About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded I 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 2554673570. Listed at 15 retailers as of November 1, 2026, with prices from HK$49,093 to HK$95,966, a HK$46,873 spread on the same certified stone. NZ Jewellers lists it at HK$95,966. 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.
