About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7558189154. Listed at 10 retailers as of October 30, 2026, with prices from HK$77,829 to HK$105,702, a HK$27,872 spread on the same certified stone. Yorxs lists it at HK$105,702. 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.
