About this 1.53ct natural radiant diamond

This 1.53ct natural radiant sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5232726560. Listed at 6 retailers as of November 3, 2026, with prices from $3,835 to $8,329, a $4,494 spread on the same certified stone. NZ Jewellers lists it at $8,329. 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.
