About this 0.63ct natural heart diamond

This 0.63ct natural heart sits in the half to three-quarter carat band, graded G 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 1523752792. Listed at 5 retailers as of October 29, 2026, with prices from $466 to $613, a $147 spread on the same certified stone. Blue Nile lists it at $613. 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.
