This 1.56ct lab-grown heart sits in the one-and-a-half to two carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included) and certified by IGI LG786682109 or 786682109. Listed at 24 retailers as of October 27, 2026, with prices from $322 to $1,689, a $1,367 spread on the same certified stone. With Clarity lists it at $1,689. 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.
