About this 3.5ct lab-grown oval diamond

This 3.5ct 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 LG754595256 or 754595256. Listed at 23 retailers, with prices from $2,045 to $14,060 at Brilliant Earth, a $12,015 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.
