Heirloom stones

We supply all diamonds and gemstones because they have a massive impact on the look of a ring. We can design and make a new piece using a stone you inherited. However, we will not set a stone recently purchased elsewhere. Some exclusive designs, including “Cosmo,” “MonCheri,” “Cold Fusion,” and “Lotus,” can only be made with our stones.

Merriam-Webster's definition of an heirloom

“A valuable object owned by a family for many years and passed from generation to generation.”

We will not consider a diamond or a gemstone an heirloom when:

  • you bought the stone after contacting us first
  • the stone was purchased less than a month ago
  • the stone’s certificate was issued less than six months ago

Glass/plastic-filled, coated, or structurally unstable gemstones are not acceptable.

It should be carefully selected to be suitable for the intended design. To help you find, select, and acquire a perfect stone, we cultivate close relationships with the best diamond companies in the world.

Proof of origin required

We require a written statement confirming that the stone does not originate in any country under the sanctions by the US government to accept an heirloom stone for work.

The stone must conform to the Kimberley Process established in 2003 by 48 individual states and the 27-member European Union regulating rough diamond trade and preventing the flow of conflict diamonds.
The stone must conform to the Imposition of Sanctions on `Luxury Goods’ Destined for Russia and Belarus and for Russian and Belarusian Oligarchs and Malign Actors Under the Export Administration Regulations (EAR) – Document 2022-05604 Rule 87 FR 14785 CFR: 15 CFR 738 15 CFR 746 Docket No. 220311-0071 RIN: 0694-AI78
The sanctions imposed by the United States on Burma (Myanmar) in response to the Burma military regime’s atrocities included the ban on importing Burmese-origin jadeite and rubies and any jewelry containing them. Unfortunately, it was revoked on October 7, 2016, with Executive Order 13742, by the Obama Administration.

We respectfully decline a commission from those who were shopping with us but purchased elsewhere. We respect our colleagues who have previously worked with you and sold you the stone.
