About this 0.3ct natural heart diamond

This 0.3ct 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 2586957. Listed at 3 retailers as of October 30, 2026, with prices from $594 to $864, a $270 spread on the same certified stone. Diamond Quarter lists it at $864. 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.
