About this 0.5ct natural heart diamond

This 0.5ct natural heart sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2517135798. Listed at 19 retailers as of November 2, 2026, with prices from $652 to $1,429, a $777 spread on the same certified stone. MOH London lists it at $1,429. 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.
