Gemstone Options

Our diamonds and coloured gemstones are grown in a controlled lab environment, chemically and optically identical to their mined counterparts.

For a full breakdown of what each specification means and why it matters, see Our Standards.

Lab-grown coloured stones

IGI certification is available for coloured stones on request. Additional cost and lead time may apply - contact support@heirest.com for details.

Every piece is accompanied by a HEIREST Statement of Authenticity confirming your stone specifications and metal details.
