About this 1.7ct natural oval diamond

This 1.7ct natural oval sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2245084060. Listed at 17 retailers as of October 29, 2026, with prices from HK$39,069 to HK$89,951, a HK$50,882 spread on the same certified stone. NZ Jewellers lists it at HK$89,951. 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.
