About this 1.2ct lab-grown princess diamond

This 1.2ct lab-grown princess sits in the classic one-carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG605341651 or 605341651. Listed at 8 retailers as of November 2, 2026, with prices from £266 to £784, a £518 spread on the same certified stone. MOH London lists it at £784. 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.
