Nola Collection Pearls Malachite & Amethyst. The NOLA collection is inspired by the glamour and decadence of New Orleans, Mardi Gras and the life of a courtesan. We have used rare precious and semiprecious stones to create a regal collection that gives homage to the rich, culturally diverse Crescent City (New Orleans). The lines, form and overall design exude glamour. Live the decadence of a Parisian courtesan through this regal collection. Pearls are said to have lunar elements which is believed to help balance the emotions and bring inner wisdom.
