About this 1.51ct natural asscher diamond

This 1.51ct natural asscher sits in the one-and-a-half to two carat band, graded J 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 7541257855. Listed at 7 retailers as of November 1, 2026, with prices from $4,391 to $6,830, a $2,439 spread on the same certified stone. 77 Diamonds lists it at $6,830. 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.
