About this 0.3ct natural heart diamond

This 0.3ct natural heart sits in the sub-half-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1559708539. Listed at 12 retailers as of October 31, 2026, with prices from £205 to £660, a £455 spread on the same certified stone. MOH London lists it at £660. 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.
