About this 1.5ct lab-grown oval diamond

This 1.5ct lab-grown oval sits in the one-and-a-half to two carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG761553374 or 761553374. Listed at 27 retailers as of October 27, 2026, with prices from £355 to £2,643, a £2,288 spread on the same certified stone. Brilliant Earth lists it at £2,643. 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.
