About this 0.75ct natural heart diamond

This 0.75ct natural heart sits in the just-under-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 1537743388. Listed at 4 retailers as of November 6, 2026, with prices from $1,119 to $2,089, a $970 spread on the same certified stone. GemTrove lists it at $2,089. 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.
