About this 0.37ct natural heart diamond

This 0.37ct natural heart sits in the sub-half-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 6561245328. Listed at 2 retailers as of November 2, 2026, with prices from $423 to $547, a $123 spread on the same certified stone. 77 Diamonds 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.
