About this 1.05ct natural radiant diamond

This 1.05ct natural radiant sits in the classic one-carat band, graded H 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 1455398618. Listed at 8 retailers as of October 31, 2026, with a 44% 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.
