This 1.27ct lab-grown princess sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG841656178 or 841656178. Listed at 20 retailers as of October 30, 2026, with prices from £142 to £870, a £728 spread on the same certified stone. Reve Diamonds lists it at £870. 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.
