About this 0.8ct natural heart diamond

This 0.8ct natural heart sits in the just-under-one-carat band, graded D 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 6555152104. Listed at 5 retailers as of October 31, 2026, with a relatively tight 13% 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.
