About this 1.7ct lab-grown heart diamond

This 1.7ct lab-grown heart sits in the one-and-a-half to two carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG818674172 or 818674172. Listed at 16 retailers as of October 27, 2026, with prices from $343 to $1,731, a $1,388 spread on the same certified stone. Brilliance lists it at $1,731. 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.
