About this 1.05ct lab-grown heart diamond

This 1.05ct lab-grown heart sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6491049517. Listed at 2 retailers as of October 30, 2026, with prices from €763 to €1,557, a €794 spread on the same certified stone. Do Amore Diamonds lists it at €1,557. 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.
