About this 0.63ct natural oval diamond

This 0.63ct natural oval sits in the half to three-quarter carat band, graded K colour (faint-tinted) 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 6551951599. Listed at 8 retailers as of November 4, 2026, with a 210% 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.
