About this 1.53ct natural heart diamond
This 1.53ct natural heart sits in the one-and-a-half to two carat band, graded H 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 6237866877. Listed at 9 retailers as of November 2, 2026, with a 69% 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.
