About this 1.7ct natural radiant diamond

This 1.7ct natural radiant sits in the one-and-a-half to two carat band, graded D colour (colourless) and I1 clarity (included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1528956397. Listed at 10 retailers as of October 30, 2026, with prices from $6,809 to $15,335, a $8,526 spread on the same certified stone. NZ Jewellers lists it at $15,335. 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.
