BEFORE YOU CHOOSE

Your questions. Clear answers.

How do I share a filtered search or a specific stone?

Use “Share search” in the catalogue or “Share” on a stone. The recipient opens the same criteria or offer. Price and availability are checked again on opening.

Are all stones physically in Sofia?

The catalogue provides access to international offers. Location and timing are checked for each stone before ordering; the catalogue count does not mean showroom stock.

How is a grading report checked?

We review the laboratory and report number for the individual stone and compare them with the specifications and available documents. A report is not a monetary appraisal.

Who operates DiamondTrade?

DiamondTrade is operated by Solaris Circle Ltd., company number 203809678, and is part of the Solaris Circle brand family. Meet us by appointment at Urban Model in Sofia.

How do I receive my order?

We use UPS. Preparation, delivery timing and applicable terms are confirmed for the specific stone and destination.
