About this 0.52ct natural heart diamond

This 0.52ct natural heart sits in the half to three-quarter 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 1558442811. Listed at 4 retailers as of November 5, 2026, with prices from $877 to $1,153, a $276 spread on the same certified stone. Blue Nile lists it at $1,153. 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.
