About this 1.38ct lab-grown oval diamond

This 1.38ct lab-grown oval sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG831684408 or 831684408. Listed at 3 retailers as of October 29, 2026, with prices from £328 to £822, a £493 spread on the same certified stone. Taylor and Hart lists it at £822. 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.
