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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 6482154364. Listed at 2 retailers as of October 28, 2026, with prices from $618 to $1,139, a $521 spread on the same certified stone. Diamond Quarter lists it at $1,139. 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.
