About this 0.7ct natural marquise diamond

This 0.7ct natural marquise sits in the half to three-quarter carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2566609528. Listed at 10 retailers as of October 31, 2026, with prices from HK$8,143 to HK$14,594, a HK$6,451 spread on the same certified stone. Helzberg Diamonds lists it at HK$14,594. 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.
