About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6561587509. Listed at 13 retailers as of November 4, 2026, with prices from HK$60,583 to HK$108,595, a HK$48,012 spread on the same certified stone. With Clarity lists it at HK$108,595. 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.
