About this 1.55ct lab-grown cushion diamond

This 1.55ct lab-grown cushion sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG816607561 or 816607561. Listed at 10 retailers as of November 3, 2026, with prices from $701 to $2,201, a $1,500 spread on the same certified stone. MOH London lists it at $2,201. 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.
