About this 0.73ct lab-grown heart diamond

This 0.73ct lab-grown heart sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG756513799 or 756513799. Listed at 13 retailers as of November 3, 2026, with prices from $754 to $4,553, a $3,799 spread on the same certified stone. MOH London lists it at $4,553. 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.
