About this 2.51ct natural heart diamond

This 2.51ct natural heart sits in the two to three carat band, graded F colour (colourless) and SI2 clarity (slightly-included) and certified by GIA 6565780438. Listed at 3 retailers as of November 2, 2026, with a relatively tight 11% 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.
