About this 3.05ct natural heart diamond

This 3.05ct natural heart sits in the three to five 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 2517150984. Listed at 13 retailers as of November 4, 2026, with prices from £27,057 to £42,494, a £15,438 spread on the same certified stone. MOH London lists it at £42,494. 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.
