About this 0.91ct natural oval diamond

This 0.91ct natural oval sits in the just-under-one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 1553104112. Listed at 12 retailers as of October 29, 2026, with a 91% 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.
