About this 1.65ct lab-grown cushion diamond

This 1.65ct lab-grown cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG530226714 or 530226714. Listed at 7 retailers as of November 1, 2026, with prices from €495 to €1,321, a €826 spread on the same certified stone. MOH London lists it at €1,321. 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.
