About this 1.51ct natural oval diamond

This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 794652789. Listed at 18 retailers as of October 30, 2026, with prices from $5,559 to $12,752, a $7,193 spread on the same certified stone. NZ Jewellers lists it at $12,752. 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.
