About this 1.05ct natural heart diamond

This 1.05ct natural heart sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1563575344. Listed at 4 retailers as of November 5, 2026, with prices from $2,874 to $3,439, a $565 spread on the same certified stone. Blue Nile lists it at $3,439. 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.
