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 I1 clarity (included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7451897330. Listed at 10 retailers as of October 30, 2026, with prices from £4,667 to £9,784, a £5,118 spread on the same certified stone. NZ Jewellers lists it at £9,784. 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.
