About this 1.3ct natural radiant diamond

This 1.3ct natural radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6551780264. Listed at 19 retailers as of November 5, 2026, with prices from $3,744 to $8,751, a $5,007 spread on the same certified stone. NZ Jewellers lists it at $8,751. 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.
