About this 0.52ct natural heart diamond

This 0.52ct 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 2546121541. Listed at 3 retailers as of November 6, 2026, with prices from $555 to $708, a $153 spread on the same certified stone. 77 Diamonds lists it at $708. 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.
