About this 0.51ct natural oval diamond

This 0.51ct natural oval sits in the half to three-quarter carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 810635121. Listed at 13 retailers as of November 1, 2026, with prices from HK$5,099 to HK$17,307, a HK$12,207 spread on the same certified stone. NZ Jewellers lists it at HK$17,307. 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.
