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 stated by the retailer rather than the lab and certified by GIA 1513580812. Listed at 10 retailers as of November 2, 2026, with prices from £2,235 to £12,719, a £10,484 spread on the same certified stone. Blue Nile lists it at £12,719. 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.
