About this 1.01ct natural heart diamond

This 1.01ct natural heart sits in the classic 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 6541330129. Listed at 21 retailers as of October 28, 2026, with a 157% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
