About this 2.05ct lab-grown cushion diamond

This 2.05ct lab-grown cushion sits in the two to three carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG436046502 or 436046502. Listed at 6 retailers as of October 29, 2026, with prices from £836 to £5,181, a £4,345 spread on the same certified stone. MOH London lists it at £5,181. 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.
