About this 1.33ct natural heart diamond

This 1.33ct natural heart sits in the one-and-a-quarter to one-and-a-half carat band, graded I 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. Listed at 4 retailers as of November 5, 2026, with a relatively tight 14% 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.
