Estate diamond jewelry and individual stones

Estate jewelry can offer designs and construction that are difficult to reproduce in a standard catalog. Review the entire piece—including the setting, condition, and documented stone details—not only a headline carat weight.

Reports and documentation when present

An independent grading report can document characteristics of a submitted stone, but not every estate diamond or gemstone arrives with one. Product listings should identify included documentation when it is available; ask us about a specific piece when details are unclear.

See color and character in person

Lighting, neighboring colors, cut, and setting style all affect how a diamond or colored gemstone appears. Viewing an available piece in person can help you judge those characteristics in context.

About Diamonds & Gemstones

We describe stones as they present in the piece — approximate carat weight, colour, and clarity where we can assess them — and we say when a measurement is an estimate rather than a laboratory grade. When a piece comes with a GIA or other laboratory report, the report is included with the piece and the listing says so.

Frequently asked questions

Some do. Estate pieces come to us the way their previous owner kept them, so a laboratory report is present on some and not on others. When a report exists it is included with the piece and referenced in the listing. When there is none, we say so plainly and describe the stone from our own inspection rather than implying a grade we have not had verified.
