About this 0.7ct natural marquise diamond

This 0.7ct natural marquise sits in the half to three-quarter 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 6561551146. Listed at 15 retailers as of October 31, 2026, with prices from HK$10,602 to HK$19,168, a HK$8,566 spread on the same certified stone. Helzberg Diamonds lists it at HK$19,168. 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.
