About this 1.5ct natural round diamond

This 1.5ct natural round sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by GIA 6495149114. Listed at 18 retailers as of November 5, 2026, with prices from $3,939 to $10,166, a $6,227 spread on the same certified stone. Adiamor lists it at $10,166. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
