About this 1.51ct natural round diamond

This 1.51ct natural round 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 and certified by GIA 6532186971. Listed at 19 retailers as of October 22, 2026, with a 53% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
