About this 3.06ct lab-grown cushion diamond

This 3.06ct lab-grown cushion sits in the three to five carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG729555715 or 729555715. Listed at 15 retailers as of October 31, 2026, with prices from £1,087 to £3,883, a £2,796 spread on the same certified stone. Taylor and Hart lists it at £3,883. 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.
