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 October 30, 2026, with prices from €612 to €1,979, a €1,367 spread on the same certified stone. NZ Jewellers lists it at €1,979. 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.
