This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded L colour (faint-tinted) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 768686231. Listed at 13 retailers as of November 5, 2026, with prices from £1,275 to £3,510, a £2,235 spread on the same certified stone. NZ Jewellers lists it at £3,510. 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.
