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 LG780656564 or 780656564. Listed at 24 retailers as of October 29, 2026, with prices from $813 to $7,062, a $6,249 spread on the same certified stone. Brilliant Earth lists it at $7,062. 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.
