About this 1.17ct natural heart diamond

This 1.17ct natural heart sits in the classic one-carat band, graded J 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 6551034953. Listed at 5 retailers as of October 31, 2026, with prices from $1,999 to $2,409, a $410 spread on the same certified stone. Blue Nile lists it at $2,409. 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.
