About this 1.51ct natural oval diamond

This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded L colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6422519481. Listed at 12 retailers as of November 1, 2026, with prices from $2,922 to $5,450, a $2,528 spread on the same certified stone. Wholesale Diamonds Direct lists it at $5,450. 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.
