This 1.51ct lab-grown cushion sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG575367259 or 575367259. Listed at 8 retailers as of November 1, 2026, with prices from $408 to $1,087, a $679 spread on the same certified stone. MOH London lists it at $1,087. 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.
