About this 1.51ct lab-grown cushion diamond

This 1.51ct lab-grown cushion sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG487108020 or 487108020. Listed at 11 retailers as of November 4, 2026, with prices from $749 to $2,451, a $1,703 spread on the same certified stone. MOH London lists it at $2,451. 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.
