About this 4.01ct lab-grown oval diamond

This 4.01ct lab-grown oval sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG737589792 or 737589792. Listed at 8 retailers as of October 29, 2026, with prices from $4,889 to $15,679, a $10,789 spread on the same certified stone. Taylor and Hart lists it at $15,679. 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.
