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 5523878952. Listed at 16 retailers as of November 4, 2026, with prices from $4,417 to $9,882, a $5,465 spread on the same certified stone. MOH London lists it at $9,882. 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.
