About this 0.65ct natural heart diamond

This 0.65ct natural heart sits in the half to three-quarter carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5543447530. Listed at 7 retailers as of October 31, 2026, with prices from $876 to $1,543, a $668 spread on the same certified stone. GemTrove lists it at $1,543. 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.
