About this 1.51ct natural round diamond

This 1.51ct natural round sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by GIA 6137986396. Listed at 25 retailers as of October 30, 2026, with prices from $10,767 to $19,672, a $8,905 spread on the same certified stone. NZ Jewellers lists it at $19,672. 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.
