Looking for a loose antique diamond?

Cut descriptions follow the individual catalogue records. If you are seeking a diamond from a particular historical period, ask what evidence supports the age of that stone. A laboratory grading report and a cutting-style name serve different purposes in that discussion.

Listed diamonds and public asking prices

Prices are in US dollars for loose diamonds. Confirm availability and a written quotation before inspection or payment. Tell us if your budget includes a finished ring or other piece of jewellery so that the stone and setting can be considered together.

Build a selection around your intended use

For an engagement ring, begin with the outline and millimetre dimensions you want on the hand, then compare colour, clarity, condition and the movement of the facets. For an existing setting, provide its measurements and photographs before selecting a stone.

A larger loose diamond may need a different setting design or inspection plan from a smaller stone. Send the references that interest you and the questions you want answered. We can discuss additional photographs, report details and viewing options for each diamond.

Buying from another country

Start with your destination and the stone reference. Inspection may be arranged by prior agreement at our office, through an agreed independent professional, at a trusted partner office or through an available secure facility. Location, custody, costs and the payment sequence are confirmed before the stone moves.

Insured shipping is included with a completed purchase. Inspection-only logistics, return conditions, taxes, duties and identity checks are discussed for the individual transaction. Read the inspection and international buying questions before arranging a viewing.
