This 0.78ct lab-grown oval sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG845672425 or 845672425. Listed at 16 retailers as of October 31, 2026, with prices from $532 to $2,236, a $1,704 spread on the same certified stone. Riddles Jewelry lists it at $2,236. 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.
