Quick Answer
What is December’s birthstone?
December’s birthstone is blue topaz. Vibrant sky-blue topaz — December's birthstone — symbolizes clarity, calm, and clear winter sky. Hand-set into rings, pendants, and earrings at our Snellville atelier.
About Blue Topaz — the December Birthstone
Blue topaz is one of December’s traditional birthstones — alongside tanzanite, turquoise, and zircon — and the most widely available of the four. Topaz sits at 8 on the Mohs scale, harder than aquamarine and durable enough for daily wear in rings, pendants, and earrings.
ATL Luxury Jewelers stocks blue topaz across pendants, stud and drop earrings, solitaire and halo rings, and bracelets set in 14K and 18K gold or platinum. Modern blue topaz is virtually all irradiated and heat-treated from naturally colorless or pale-blue rough — a stable, permanent, and fully disclosed treatment that produces the popular “Swiss blue” (vivid medium blue) and “London blue” (deep teal-blue) varieties.
Blue topaz pairs sharply with white gold or platinum, reinforcing the cool sky-blue palette. Yellow gold creates a warmer vintage feel. Tanzanite, turquoise, and zircon are December’s alternate birthstones — we stock all four. Tanzanite is more valuable and ranks higher for collectors; blue topaz offers the best size-to-price value.
