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 standard cut grade stated by the retailer rather than the lab and certified by GIA 2356661457. Listed at 10 retailers as of November 5, 2026, with prices from HK$30,848 to HK$67,731, a HK$36,883 spread on the same certified stone. NZ Jewellers lists it at HK$67,731. 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.
