About this 3.5ct lab-grown round diamond

This 3.5ct lab-grown round sits in the three to five carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG847642600 or 847642600. Listed at 11 retailers as of October 31, 2026, with prices from $498 to $2,338, a $1,840 spread on the same certified stone. Michael Trio lists it at $2,338. 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.
