About this 1ct natural radiant diamond

This 1ct natural radiant sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2546076805. Listed at 15 retailers as of October 27, 2026, with prices from $3,701 to $8,401, a $4,699 spread on the same certified stone. NZ Jewellers lists it at $8,401. 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.
