About this 1.51ct lab-grown cushion diamond

This 1.51ct 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 LG757522512 or 757522512. Listed at 6 retailers as of November 2, 2026, with prices from $582 to $1,550, a $968 spread on the same certified stone. MOH London lists it at $1,550. 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.
