About this 2.5ct natural heart diamond

This 2.5ct 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 6445191386. Listed at 12 retailers as of November 2, 2026, with prices from $20,233 to $33,326, a $13,093 spread on the same certified stone. MOH London lists it at $33,326. 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.
