This 1.28ct lab-grown asscher sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG831690415 or 831690415. Listed at 11 retailers as of October 29, 2026, with prices from $209 to $1,190, a $981 spread on the same certified stone. Brilliant Earth lists it at $1,190. 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.
