This 1.67ct lab-grown oval sits in the one-and-a-half to two carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG732554946 or 732554946. Listed at 7 retailers as of October 28, 2026, with prices from £364 to £1,933, a £1,569 spread on the same certified stone. Rare Carat lists it at £1,933. 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.
