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 November 5, 2026, with prices from £637 to £1,300, a £663 spread on the same certified stone. Do Amore Diamonds lists it at £1,300. 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.
