About this 1.53ct natural radiant diamond

This 1.53ct natural radiant sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1537566532. Listed at 7 retailers as of October 30, 2026, with prices from $4,241 to $7,845, a $3,604 spread on the same certified stone. NZ Jewellers lists it at $7,845. 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.
