About this 0.51ct natural emerald diamond

This 0.51ct natural emerald sits in the half to three-quarter carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 6565371108. Listed at 13 retailers as of November 3, 2026, with a 244% 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.
