About this 0.7ct natural heart diamond

This 0.7ct natural heart sits in the half to three-quarter carat band, graded J 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 2507146231. Listed at 8 retailers as of November 4, 2026, with prices from $1,173 to $2,960, a $1,787 spread on the same certified stone. MOH London lists it at $2,960. 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.
