This 4.09ct lab-grown princess sits in the three to five carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG677563981 or 677563981. Listed at 18 retailers as of October 29, 2026, with prices from £738 to £3,321, a £2,583 spread on the same certified stone. Brilliant Earth lists it at £3,321. 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.
