This 1.87ct 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 standard cut grade and certified by IGI LG436046697 or 436046697. Listed at 5 retailers as of November 1, 2026, with prices from $2,561 to $7,577, a $5,017 spread on the same certified stone. MOH London lists it at $7,577. 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.
