This 6.5ct lab-grown oval sits in the over five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG818640334 or 818640334. Listed at 19 retailers as of October 28, 2026, with prices from $26,929 to $78,608, a $51,678 spread on the same certified stone. Taylor and Hart lists it at $78,608. 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.
