This 1.71ct 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 1498741957. Listed at 3 retailers as of November 2, 2026, with a relatively tight 13% spread, which is unusual at this carat range and suggests competitive pricing across the listings.
