This 1.89ct lab-grown oval sits in the one-and-a-half to two carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG818658544 or 818658544. Listed at 21 retailers as of October 28, 2026, with prices from £340 to £3,277, a £2,937 spread on the same certified stone. Rare Carat lists it at £3,277. 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.
