About this 0.55ct natural marquise diamond

This 0.55ct natural marquise sits in the half to three-quarter carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6552378263. Listed at 8 retailers as of November 6, 2026, with prices from $873 to $2,416, a $1,543 spread on the same certified stone. Do Amore Diamonds lists it at $2,416. 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.
