About this 1.51ct natural oval diamond

This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded M 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 7558341333. Listed at 10 retailers as of November 4, 2026, with prices from HK$15,988 to HK$40,856, a HK$24,868 spread on the same certified stone. NZ Jewellers lists it at HK$40,856. 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.
