About this 0.31ct natural heart diamond

This 0.31ct natural heart sits in the sub-half-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1193498639. Listed at 9 retailers as of October 29, 2026, with prices from $658 to $1,527, a $869 spread on the same certified stone. MOH London lists it at $1,527. 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.
