About this 0.51ct natural marquise diamond

This 0.51ct natural marquise sits in the half to three-quarter carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7448035214. Listed at 19 retailers as of November 5, 2026, with prices from HK$3,797 to HK$16,192, a HK$12,395 spread on the same certified stone. NZ Jewellers lists it at HK$16,192. 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.
