About this 0.9ct natural asscher diamond

This 0.9ct natural asscher sits in the just-under-one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5166675339. Listed at 7 retailers as of November 1, 2026, with prices from £2,128 to £3,134, a £1,006 spread on the same certified stone. The Diamond Guys lists it at £3,134. 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.
