About this 1.5ct natural marquise diamond

This 1.5ct natural marquise sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2557911893. Listed at 5 retailers as of November 6, 2026, with prices from HK$51,123 to HK$63,628, a HK$12,504 spread on the same certified stone. 77 Diamonds lists it at HK$63,628. 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.
