This 1.6ct 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 LG551291037 or 551291037. Listed at 5 retailers as of October 29, 2026, with prices from $602 to $1,678, a $1,076 spread on the same certified stone. MOH London lists it at $1,678. 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.
