About this 1.3ct natural round diamond

This 1.3ct natural round sits in the one-and-a-quarter to one-and-a-half carat band, graded J colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by GIA 6421723137. Listed at 19 retailers as of October 30, 2026, with prices from $2,929 to $7,040, a $4,111 spread on the same certified stone. NZ Jewellers lists it at $7,040. 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.
