About this 3.91ct lab-grown oval diamond

This 3.91ct lab-grown oval sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG754595504 or 754595504. Listed at 24 retailers, with prices from $2,526 to $14,290 at Brilliant Earth, a $11,764 spread on the same certified stone. 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.
