About this 1.61ct lab-grown cushion diamond

This 1.61ct lab-grown cushion sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG551210694 or 551210694. Listed at 5 retailers as of October 31, 2026, with prices from £207 to £1,936, a £1,728 spread on the same certified stone. Michael Trio lists it at £1,936. 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.
