About this 1.55ct natural round diamond

This 1.55ct natural round sits in the one-and-a-half to two carat band, graded L colour (faint-tinted) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by GIA 1558526536. Listed at 13 retailers as of November 5, 2026, with a 86% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
