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 SI2 clarity (slightly-included), with a very-good cut grade and certified by GIA 6565376363. Listed at 18 retailers as of October 30, 2026, with prices from $5,882 to $13,304, a $7,422 spread on the same certified stone. NZ Jewellers lists it at $13,304. 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.
