This 1.65ct lab-grown cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG679510235 or 679510235. Listed at 11 retailers as of November 1, 2026, with prices from $350 to $1,579, a $1,229 spread on the same certified stone. Brilliance lists it at $1,579. 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.
