This 1.51ct lab-grown cushion sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG668407413 or 668407413. Listed at 12 retailers as of November 1, 2026, with prices from $504 to $2,390, a $1,886 spread on the same certified stone. Do Amore Diamonds lists it at $2,390. 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.
