About this 1.65ct lab-grown radiant diamond

This 1.65ct lab-grown radiant sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG707550338 or 707550338. Listed at 26 retailers, with prices from $362 to $4,070 at Brilliant Earth, a $3,708 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.
