About this 0.51ct natural oval diamond

This 0.51ct natural oval sits in the half to three-quarter carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 3445802867. Listed at 13 retailers as of November 4, 2026, with a 150% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. SI-grade stones are eye-clean roughly 60 to 70% of the time at this carat range. Check the inclusion plot on the cert and ask the retailer for high-resolution video before buying.
