About this 1.73ct natural oval diamond

This 1.73ct natural oval sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1559520004. Listed at 19 retailers as of October 30, 2026, with prices from $11,925 to $21,492, a $9,567 spread on the same certified stone. NZ Jewellers lists it at $21,492. 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.
