About this 3.08ct lab-grown heart diamond

This 3.08ct lab-grown heart sits in the three to five carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7451595578. Listed at 21 retailers as of November 6, 2026, with prices from £647 to £5,080, a £4,433 spread on the same certified stone. Do Amore Diamonds lists it at £5,080. 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.
