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 I1 clarity (included), with a very-good cut grade and certified by GIA 6415661187. Listed at 12 retailers as of October 30, 2026, with prices from $5,009 to $11,355, a $6,346 spread on the same certified stone. NZ Jewellers lists it at $11,355. 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.
