About this 3.65ct lab-grown cushion diamond

This 3.65ct lab-grown cushion sits in the three to five carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG784602931 or 784602931. Listed at 4 retailers as of October 31, 2026, with prices from £3,845 to £5,500, a £1,654 spread on the same certified stone. Zales lists it at £5,500. 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.
