About this 1.25ct natural oval diamond

This 1.25ct natural oval sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6551482959. Listed at 13 retailers as of November 5, 2026, with prices from $3,994 to $8,255, a $4,261 spread on the same certified stone. NZ Jewellers lists it at $8,255. 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.
