About this 4.28ct lab-grown heart diamond

This 4.28ct lab-grown heart sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7531545665. Listed at 17 retailers as of November 2, 2026, with prices from €7,344 to €37,384, a €30,040 spread on the same certified stone. Kay Jewelers lists it at €37,384. 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.
