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 £160 to £522, a £363 spread on the same certified stone. MOH London lists it at £522. 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.
