Eligibility of Client-Supplied Gemstones
For purposes of our Client-Supplied Gemstone Policy, an heirloom is defined as follows: “A valuable object owned by a family for many years and passed from generation to generation.”
Leon Mege Inc. may, at its sole discretion, accept an heirloom gemstone for incorporation into a new custom jewelry piece. However, not all client-owned gemstones are eligible for use in Leon Mege jewelry. Without limiting our discretion, a client-owned gemstone may be deemed ineligible if:
- Leon Mege Inc. previously assisted, advised, sourced, or communicated with the customer about acquiring a gemstone before the customer purchased it or a different stone from another source.
- The customer cannot provide satisfactory documentation establishing lawful ownership and purchase from a legitimate, verifiable source.
- Leon Mege Inc. reasonably believes the gemstone may have been imported, transferred, or routed through intermediaries to circumvent applicable United States laws, regulations, sanctions, trade restrictions, or import requirements.
- The gemstone was acquired by the customer within thirty (30) days preceding the initial contact with us.
- The gemstone’s most recent grading report, laboratory certificate, or comparable gemological documentation was issued less than six (6) months before contacting Leon Mege Inc.
- The gemstone is laboratory-grown, synthetic, imitation, assembled, coated, fracture-filled, glass-filled, plastic-filled, treated in a manner that materially affects durability, or otherwise not appropriate for use in fine bespoke jewelry.
- The gemstone exhibits damage, structural instability, excessive wear, durability concerns, undisclosed treatments, authenticity concerns, or any other condition that, in Leon Mege Inc.’s judgment, makes it unsuitable for the intended design.
Acceptance of any client-supplied gemstone remains subject to inspection, authentication, technical evaluation, and final approval by Leon Mege Inc. Submission of a gemstone for review does not create any obligation on the part of Leon Mege Inc. to accept the stone or undertake the proposed project.

We source better diamonds at a better price
To create a beautiful piece of jewelry, you start with the most beautiful stone.

Proof of origin required
We require a written statement confirming that the stone does not originate in any country subject to U.S. government sanctions before we can 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, which regulates the rough diamond trade and prevents 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 a ban on importing Burmese-origin jadeite and rubies and any jewelry containing them. Unfortunately, the Obama Administration revoked it on October 7, 2016, under Executive Order 13742.
