About this 3.03ct lab-grown heart diamond

This 3.03ct lab-grown heart sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG842612712 or 842612712. Listed at 21 retailers as of October 31, 2026, with prices from $2,338 to $9,521, a $7,184 spread on the same certified stone. Taylor and Hart lists it at $9,521. 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.
