About this 0.59ct natural marquise diamond

This 0.59ct natural marquise sits in the half to three-quarter carat band, graded I 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 1226139953. Listed at 3 retailers as of November 5, 2026, with prices from $844 to $1,330, a $486 spread on the same certified stone. 77 Diamonds lists it at $1,330. 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.
