About this 3.76ct lab-grown cushion diamond

This 3.76ct lab-grown cushion sits in the three to five carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG600378481 or 600378481. Listed at 10 retailers as of October 25, 2026, with prices from £404 to £1,881, a £1,477 spread on the same certified stone. Brilliant Earth lists it at £1,881. 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.
