About this 1.5ct natural heart diamond

This 1.5ct natural heart sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 6541519714. Listed at 25 retailers as of October 27, 2026, with a 85% 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.
