About this 1.6ct natural round diamond

This 1.6ct 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 2241024031. Listed at 11 retailers as of November 5, 2026, with a 28% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
