Kabana 14k Gold Mother Of Pearl Gemstone Ring

Kabana 14k Yellow Gold Gemstone Inlay Ring. The stones were sold to me as MOP, Onyx,Amethyst, Topaz and Pink Sapphire I have not had them authenticated and they could be something else so I am listing as gemstones. However, Kabana always uses top of the line gemstones. The ring is well crafted as expected from Kabana. The ring measures approx 18mm north/south. Size 5.75 approx. Marked 14k KBN (Kabana). This is a vintage ring. The ring weighs approx. 9.2 grams May benefit from a polish.
