This 1ct lab-grown heart sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG844678039 or 844678039. Listed at 16 retailers as of October 25, 2026, with prices from $355 to $1,772, a $1,417 spread on the same certified stone. MOH London lists it at $1,772. 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.
