This 1.55ct lab-grown heart sits in the one-and-a-half to two carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG831688164 or 831688164. Listed at 15 retailers as of October 28, 2026, with prices from $465 to $2,104, a $1,640 spread on the same certified stone. Reve Diamonds lists it at $2,104. 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.
