About this 0.53ct natural heart diamond

This 0.53ct natural heart sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5526766655. Listed at 3 retailers as of November 5, 2026, with prices from $506 to $681, a $174 spread on the same certified stone. 77 Diamonds lists it at $681. 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.
