About this 1.5ct natural round diamond

This 1.5ct 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 very-good cut grade and certified by GIA 5533137080. Listed at 12 retailers as of November 5, 2026, with prices from $3,200 to $7,575, a $4,375 spread on the same certified stone. NZ Jewellers lists it at $7,575. 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.
