Birthstone Chart by Month and Zodiac Sign
Find your birthstone by birth month or zodiac sign, and see which ones can take a ring every day.
Your birthstone follows your birth month: garnet in January, amethyst in February, aquamarine in March, diamond in April, emerald in May, pearl in June, ruby in July, peridot in August, sapphire in September, opal in October, topaz in November, turquoise in December. Some months have two or three stones. Zodiac birthstones are a separate list, further down.

Birthstone chart by zodiac sign
Zodiac birthstones are a different tradition from birth months. A sign covers parts of two months, so your zodiac stone and your month stone can differ. There is no single official zodiac list. The most common chart gives each sign the stone of the month it mostly falls in. Older lists use bloodstone for Aries, agate for Gemini, onyx for Leo and carnelian for Virgo.
| Sign and dates | Stone |
|---|---|
| Aries (Mar 21 to Apr 19) | Diamond |
| Taurus (Apr 20 to May 20) | Emerald |
| Gemini (May 21 to Jun 20) | Pearl |
| Cancer (Jun 21 to Jul 22) | Ruby |
| Leo (Jul 23 to Aug 22) | Peridot |
| Virgo (Aug 23 to Sep 22) | Sapphire |
| Libra (Sep 23 to Oct 22) | Opal |
| Scorpio (Oct 23 to Nov 21) | Topaz |
| Sagittarius (Nov 22 to Dec 21) | Tanzanite or turquoise |
| Capricorn (Dec 22 to Jan 19) | Garnet |
| Aquarius (Jan 20 to Feb 18) | Amethyst |
| Pisces (Feb 19 to Mar 20) | Aquamarine |
Neither list is more right than the other. Use the month for a birthday gift, the sign if you follow astrology, or simply the color you like.
Which birthstones can you wear every day?
Hardness decides how a stone lives on a ring. On the Mohs scale, the lower the number, the more a stone needs a protective setting or gentler wear.
- Hardest, 8 and above: diamond (10), ruby and sapphire (9), alexandrite (8.5), spinel (8), topaz (8, but it cleaves).
- Middle, 7 to 8: aquamarine and emerald (7.5 to 8), garnet and tourmaline (7 to 7.5), amethyst and citrine (7). Emerald's toughness ranges from poor to good, so protect it from knocks.
- Softest, 7 and below: peridot (6.5 to 7), tanzanite (6 to 7), moonstone (6 to 6.5), opal (5 to 6.5), turquoise (5 to 6), pearl (2.5 to 4). They suit earrings or a pendant better than a ring.
Why do some months have several stones?
The first official US list dates from 1912, set by the National Association of Jewelers, now Jewelers of America. It was updated in 1952 (alexandrite, citrine, tourmaline, zircon), in 2002 (tanzanite for December) and in 2016 (spinel for August). Trade bodies still differ slightly: the American Gem Society adds sardonyx for August, GIA does not.
