About this 0.45ct natural heart diamond

This 0.45ct natural heart sits in the sub-half-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6562289542. Listed at 3 retailers as of October 29, 2026, with prices from $616 to $771, a $155 spread on the same certified stone. 77 Diamonds lists it at $771. 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.
