VST specialises in natural diamonds and natural coloured gemstones, offering bespoke design and private-label manufacturing in gold, silver, and platinum.

 Production takes place across our houses in Hong Kong, China, and India, with each stage shaped by quality checks and meticulous finishing.

Our MOQs are shaped by design complexity and stone usage rather than a fixed volume, so smaller businesses and boutique brands can start with realistic order sizes alongside larger production runs.

 Our services include design consultation, custom design, gemstone sourcing, and private-label manufacturing, covering OEM, ODM, white-label, and contract manufacturing. Our in-house design team also supports clients from original concept through CAD modelling, sampling, gemstone finalisation, and production-ready designs.
