About this 1.51ct natural asscher diamond

This 1.51ct natural asscher sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5151756021. Listed at 16 retailers as of November 4, 2026, with prices from £5,309 to £11,340, a £6,031 spread on the same certified stone. NZ Jewellers lists it at £11,340. 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.
