About this 1.56ct lab-grown oval diamond

This 1.56ct lab-grown oval sits in the one-and-a-half to two carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840634396 or 840634396. Listed at 12 retailers as of October 28, 2026, with prices from £261 to £2,827, a £2,566 spread on the same certified stone. Rare Carat lists it at £2,827. 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.
