Unheated sapphire, unheated blue sapphire, fancy colored sapphire, rubies, and large gems. See gemstones differently. Bespoke jewelry design services.
Our selection is very precise, small but coveted. We are not gem dealers. What you see here is a selection of a selection of a selection!
We offer mostly unheated gems for sale. Many are at least 5 carat, meaning they are regarded as investment gems if they satisfy gemological criteria.
We consistently select our gemstones thinking, how will an imaginative mind set this into a memorable piece of jewellery? Before we include a stone for sale here, we always know how we’d like to set it.
We are an ideal choice if you are looking for an interesting stone, and a setting intuitive to that stone.
We curate only natural stones. Every design is built by hand.
We are not really gem dealers or jewellers in the traditional sense.
We work with a small group of gem collectors who are sometimes ready to part with bits of their collection, to “quiet types” like us.
This is why we are able to offer large gems at good prices, and why our collection is small but broad.
