This 1.51ct lab-grown princess sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG442069571 or 442069571. Listed at 10 retailers as of October 29, 2026, with prices from £1,082 to £3,605, a £2,522 spread on the same certified stone. MOH London lists it at £3,605. 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.
