About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7556418276. Listed at 13 retailers as of November 1, 2026, with prices from HK$61,998 to HK$111,116, a HK$49,119 spread on the same certified stone. With Clarity lists it at HK$111,116. 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.
