Coloured Gemstone Jewelry

VST crafts fine jewellery set with natural coloured gemstones, including emeralds, rubies, sapphires, tourmalines, amethyst, citrine, garnet, and more, across gold, silver, and platinum. Rooted in our founder’s own family history in emerald trading, our approach to colour goes beyond standard sourcing, shaping how every stone is selected, cut, and set.

Coloured gemstones are handled with the same flexibility we bring to design, cut in-house where precision demands it, or sourced already cut when the right stone calls for it. This gives us greater control over the final character of each gem, whether it’s a single statement piece or a fully coordinated set, and allows us to match the right approach to the right stone rather than following one fixed process.

Carving Techniques

Cabochon cutting, hand-carving, and relief carving, for stones with depth beyond a standard facet.

Colour Matching

Stones hand-matched for tone and clarity, so multi-piece sets read as one cohesive design.

Rare & Fancy Colours

Access to uncommon shades and less-available gemstones for distinctive collections.

Jewellery Styles

From cocktail rings and layered pendants to tennis bracelets and bridal suites.

Our coloured gemstone jewellery spans everyday fine pieces to high jewellery built for statement occasions, crafted in rings, earrings, necklace sets, pendants, chains, bracelets, bangles, and brooches, with colour leading every design decision. Each piece is built to work as part of a larger collection just as easily as it stands alone, giving buyers the freedom to scale a single design into a full range without losing its original character.
