About this 1ct natural radiant diamond

This 1ct natural radiant sits in the classic one-carat band, graded I 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 6442748650. Listed at 16 retailers as of October 30, 2026, with prices from $2,324 to $6,158, a $3,833 spread on the same certified stone. NZ Jewellers lists it at $6,158. 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.
