About this 0.83ct lab-grown heart diamond

This 0.83ct lab-grown heart sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG831689005 or 831689005. Listed at 6 retailers as of November 5, 2026, with prices from $503 to $2,010, a $1,507 spread on the same certified stone. MOH London lists it at $2,010. 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.
