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 IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 841646172. Listed at 16 retailers as of November 1, 2026, with prices from HK$52,004 to HK$99,740, a HK$47,736 spread on the same certified stone. NZ Jewellers lists it at HK$99,740. 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.
