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 2205875603. Listed at 19 retailers as of November 4, 2026, with prices from $15,171 to $28,496, a $13,325 spread on the same certified stone. NZ Jewellers lists it at $28,496. 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.
