About this 1ct natural oval diamond

This 1ct natural oval sits in the classic one-carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 828653699. Listed at 15 retailers as of October 30, 2026, with prices from $5,445 to $10,688, a $5,243 spread on the same certified stone. NZ Jewellers lists it at $10,688. 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.
