San Diego's most innovative jewelery designer, Charles Koll, brings in a selection of vibrant stones to Charles Koll Jewelers. San Diegans can get a peek at some of the most unusual and vibrantly colored gemstones from all over the world during Charles Koll Jewelers' one-day-only showcase event at their location in Fashion Valley Mall (open to the public). The longtime San Diego jeweler is bringing in a selection of sapphires, rubies, tanzanite, tourmaline, and spinel for viewing. Guests can browse and enjoy the beauty of the stones, and even find out what colors work best for their complexion. A lapidary (stone cutting) artist from Hawaii will be in the store to answer questions about how pieces are made and stones are selected. Reservations are recommended; call 619.298.5655 to schedule.
