About this 1.1ct natural heart diamond

This 1.1ct natural heart sits in the classic one-carat band, graded G 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 6565716630. Listed at 4 retailers as of October 31, 2026, with prices from $2,927 to $3,503, a $576 spread on the same certified stone. Blue Nile lists it at $3,503. 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.
