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 very-good cut grade and certified by IGI 626408265. Listed at 13 retailers as of November 5, 2026, with prices from HK$12,289 to HK$33,536, a HK$21,247 spread on the same certified stone. NZ Jewellers lists it at HK$33,536. 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.
