About this 1.43ct natural round diamond

This 1.43ct natural round sits in the one-and-a-quarter to one-and-a-half carat band, graded L colour (faint-tinted) and SI2 clarity (slightly-included), with a top-tier cut grade and certified by GIA 7542471807. Listed at 12 retailers as of November 4, 2026, with a 188% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
