About this 3ct lab-grown heart diamond

This 3ct lab-grown heart sits in the three to five carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG844683503 or 844683503. Listed at 12 retailers as of October 29, 2026, with prices from $1,738 to $5,384, a $3,646 spread on the same certified stone. MOH London lists it at $5,384. 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.
