Extended Collection

We use recent inventory with distinct stock references, a supported grading lab and usable measurements, then look for the same shape, grading lab, color and clarity, with closely matching weight and measurements. Any supplied cut, polish, symmetry, fluorescence, growth and treatment details must also match.

Report links appear when report numbers are available. Otherwise the cards say “Reports to be confirmed”; we must obtain and verify the reports before confirming the pair. A suggested pair is not a certified match.

Weight differs by no more than 0.05 ct and 3%; face-up dimensions by no more than 0.15 mm and 2%; length-to-width ratio by no more than 0.03; depth by no more than 0.15 mm and 3%. These are our selection guidelines. Individual grading reports do not certify the two stones as a matched pair.

Suggestions are a selection of close matches, not every possible combination. Photos, fluorescence and how the stones look together still need review. You can also compare any two individual diamonds.
