About this 1.7ct natural asscher diamond

This 1.7ct natural asscher sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2245091342. Listed at 6 retailers as of October 30, 2026, with prices from £6,334 to £12,175, a £5,841 spread on the same certified stone. With Clarity lists it at £12,175. 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.
