About this 0.51ct natural asscher diamond

This 0.51ct natural asscher sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1285858814. Listed at 4 retailers as of November 4, 2026, with prices from £568 to £764, a £197 spread on the same certified stone. Wholesale Diamonds Direct lists it at £764. 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.
