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 782691810. Listed at 13 retailers as of November 2, 2026, with prices from $407 to $3,170, a $2,763 spread on the same certified stone. Flawless Fine Jewelry lists it at $3,170. 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.
