About this 3.64ct lab-grown heart diamond

This 3.64ct lab-grown heart sits in the three to five carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG821656619 or 821656619. Listed at 7 retailers as of October 31, 2026, with prices from $3,316 to $10,491, a $7,175 spread on the same certified stone. With Clarity lists it at $10,491. 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.
