About this 3.69ct lab-grown round diamond

This 3.69ct lab-grown round sits in the three to five carat band, graded I colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG605341378 or 605341378. Listed at 12 retailers as of October 28, 2026, with prices from £395 to £2,022, a £1,627 spread on the same certified stone. Adiamor lists it at £2,022. 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.
