About this 3ct natural heart diamond

This 3ct 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 5476882258. Listed at 21 retailers as of November 4, 2026, with prices from £18,590 to £31,900, a £13,310 spread on the same certified stone. MOH London lists it at £31,900. 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.
