This 1.81ct lab-grown heart sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG845656808 or 845656808. Listed at 16 retailers as of October 31, 2026, with prices from $468 to $5,000, a $4,532 spread on the same certified stone. Brilliant Earth lists it at $5,000. 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.
