About this 3.01ct lab-grown cushion diamond

This 3.01ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG838614778 or 838614778. Listed at 18 retailers as of October 27, 2026, with prices from £378 to £1,801, a £1,423 spread on the same certified stone. With Clarity lists it at £1,801. 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.
