About this 1.07ct natural round diamond

This 1.07ct natural round sits in the classic one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by GIA 6157957391. Listed at 25 retailers as of October 31, 2026, with prices from $4,828 to $10,955, a $6,127 spread on the same certified stone. NZ Jewellers lists it at $10,955. 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.
