About this 1.37ct lab-grown oval diamond

This 1.37ct lab-grown oval sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG683568558 or 683568558. Listed at 15 retailers, with prices from $235 to $1,940 at Rare Carat, a $1,705 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.
