What we deal in
Sapphire is our principal specialism. We also supply ruby, emerald, spessartite, aquamarine and tourmaline, as individual stones and to specification.

What you see online is
a fraction of what
we can find.
Most of what Giri supplies never appears on a website. It moves between people who have worked together for years.
Tell us the stone, colour, size, shape, quality, quantity and timing. We will confirm what we can offer and the expected next steps.
Calibrated and matched stones
Calibrated and matched stones for jewellery production. Tell us the gem, colour, shape, dimensions, quantity and timing; we will confirm suitable material and matching options.
Photographs illustrate our range. Contact us to discuss viewing the full parcel; current stock, sizes and matching are confirmed by enquiry.
For repeat orders, send the original reference or a sample so we can assess the match.
Suites, ready to set
Matched calibrated stones laid out as a finished design, so a manufacturer or designer can see the piece before it exists. Each layout can be bought complete.
