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 1198496545. Listed at 12 retailers as of November 1, 2026, with prices from $823 to $1,220, a $397 spread on the same certified stone. Yorxs lists it at $1,220. 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.
