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 831668557. Listed at 13 retailers as of October 30, 2026, with prices from $565 to $2,292, a $1,727 spread on the same certified stone. NZ Jewellers lists it at $2,292. 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.
