This 1.78ct lab-grown princess sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG499106634 or 499106634. Listed at 3 retailers as of October 29, 2026, with prices from £524 to £1,418, a £894 spread on the same certified stone. Brilliant Earth lists it at £1,418. 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.
