About this 1.02ct natural radiant diamond

This 1.02ct natural radiant sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5212114984. Listed at 4 retailers as of October 31, 2026, with prices from $4,605 to $6,938, a $2,333 spread on the same certified stone. 77 Diamonds lists it at $6,938. 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.
