Stone library / cultural browsing
Gemstones by zodiac sign
Western zodiac gemstone associations are a cultural browsing tradition — not a scientific classification, and not the same thing as a birthstone. Use these links to explore common zodiac-stone pairings, then open the individual guide for mineral facts, treatment disclosure, durability, and care.

Zodiac stones vs. birthstones
A zodiac stone is a cultural pairing with a sign of the zodiac, based on folklore and retail tradition. A birthstone is a gemstone assigned to a birth month, most often following the modern list standardized by jewelers and trade associations. They are different systems: a person born in July is a Leo by zodiac (often paired with peridot or citrine) but has ruby as their modern July birthstone. The table below lists the widely used modern birthstone for each month.
| Month | Modern birthstone |
|---|---|
| January | Garnet |
| February | Amethyst |
| March | Aquamarine |
| April | Diamond |
| May | Emerald |
| June | Pearl, Alexandrite, or Moonstone |
| July | Ruby |
| August | Peridot or Spinel |
| September | Sapphire |
| October | Opal or Tourmaline |
| November | Topaz or Citrine |
| December | Turquoise, Tanzanite, or Zircon |
Birthstone lists vary between traditions (ancient, traditional, and modern) and between regions. The table above reflects the widely used modern list; see the GIA birthstone reference for the authoritative breakdown.
