This 3.51ct lab-grown heart sits in the three to five carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG797650364 or 797650364. Listed at 11 retailers as of October 30, 2026, with prices from $1,742 to $7,878, a $6,136 spread on the same certified stone. Brilliant Earth lists it at $7,878. 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.
