This 3.06ct lab-grown cushion sits in the three to five carat band, graded D colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG818659078 or 818659078. Listed at 16 retailers as of October 29, 2026, with prices from £465 to £5,895, a £5,430 spread on the same certified stone. Brilliant Earth lists it at £5,895. 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.
