About this 0.64ct natural heart diamond

This 0.64ct 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 6502623436. Listed at 2 retailers as of October 29, 2026, with prices from $939 to $1,897, a $958 spread on the same certified stone. Fonder Diamond lists it at $1,897. 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.
