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 standard cut grade stated by the retailer rather than the lab and certified by GIA 1548251981. Listed at 16 retailers as of November 2, 2026. 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.
