About this 1.25ct natural heart diamond

This 1.25ct natural heart sits in the one-and-a-quarter to one-and-a-half carat band, graded I 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 2151070667. Listed at 3 retailers as of November 4, 2026, with prices from $5,923 to $9,654, a $3,730 spread on the same certified stone. MOH London lists it at $9,654. 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.
