About this 10.57ct lab-grown cushion diamond

This 10.57ct lab-grown cushion sits in the over five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG662491132 or 662491132. Listed at 15 retailers as of October 29, 2026, with prices from $1,925 to $9,170, a $7,245 spread on the same certified stone. Brilliant Earth lists it at $9,170. 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.
