About this 1.62ct natural round diamond

This 1.62ct natural round sits in the one-and-a-half to two carat band, graded L colour (faint-tinted) and SI2 clarity (slightly-included), with a top-tier cut grade and certified by GIA 6405197041. Listed at 10 retailers as of November 4, 2026, with a relatively tight 24% spread, which is unusual at this carat range and suggests competitive pricing across the listings.
