This 3.66ct lab-grown princess sits in the three to five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG476187188 or 476187188. Listed at 16 retailers as of November 1, 2026, with prices from £794 to £5,015, a £4,222 spread on the same certified stone. Do Amore Diamonds lists it at £5,015. 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.
