About this 1.25ct natural round diamond

This 1.25ct natural round sits in the one-and-a-quarter to one-and-a-half carat band, graded M colour (faint-tinted) and SI2 clarity (slightly-included), with a top-tier cut grade and certified by IGI. Listed at 15 retailers as of November 5, 2026, with a 169% 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.
