About this 1.2ct natural asscher diamond

This 1.2ct natural asscher sits in the classic one-carat band, graded I 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 1508002418. Listed at 8 retailers as of November 4, 2026, with prices from $3,249 to $4,873, a $1,624 spread on the same certified stone. Washington Diamond lists it at $4,873. 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.
