About this 1.71ct lab-grown radiant diamond

This 1.71ct lab-grown radiant sits in the one-and-a-half to two carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG627457309 or 627457309. Listed at 16 retailers, with prices from $265 to $2,040 at Brilliant Earth, a $1,775 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.
