About this 17.51ct lab-grown cushion diamond

This 17.51ct 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 LG799670786 or 799670786. Listed at 6 retailers as of October 31, 2026, with prices from $5,940 to $33,107, a $27,167 spread on the same certified stone. Brilliant Earth lists it at $33,107. 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.
