About this 4.05ct lab-grown oval diamond

This 4.05ct 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 LG762545315 or 762545315. Listed at 16 retailers, with prices from $3,128 to $15,437 at Novita Diamonds, a $12,309 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.
