Capricorn

Capricorn runs from December 22 to January 19 — a cardinal earth sign ruled by Saturn. The stones paired with it are dark, dense and structural, which matches the sign's reputation for patience and long horizons.

The Capricorn Stone Set

Capricorn is cardinal earth ruled by Saturn. Traditional pairing favours stones that are old, dense and unornamented. The most consistently assigned:

• Garnet — Mohs 7–7.5, the January birthstone, most commonly the deep red almandine.
• Black tourmaline — Mohs 7–7.5 schorl, dense and protective; the most durable of the set.
• Fluorite — Mohs 4, banded green-purple calcium fluoride, associated with structure and clear thinking.
• Smoky quartz — Mohs 7, a translucent grey-brown quartz that suits the sign's preference for understatement.

Durability, Ranked

Capricorn customers tend to want one piece they can wear forever, so this ranking matters:

• Garnet and black tourmaline (Mohs 7–7.5) — genuinely daily-wear. Garnet's main risk is that almandine can be brittle if heavily included.
• Smoky quartz (Mohs 7) — the safest single choice; neutral colour, quartz durability.
• Fluorite (Mohs 4) — soft, cleaves in four directions, and should not be worn as a ring. Bracelets are acceptable with care.

Why These Stones

Saturn's associations — time, discipline, structure, endurance — are why Capricorn's list skews to dense dark stones rather than bright ones. Garnet's name comes from granatum, pomegranate seed, for the deep red of almandine; it has been a talisman stone since the Bronze Age. The pairing is traditional rather than empirical, but the visual logic is consistent.

Choosing for a Capricorn

• Bracelet — garnet or black tourmaline, 8 mm; both handle daily wear.
• Necklace — smoky quartz is the understated choice.
• Pendant — fluorite, where its colour banding shows and the soft stone is safe.

Dates and Birthstones

Capricorn covers December 22 to January 19 in the tropical zodiac. December's birthstone is turquoise, zircon, tanzanite or blue topaz; January's is garnet. Garnet therefore serves double duty as both the January birthstone and the most common Capricorn stone.
