This 0.86ct 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 LG836610940 or 836610940. Listed at 19 retailers as of October 30, 2026, with prices from $363 to $1,759, a $1,396 spread on the same certified stone. MOH London lists it at $1,759. 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.
