About this 0.9ct natural radiant diamond

This 0.9ct natural radiant sits in the just-under-one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6421749494. Listed at 13 retailers as of October 28, 2026, with prices from $3,081 to $6,784, a $3,704 spread on the same certified stone. NZ Jewellers lists it at $6,784. 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.
