About this 1.51ct natural oval diamond

This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 553255370. Listed at 15 retailers as of November 5, 2026, with prices from $11,030 to $21,346, a $10,316 spread on the same certified stone. NZ Jewellers lists it at $21,346. 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.
