces. We can also do two-tone or three-tone combinations (e.g. white and rose gold) for a single piece.

Platinum

Platinum is dense, hypoallergenic and holds up to daily wear. It’s ideal for production jewellery and pieces you’ll wear every day, it doesn’t tarnish and is more durable than gold in the sense that it loses less metal over time from wear. It develops a soft patina over the years that many clients love; others prefer a high shine, which we can restore with a polish. Platinum is typically more expensive than gold per gram because of its density and purity; we’ll outline cost implications when you’re choosing your design.

Silver

Sterling silver (925) is an option for pieces where you prefer a lighter metal or a different budget. It’s beautiful when polished but can tarnish with exposure to air and moisture; simple cleaning (see our Care Guide) keeps it looking its best. We can combine silver with gold accents for a two-tone look, or use it for pieces that are worn less often or for clients who want a striking design without the cost of full gold or platinum.

Diamonds & Gemstones

We source conflict-free diamonds, both natural and lab-grown, and coloured gemstones. Cut, clarity, colour and carat (the “four Cs”) can be discussed so your stone matches your design and budget. In the Diamond District, we have access to a wide range of stones; we’ll help you understand options without overwhelming you.

Diamonds

Whether natural or lab-grown, we select diamonds for cut quality (which drives brilliance), clarity and colour appropriate to the piece. For production jewellery, round brilliant and oval cuts are perennially popular; we also work with cushion, emerald, pear and other shapes. Fancy colours (e.g. yellow, pink) are available in both natural and lab-grown. Certificates (e.g. GIA, IGI) can be provided when we source certified stones.

Coloured Gemstones

Sapphires (blue and fancy colours) and rubies are durable and suit everyday wear. Emeralds are softer and more included by nature; they’re stunning but may need a bit more care. We also work with aquamarine, morganite, tourmaline, tanzanite and other stones. Origin and treatment (e.g. heated, unheated) can be discussed, we’ll be transparent about what you’re getting and how to care for it.

Recycled & Reclaimed Options

Recycled or reclaimed gold and platinum are available for clients who want to reduce the environmental footprint of their piece. The metal is refined to the same quality as newly mined material; the difference is provenance and impact. Ask us about options when you start your project, we’ll outline availability, lead time and any cost difference.

Care Considerations

Different metals and stones have different care needs. Gold and platinum are generally low-maintenance; silver may need occasional polishing; some gemstones are sensitive to heat, chemicals or knocks. We’ll give you specific guidance with your finished goods and you can always refer to our Care Guide or reach out for advice. For ongoing programmes, we stay available for materials questions across seasons.
