This 1.5ct 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 LG851611249 or 851611249. Listed at 2 retailers as of November 3, 2026, with prices from $643 to $1,216, a $573 spread on the same certified stone. Taylor and Hart lists it at $1,216. 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.
