About this 1.5ct lab-grown cushion diamond

This 1.5ct lab-grown cushion sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG619445817 or 619445817. Listed at 6 retailers as of November 1, 2026, with prices from $377 to $1,096, a $719 spread on the same certified stone. MOH London lists it at $1,096. 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.
