About this 1.54ct natural radiant diamond

This 1.54ct natural radiant sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5166008528. Listed at 21 retailers as of October 30, 2026, with prices from $10,154 to $18,252, a $8,098 spread on the same certified stone. NZ Jewellers lists it at $18,252. 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.
