About this 1.5ct natural marquise diamond

This 1.5ct natural marquise sits in the one-and-a-half to two carat band, graded G 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 6552564290. Listed at 16 retailers as of October 30, 2026, with prices from HK$63,271 to HK$114,420, a HK$51,149 spread on the same certified stone. NZ Jewellers lists it at HK$114,420. 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.
