About this 1.23ct natural heart diamond

This 1.23ct natural heart sits in the classic one-carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1429416868. Listed at 13 retailers as of November 2, 2026, with prices from $4,759 to $8,885, a $4,127 spread on the same certified stone. MOH London lists it at $8,885. 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.
