About this 1.7ct natural asscher diamond

This 1.7ct natural asscher sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2398598311. Listed at 11 retailers as of October 31, 2026, with prices from £4,691 to £6,519, a £1,827 spread on the same certified stone. 77 Diamonds lists it at £6,519. 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.
