About this 0.64ct natural heart diamond
This 0.64ct natural heart sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2536877635. Listed at 4 retailers as of October 31, 2026, with prices from $417 to $547, a $130 spread on the same certified stone. Blue Nile lists it at $547. 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.
