About this 0.3ct natural marquise diamond

This 0.3ct natural marquise sits in the sub-half-carat band, graded I colour (near-colourless) and I1 clarity (included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 1488051289. Listed at 2 retailers as of November 2, 2026, with a relatively tight 0% spread, which is unusual at this carat range and suggests competitive pricing across the listings. Compare the cross-retailer prices above before buying. The same certified stone often varies 15 to 40% across stores.
