About this 4.56ct lab-grown oval diamond

This 4.56ct 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 LG762544409 or 762544409. Listed at 14 retailers, with prices from $5,726 to $24,048 at Taylor and Hart, a $18,322 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.
