This 1.53ct lab-grown radiant sits in the one-and-a-half to two carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG605396533 or 605396533. Listed at 3 retailers as of October 30, 2026, with prices from £1,045 to £2,426, a £1,381 spread on the same certified stone. Kay Jewelers lists it at £2,426. 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.
