About this 1.2ct natural oval diamond

This 1.2ct natural oval sits in the classic one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 6542557206. Listed at 15 retailers as of November 6, 2026, with a relatively tight 18% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
