0.52ct G SI2 Marquise Natural Diamond

About this 0.52ct natural marquise diamond

This 0.52ct natural marquise sits in the half to three-quarter carat band, graded G 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 1569139405. Listed at 5 retailers as of November 1, 2026, with prices from $583 to $1,008, a $425 spread on the same certified stone. Frank Darling lists it at $1,008. 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.
