About this 0.3ct natural heart diamond

This 0.3ct natural heart sits in the sub-half-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 7553708742. Listed at 14 retailers as of November 1, 2026, with prices from €191 to €625, a €434 spread on the same certified stone. MOH London lists it at €625. 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.
