About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3545622871. Listed at 14 retailers as of October 29, 2026, with prices from HK$50,764 to HK$91,704, a HK$40,939 spread on the same certified stone. MOH London lists it at HK$91,704. 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.
