Antique 14K White Gold Diamond and Onyx Ring

Offering an antique 14k white gold ring with four diamonds and thee onyx stones dyed in a rich green color. This ring weighs 3.33 grams and is a size 3-3/4. Ring is not marked but is tested true for 14K gold. The diamonds are an unusual cut 

I had the local jeweler/gemologist verify the dyed onyx and diamonds and gold content. I was told by the former owner it was from her family in Portugal from the early to mid 1800's
