About this 1.21ct natural heart diamond

This 1.21ct natural heart sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included) and certified by GIA 2205868195. Listed at a single retailer as of November 5, 2026. If it later appears at another store, Carat Hunter will surface the price comparison automatically. 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.
