About this 0.3ct natural heart diamond

This 0.3ct natural heart sits in the sub-half-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6247070638. Listed at 15 retailers as of November 1, 2026, with prices from €265 to €610, a €346 spread on the same certified stone. MOH London lists it at €610. 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.
