About this 2.3ct natural heart diamond

This 2.3ct natural heart sits in the two to three carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3555913733. Listed at 3 retailers as of November 5, 2026, with prices from $15,100 to $17,855, a $2,755 spread on the same certified stone. Blue Nile lists it at $17,855. 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.
