About this 0.4ct natural heart diamond

This 0.4ct 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 1236370456. Listed at 5 retailers as of October 26, 2026, with prices from $842 to $1,510, a $668 spread on the same certified stone. MOH London lists it at $1,510. 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.
