About this 0.99ct lab-grown cushion diamond

This 0.99ct lab-grown cushion sits in the just-under-one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG681521993 or 681521993. Listed at 16 retailers as of October 30, 2026, with prices from $196 to $1,117, a $921 spread on the same certified stone. Reve Diamonds lists it at $1,117. 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.
