Aquarius

Aquarius runs from January 20 to February 18 — a fixed air sign ruled by Saturn in traditional astrology and by Uranus in modern practice. Its stones are cool-toned and unusually durable, which makes it one of the easiest signs to buy a wearable piece for.

The Aquarius Stone Set

Aquarius is fixed air. Traditional pairing favours cool, clarifying stones rather than warm ones. The most consistently assigned:

• Amethyst — Mohs 7 violet quartz, the February birthstone and the most common Aquarius stone.
• Clear quartz — Mohs 7, the neutral amplifier and the most practical daily stone.
• Fluorite — Mohs 4, banded blue-green calcium fluoride; associated with mental clarity, but genuinely soft.
• Aquamarine — Mohs 7.5–8 beryl, the March birthstone, and the literal match for the sign's name.

Why Amethyst Leads

Amethyst is the stone most often listed first for Aquarius, for two reasons: February is Aquarius season, so the birthstone and sign stone coincide; and amethyst's traditional association with clear, unhurried thinking matches the sign's reputation for detachment. It also happens to be one of the most durable stones in the collection at Mohs 7, which is a happy coincidence rather than a design.

Choosing for an Aquarius

• Bracelet — amethyst in 8 mm; durable, versatile and easy to size.
• Necklace — clear quartz for someone who prefers not to wear colour.
• Pendant — fluorite if you want the blue-green banding, but include the care note: Mohs 4, no ultrasonic, no soaking.
• Ring — amethyst or aquamarine only. Fluorite rings will not survive.

Dates and Birthstones

Aquarius covers January 20 to February 18 in the tropical zodiac. January's birthstone is garnet; February's is amethyst. Anyone born in the first ten days of Aquarius season has garnet as a birthstone and amethyst as a sign stone — worth clarifying if you are shopping to a specific brief.

Gifting Notes

Aquarius is the sign most likely to ask what a stone actually is. Include the mineral name and hardness with the gift; it will be appreciated more than the wrapping.
