About this 1.21ct natural oval diamond

This 1.21ct natural oval sits in the classic one-carat band, graded I 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 7511961673. Listed at 17 retailers as of November 4, 2026, with a 108% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
