This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 642440186. Listed at 3 retailers as of November 4, 2026, with prices from £8,709 to £12,495, a £3,787 spread on the same certified stone. MOH London lists it at £12,495. 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.
