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 very-good cut grade and certified by IGI LG594312986 or 594312986. Listed at 7 retailers as of November 3, 2026, with prices from $537 to $1,559, a $1,021 spread on the same certified stone. MOH London lists it at $1,559. 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.
