About this 0.31ct natural heart diamond

This 0.31ct natural heart sits in the sub-half-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by HRD 260000264672. Listed at 4 retailers as of October 29, 2026, with prices from $374 to $634, a $260 spread on the same certified stone. MOH London lists it at $634. 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.
