This 1.21ct lab-grown asscher sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG687529289 or 687529289. Listed at 2 retailers as of October 30, 2026, with prices from $732 to $951, a $219 spread on the same certified stone. Diamond Quarter lists it at $951. 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.
