This 1.72ct lab-grown princess sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG508131116 or 508131116. Listed at 15 retailers as of November 4, 2026, with prices from £310 to £1,407, a £1,098 spread on the same certified stone. MOH London lists it at £1,407. 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.
