Triangular Cut Gemstones

Every stone held by the house, listed one at a time.

What makes a gemstone unforgettable? Sometimes, it’s the angle.
The Triangular Cut Gemstones collection features rare natural gemstones shaped with precision and bold geometry. Chosen by collectors who seek something distinct, each stone is selected for its color, clarity, and character. No two are the same — making every piece a unique starting point for a bespoke ring, pendant, or heirloom design.

Your story doesn’t have to follow a straight line. Neither should your gemstone.

Colour comes first The beauty of a gemstone begins with colour. Tone, saturation, and character often shape value more than size alone.
The report matters Independent laboratories help clarify what a stone is, and how it should be understood before it is chosen.
Treatment should be stated Many gemstones are treated in accepted ways. What matters is that it is disclosed honestly, before you buy.

Questions, Answered

An unheated gemstone has not been treated with heat to improve its colour or clarity. In stones such as ruby and sapphire, this is uncommon and often more highly valued. Where a stone is unheated, we state it clearly.

We work with recognised laboratories including GIA, GUILD, AIGS, CGRL, GRS, and GRC. Where a stone carries a report, it is shown clearly on the listing.

Yes. If you would like a gemstone sent to a different laboratory for review, we can arrange this on your behalf. The external laboratory fee is paid at cost.

Yes. Every loose gemstone can remain loose, or be made into a finished jewel through our bespoke process. We can create rings, pendants, necklaces, bracelets, or earrings around the stone.

Every gemstone is shipped fully insured, together with its report where applicable. Complimentary insured shipping is included.

Only part of our sourcing world is shown online. If you have a specific gemstone in mind, tell us the size, colour, shape, origin, or budget, and we will source options privately for you.
