Natural loose diamonds
Sourced through Hong Kong, one of the world’s leading diamond trading hubs, VST supplies natural, certified loose diamonds to retailers, manufacturers, and designers who set stones into their own collections. Every diamond is selected for cut precision, consistency, and certified authenticity, giving buyers a dependable stone for their own productions.
Colourless diamonds are our specialty, with expertise concentrated in the D-E-F colour range and VVS to VS2 clarity, the benchmark for exceptional diamonds. Each stone is evaluated against clear quality benchmarks before it’s offered, so what’s promised on paper matches what arrives, whether sourcing a single exceptional stone or matched parcels for a repeat production run.
Matched Calibrated Parcels
Diamonds sourced and matched for consistency across bulk or repeat orders.
Beyond round brilliants, we work across princess, emerald, oval, pear, marquise, cushion, radiant, asscher, heart, kite, trilliant, and baguette cuts. For designers with a specific vision in mind, we also accommodate custom cut requests, developed to match the exact proportions and design requirements you’re working with.
