About this 0.51ct natural oval diamond

This 0.51ct natural oval sits in the half to three-quarter carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 687512850. Listed at 16 retailers as of October 30, 2026, with prices from $384 to $1,994, a $1,611 spread on the same certified stone. NZ Jewellers lists it at $1,994. 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.
