About this 0.45ct natural heart diamond

This 0.45ct 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 1565287591. Listed at 2 retailers as of November 5, 2026, with prices from $575 to $726, a $151 spread on the same certified stone. 77 Diamonds lists it at $726. 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.
