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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 3535976437. Listed at 20 retailers as of November 1, 2026, with prices from HK$79,355 to HK$142,658, a HK$63,302 spread on the same certified stone. NZ Jewellers lists it at HK$142,658. 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.
