About this 1.21ct lab-grown radiant diamond

This 1.21ct lab-grown radiant sits in the classic one-carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 1493873437. Listed at 7 retailers as of October 26, 2026, with a 449% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. Compare the cross-retailer prices above before buying. The same certified stone often varies 15 to 40% across stores.
