About this 0.51ct natural marquise diamond

This 0.51ct natural marquise sits in the half to three-quarter carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6565139322. Listed at 7 retailers as of November 2, 2026, with prices from HK$4,784 to HK$8,107, a HK$3,323 spread on the same certified stone. Frank Darling lists it at HK$8,107. 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.
