About this 3.03ct natural heart diamond

This 3.03ct natural heart sits in the three to five carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by HRD 200000050147. Listed at 10 retailers as of October 29, 2026, with prices from £12,167 to £19,160, a £6,993 spread on the same certified stone. MOH London lists it at £19,160. 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.
