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 LG768632254 or 768632254. Listed at 20 retailers, with prices from $1,754 to $14,040 at Brilliant Earth, a $12,286 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.
