About this 1.29ct natural heart diamond

This 1.29ct natural heart sits in the one-and-a-quarter to one-and-a-half 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 2235866359. Listed at 3 retailers as of November 4, 2026, with prices from $6,279 to $10,240, a $3,961 spread on the same certified stone. MOH London lists it at $10,240. 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.
