About this 0.78ct lab-grown oval diamond

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 November 1, 2026, with prices from £279 to £1,171, a £892 spread on the same certified stone. Riddles Jewelry lists it at £1,171. 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.
