About this 0.9ct natural oval diamond

This 0.9ct natural oval sits in the just-under-one-carat band, graded J 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 1455106705. Listed at 5 retailers as of October 30, 2026, with a 75% 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.
