About this 1.51ct natural radiant diamond

This 1.51ct natural radiant sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6522876565. Listed at 5 retailers as of November 2, 2026, with prices from $5,888 to $10,890, a $5,002 spread on the same certified stone. NZ Jewellers lists it at $10,890. 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.
