This 1.54ct 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 LG605341593 or 605341593. Listed at 10 retailers as of October 26, 2026, with prices from $234 to $1,146, a $912 spread on the same certified stone. MOH London lists it at $1,146. 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.
