This 1.7ct lab-grown cushion sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG478103526 or 478103526. Listed at 12 retailers as of October 30, 2026, with prices from $546 to $2,365, a $1,819 spread on the same certified stone. MOH London lists it at $2,365. 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.
