About this 1.7ct natural heart diamond

This 1.7ct natural heart sits in the one-and-a-half to two carat band, graded F 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 2556023485. Listed at 16 retailers as of October 31, 2026, with a relatively tight 8% 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.
