About this 0.73ct natural oval diamond

This 0.73ct natural oval sits in the half to three-quarter carat band, graded D colour (colourless) and I1 clarity (included) and certified by GIA 2557093555. Listed at 6 retailers as of October 29, 2026, with a 41% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
