About this 1.09ct lab-grown asscher diamond

This 1.09ct lab-grown asscher sits in the classic one-carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG831679805 or 831679805. Listed at 18 retailers as of November 1, 2026, with prices from $184 to $990, a $806 spread on the same certified stone. Brilliant Earth lists it at $990. 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.
