About this 5.18ct lab-grown heart diamond

This 5.18ct lab-grown heart sits in the over five carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2223224536. Listed at 9 retailers as of October 29, 2026, with prices from €2,330 to €7,168, a €4,839 spread on the same certified stone. MOH London lists it at €7,168. 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.
