The birthstone for October is the opal . Opals symbolize hope, faithfulness, and confidence.
COLOR: Multicolor, generally white with colorful flecks, known as play-of-color. The base color can range widely in color as well. Warm colors are rarer and more valuable than cool colors.
DURABILITY: Fair to poor toughness. Opals, because they have no regular crystaline structure and frequently contain a high percentage of water, should be treated with care.
CARE: Treat gently. Wipe opals with a soft cloth. Bring to Kay Jewelers to have the stone cleaned and checked professionally. Never use ultrasonic or steam cleaners.
