About this 0.63ct natural heart diamond

This 0.63ct natural heart sits in the half to three-quarter carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2536234268. Listed at 4 retailers as of November 4, 2026, with prices from $543 to $692, a $149 spread on the same certified stone. 77 Diamonds lists it at $692. 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.
