About this 1.51ct natural oval diamond

This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6375880480. Listed at 17 retailers as of November 5, 2026, with prices from HK$35,018 to HK$69,212, a HK$34,195 spread on the same certified stone. NZ Jewellers lists it at HK$69,212. 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.
