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 757502394. Listed at 14 retailers as of November 2, 2026, with prices from HK$3,193 to HK$24,869, a HK$21,676 spread on the same certified stone. Flawless Fine Jewelry lists it at HK$24,869. 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.
