About this 0.46ct natural heart diamond

This 0.46ct natural heart sits in the sub-half-carat band, graded H 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 1563283300. Listed at 3 retailers as of November 2, 2026, with prices from $539 to $670, a $131 spread on the same certified stone. 77 Diamonds lists it at $670. 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.
