About this 1.21ct natural heart diamond

This 1.21ct natural heart sits in the classic one-carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5486380052. Listed at 5 retailers as of November 4, 2026, with prices from $5,209 to $8,542, a $3,333 spread on the same certified stone. MOH London lists it at $8,542. 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.
