This 1.68ct 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 very-good cut grade and certified by IGI LG696545530 or 696545530. Listed at 24 retailers as of October 29, 2026, with prices from £318 to £2,978, a £2,660 spread on the same certified stone. Brilliant Earth lists it at £2,978. 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.
