This 5.15ct lab-grown oval sits in the over five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG607398766 or 607398766. Listed at 26 retailers as of October 29, 2026, with prices from £5,085 to £19,318, a £14,233 spread on the same certified stone. Taylor and Hart lists it at £19,318. 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.
