This 1.51ct lab-grown cushion sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG838616398 or 838616398. Listed at 15 retailers as of November 1, 2026, with prices from $584 to $1,956, a $1,372 spread on the same certified stone. MOH London lists it at $1,956. 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.
