About this 0.55ct natural heart diamond

This 0.55ct natural heart sits in the half to three-quarter carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6542499728. Listed at 2 retailers as of November 6, 2026, with prices from $520 to $643, a $122 spread on the same certified stone. 77 Diamonds lists it at $643. 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.
