About this 0.77ct natural heart diamond

This 0.77ct natural heart sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included) and certified by GIA 1206874268. Listed at 2 retailers as of November 5, 2026, with a relatively tight 12% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
