About this 0.99ct lab-grown cushion diamond

This 0.99ct lab-grown cushion sits in the just-under-one-carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG816608204 or 816608204. Listed at 8 retailers as of October 31, 2026, with prices from $426 to $1,575, a $1,149 spread on the same certified stone. Taylor and Hart lists it at $1,575. 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.
