About this 0.61ct natural heart diamond

This 0.61ct 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 1555278840. Listed at 4 retailers as of November 2, 2026, with prices from $807 to $1,035, a $227 spread on the same certified stone. 77 Diamonds lists it at $1,035. 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.
