This 1.7ct lab-grown cushion sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG436045072 or 436045072. Listed at 5 retailers as of October 29, 2026, with prices from $1,970 to $6,592, a $4,623 spread on the same certified stone. MOH London lists it at $6,592. 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.
