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 standard cut grade and certified by IGI LG605341033 or 605341033. Listed at 10 retailers as of November 2, 2026, with prices from $335 to $1,640, a $1,305 spread on the same certified stone. MOH London lists it at $1,640. 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.
