About this 3ct natural marquise diamond

This 3ct natural marquise sits in the three to five carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1565578534. Listed at 14 retailers as of November 5, 2026, with prices from HK$314,115 to HK$506,202, a HK$192,087 spread on the same certified stone. Helzberg Diamonds lists it at HK$506,202. 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.
