About this 3.03ct natural heart diamond

This 3.03ct natural heart sits in the three to five carat band, graded H 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 5483626789. Listed at 17 retailers as of November 4, 2026, with prices from £16,486 to £30,346, a £13,860 spread on the same certified stone. MOH London lists it at £30,346. 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.
