About this 3.07ct lab-grown cushion diamond

This 3.07ct lab-grown cushion sits in the three to five carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG680505813 or 680505813. Listed at 2 retailers as of November 4, 2026, with prices from £1,261 to £2,820, a £1,559 spread on the same certified stone. Michael Trio lists it at £2,820. 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.
