About this 4ct lab-grown heart diamond

This 4ct 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 LG851660445 or 851660445. Listed at 11 retailers as of October 30, 2026, with prices from $913 to $3,771, a $2,858 spread on the same certified stone. Taylor and Hart lists it at $3,771. 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.
