Confidence

All rough and polished diamonds sold by our vendor comply with the Kimberley Process. The Kimberley Process ensures that rough diamonds are:
• Exported and imported with a government validated Kimberley Process certificate stating the diamonds are conflict-free.
• Transported between signatory countries in a sealed and tamper-proof container.
• Sold with a statement from the seller (known as a warranty) on all invoices guaranteeing that the diamonds being sold are conflict-free.

Security

Laser Engraved Identification
Our vendor laser engraves a unique number on the girdle of each Red Box Diamond®. This number matches the grading report, giving you proof positive identification. In addition, you can inscribe a custom message on the diamond for a nominal fee.
