This 1.51ct natural round sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by GIA 2231816580. Listed at 21 retailers as of October 30, 2026, with prices from $7,162 to $15,668, a $8,506 spread on the same certified stone. NZ Jewellers lists it at $15,668. 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.
