About this 1.5ct natural round diamond

This 1.5ct natural round sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by GIA 2566441515. Listed at 23 retailers as of October 30, 2026, with prices from $4,301 to $9,491, a $5,190 spread on the same certified stone. NZ Jewellers lists it at $9,491. 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.
