About this 1.51ct natural oval diamond

This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 851622831. Listed at 11 retailers as of October 31, 2026, with prices from $5,515 to $11,269, a $5,754 spread on the same certified stone. MOH London lists it at $11,269. 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.
