This 1.87ct 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 LG831693550 or 831693550. Listed at 13 retailers as of October 28, 2026, with prices from $842 to $8,724, a $7,882 spread on the same certified stone. Brilliant Earth lists it at $8,724. 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.
