About this 1.23ct natural oval diamond

This 1.23ct natural oval sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2487659567. Listed at 5 retailers as of November 5, 2026, with prices from $4,244 to $6,819, a $2,575 spread on the same certified stone. 77 Diamonds lists it at $6,819. 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.
