About this 0.54ct natural marquise diamond

This 0.54ct natural marquise sits in the half to three-quarter carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6551646852. Listed at 2 retailers as of November 4, 2026, with prices from $765 to $929, a $164 spread on the same certified stone. 77 Diamonds lists it at $929. 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.
