Quick Answer
What is October’s birthstone?
October’s birthstone is opal. Iridescent opal — October's birthstone — displays a play of color unlike any other gem, symbolizing hope, creativity, and possibility. Hand-set into pendants, earrings, and rings at our Snellville atelier.
About Opal — the October Birthstone
Opal is October’s traditional birthstone — and unlike every other gem on this list, opal is amorphous rather than crystalline. Its signature play-of-color comes from microscopic silica spheres diffracting light. Opal sits at 5.5–6.5 on the Mohs scale — softer than quartz and water-sensitive, requiring careful wear.
ATL Luxury Jewelers stocks opal across pendants, stud and drop earrings, and protected-setting rings set in 14K and 18K gold or platinum. Varieties include black opal (Lightning Ridge, Australia — dark body with flashing color, the most prized), white opal (Coober Pedy, Australia — light body with pastel flashes, more affordable), boulder opal (Queensland — opal veins in ironstone matrix), and fire opal (Mexico — translucent orange/red, transparent rather than flashy).
Opal pairs beautifully with yellow gold for vintage warmth or platinum for a modern sharp contrast. Tourmaline is October’s modern alternate birthstone, available in every color and harder than opal — we stock both.
Why buy opal from ATL Luxury Jewelers?
For over 15 years, ATL Luxury Jewelers has sourced natural opal at our Snellville, GA showroom. We select stones for play-of-color brilliance, body tone, and structural soundness (no surface crazing), with documented origin where available.
Every opal piece includes lifetime cleaning (gentle method only), prong-tightening, and rhodium-plating (for white gold) at no charge — a policy we’ve held since 2009.
