About this 1.29ct lab-grown asscher diamond

This 1.29ct lab-grown asscher sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG636400939 or 636400939. Listed at 2 retailers as of October 30, 2026, with prices from €581 to €1,271, a €690 spread on the same certified stone. Shane Co lists it at €1,271. 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.
