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 SI1 clarity (slightly-included), with a very-good cut grade and certified by GIA 2537839680. Listed at 20 retailers as of October 30, 2026, with prices from $5,700 to $13,403, a $7,703 spread on the same certified stone. NZ Jewellers lists it at $13,403. 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.
