About this 1.51ct lab-grown oval diamond

This 1.51ct lab-grown oval sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG761553145 or 761553145. Listed at 28 retailers, with prices from $465 to $4,980 at Brilliant Earth, a $4,515 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.
