About this 3.56ct lab-grown heart diamond

This 3.56ct lab-grown heart sits in the three to five carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 3 retailers as of October 30, 2026, with prices from $1,649 to $4,116, a $2,467 spread on the same certified stone. Diamond Exchange Canada lists it at $4,116. 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.
