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 LG830620268 or 830620268. Listed at 15 retailers as of October 29, 2026, with prices from $265 to $1,694, a $1,429 spread on the same certified stone. Brilliant Earth lists it at $1,694. 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.
