About this 1.5ct natural radiant diamond

This 1.5ct natural radiant sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6532556600. Listed at 13 retailers as of November 6, 2026, with prices from $9,047 to $13,435, a $4,388 spread on the same certified stone. Riddles Jewelry lists it at $13,435. 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.
