About this 2.15ct lab-grown cushion diamond

This 2.15ct lab-grown cushion sits in the two to three carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG436045078 or 436045078. Listed at 6 retailers as of October 29, 2026, with prices from $4,087 to $11,505, a $7,417 spread on the same certified stone. MOH London lists it at $11,505. 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.
