About this 1.3ct natural round diamond

This 1.3ct natural round sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a top-tier cut grade and certified by GIA 3555632259. Listed at 10 retailers as of October 29, 2026, with a 90% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
