About this 0.7ct natural marquise diamond

This 0.7ct natural marquise sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1563602791. Listed at 10 retailers as of November 4, 2026, with prices from HK$6,121 to HK$10,988, a HK$4,867 spread on the same certified stone. Helzberg Diamonds lists it at HK$10,988. 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.
