About this 0.8ct natural marquise diamond

This 0.8ct natural marquise sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1568457570. Listed at 6 retailers as of October 31, 2026, with prices from HK$14,711 to HK$18,524, a HK$3,813 spread on the same certified stone. Blue Nile lists it at HK$18,524. 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.
