About this 2.51ct natural heart diamond

This 2.51ct natural heart sits in the two to three carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1565816484. Listed at 8 retailers as of November 5, 2026, with prices from $15,416 to $23,646, a $8,229 spread on the same certified stone. Aurelinne lists it at $23,646. 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.
