About this 4.25ct lab-grown oval diamond

This 4.25ct 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 LG754563799 or 754563799. Listed at 15 retailers, with prices from $3,567 to $21,500 at Brilliant Earth, a $17,933 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.
