About this 1.2ct natural asscher diamond

This 1.2ct natural asscher sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6521939170. Listed at 12 retailers as of November 1, 2026, with prices from £1,058 to £2,406, a £1,348 spread on the same certified stone. Do Amore Diamonds lists it at £2,406. 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.
