Lab-grown diamond and IGI report

This is a lab-grown diamond, not moissanite or cubic zirconia. It is a diamond created in a laboratory rather than mined. Each purchased stone includes its individual IGI report. The report relates to the purchased stone; no example report number or grading certificate is used on this page.

Planning your jewellery

Choose a loose cushion diamond for a custom ring, pendant or another jewellery project. Have your jeweller confirm the individual stone’s measurements and setting requirements before preparing a mounting. Specific dimensions, cut grades, polish and symmetry grades are not promised by this listing.

Processing and care

Allow 4–7 business days for processing before dispatch. Delivery transit time is additional; destination-specific delivery information is shown at checkout. Handle the loose stone carefully, store separately from other jewellery and have it set by a qualified jeweller.
