About this 1.7ct natural oval diamond

This 1.7ct natural oval sits in the one-and-a-half to two carat band, graded M colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1558810257. Listed at 13 retailers as of November 5, 2026, with prices from HK$12,540 to HK$35,206, a HK$22,666 spread on the same certified stone. NZ Jewellers lists it at HK$35,206. 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.
