About this 1.51ct natural radiant diamond

This 1.51ct natural radiant sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7436128858. Listed at 12 retailers as of October 27, 2026, with prices from $8,881 to $14,803, a $5,922 spread on the same certified stone. NZ Jewellers lists it at $14,803. 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.
