This 0.77ct lab-grown oval sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG778616845 or 778616845. Listed at 20 retailers as of October 29, 2026, with prices from £168 to £1,739, a £1,571 spread on the same certified stone. Do Amore Diamonds lists it at £1,739. 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.
