0.58ct H SI2 Marquise Natural Diamond

About this 0.58ct natural marquise diamond

This 0.58ct natural marquise sits in the half to three-quarter carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6562226327. Listed at 8 retailers as of November 5, 2026, with prices from $485 to $955, a $470 spread on the same certified stone. Frank Darling lists it at $955. 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.
