About this 3.03ct natural heart diamond

This 3.03ct natural heart sits in the three to five 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 1229970594. Listed at 2 retailers as of November 6, 2026, with a relatively tight 7% 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.
