This 0.87ct lab-grown heart sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840619790 or 840619790. Listed at 4 retailers as of November 4, 2026, with prices from $584 to $2,141, a $1,557 spread on the same certified stone. Taylor and Hart lists it at $2,141. 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.
