About this 3.06ct lab-grown heart diamond

This 3.06ct 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 LG619433990 or 619433990. Listed at 19 retailers as of October 30, 2026, with prices from $1,220 to $10,840, a $9,620 spread on the same certified stone. Do Amore Diamonds lists it at $10,840. 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.
