About this 1.51ct natural oval diamond

This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded D colour (colourless) and I1 clarity (included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 3495805992. Listed at 10 retailers as of October 30, 2026, with a relatively tight 20% 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.
