About this 3.12ct natural oval diamond

This 3.12ct natural oval sits in the three to five 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 6315977731. Listed at 2 retailers as of October 30, 2026, with prices from $18,609 to $24,003, a $5,394 spread on the same certified stone. 77 Diamonds lists it at $24,003. 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.
