About this 0.65ct natural heart diamond

This 0.65ct 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 2536242964. Listed at 5 retailers as of October 31, 2026, with prices from $455 to $600, a $145 spread on the same certified stone. Blue Nile lists it at $600. 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.
