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 LG579399383 or 579399383. Listed at 29 retailers as of October 30, 2026, with prices from $10,995 to $71,078, a $60,083 spread on the same certified stone. Do Amore Diamonds lists it at $71,078. 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.
