About this 8.35ct lab-grown cushion diamond

This 8.35ct lab-grown cushion sits in the over five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG578321254 or 578321254. Listed at 14 retailers as of October 31, 2026, with prices from $2,278 to $8,599, a $6,321 spread on the same certified stone. Brilliant Earth lists it at $8,599. 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.
