About this 1.57ct natural radiant diamond

This 1.57ct natural radiant sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5563167964. Listed at 8 retailers as of November 3, 2026, with prices from $12,759 to $20,549, a $7,789 spread on the same certified stone. NZ Jewellers lists it at $20,549. 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.
