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 LG842609731 or 842609731. Listed at 18 retailers as of October 30, 2026, with prices from $1,020 to $9,546, a $8,526 spread on the same certified stone. Brilliant Earth lists it at $9,546. 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.
