About this 1.59ct lab-grown radiant diamond

This 1.59ct lab-grown radiant sits in the one-and-a-half to two carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG677576304 or 677576304. Listed at 6 retailers, with prices from $544 to $4,320 at Do Amore Diamonds, a $3,776 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.
