About this 1.5ct natural marquise diamond

This 1.5ct natural marquise sits in the one-and-a-half to two 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 2557054722. Listed at 13 retailers as of November 1, 2026, with prices from HK$66,464 to HK$92,835, a HK$26,371 spread on the same certified stone. Diamonds Direct lists it at HK$92,835. 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.
