About this 1.51ct natural oval diamond

This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 2557636242. Listed at 20 retailers as of November 5, 2026, with a 134% 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.
