About this 1.58ct natural round diamond

This 1.58ct 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 2221593697. Listed at 17 retailers as of November 4, 2026, with a 31% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
