About this 1ct natural asscher diamond

This 1ct natural asscher sits in the classic one-carat band, graded D 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 1435602864. Listed at 10 retailers as of November 1, 2026, with prices from £1,144 to £1,745, a £601 spread on the same certified stone. 77 Diamonds lists it at £1,745. 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.
