About this 3.55ct lab-grown oval diamond

This 3.55ct 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 LG634444003 or 634444003. Listed at 8 retailers, with prices from $4,289 to $18,474 at Mervis Diamond Importers, a $14,185 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.
