About this 1.54ct natural radiant diamond

This 1.54ct natural radiant sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6521237639. Listed at 23 retailers as of November 5, 2026, with prices from $7,074 to $15,147, a $8,073 spread on the same certified stone. NZ Jewellers lists it at $15,147. 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.
