What Are the Pisces Stones and Birthstones?

By Digital Towns Crystals ยท Last reviewed October 7, 2026

Short answer: the traditional zodiac stone for Pisces is amethyst, according to the list published by the gem expert George F. Kunz in 1913. Modern crystal traditions keep amethyst and often add moonstone and sea-blue aquamarine. Because Pisces runs from about February 19 to March 20, people born under the sign can also use the February birthstone, amethyst, or the March birthstones, aquamarine and bloodstone. Zodiac stones are a tradition rooted in astrology, not a property of the stones.

When is Pisces?

Pisces, Latin for "fishes", is the twelfth and final sign of the zodiac. Under the tropical zodiac used in Western astrology, the sun passes through Pisces from about February 19 to March 20; the exact dates shift slightly from year to year. It is a water sign, along with Cancer and Scorpio, and a mutable sign. Its symbol, two fishes joined by a cord, is traced in classical interpretations to the ichthyocentaurs, sea creatures who aided Aphrodite when she was born from the sea.

What is the Pisces zodiac stone?

Zodiac stones and birthstones are different lists. Birthstones follow the calendar month; zodiac stones follow the astrological sign. In his 1913 book The Curious Lore of Precious Stones, George Frederick Kunz gave a stone for each sign, and for Pisces that stone is amethyst.

Amethyst is the violet to purple variety of quartz, 7 on the Mohs scale. Its name comes from the Greek amethystos, "not intoxicated", from the old belief that it protected against drunkenness. It is also the February birthstone, so February Pisceans have the same stone for sign and month.

Which stones are linked with Pisces today?

Modern crystal shops and guides often name these stones for Pisces:

  • Amethyst: the traditional stone, and the most popular modern pick. In crystal traditions it is associated with calm, clarity, intuition and spiritual awareness.
  • Moonstone: a feldspar with a soft, floating glow. It has one of the longest histories of any gem in folklore, associated with lunar deities and, in Hindu mythology, said to be made of solidified moonbeams. Its watery glow suits a water sign.
  • Aquamarine: blue to blue-green beryl whose name comes from the Latin for seawater. Ancient mariners believed it would calm the waves, a natural match for the fishes. It is also a March birthstone.

These modern pairings vary from source to source. They are traditions and personal choices rather than a fixed rule.

What are the Pisces birthstones?

Because Pisces spans two months, people often use the birthstone of their birth month as well:

  • Born February 19 to February 29: the February birthstone is amethyst, also the traditional Pisces stone.
  • Born March 1 to March 20: the March birthstones are aquamarine and bloodstone; see the March guide.

What do Pisces stones mean in tradition?

Pisces is a water sign pictured as two fishes, and its modern crystal picks lean toward watery colors and calm meanings: violet amethyst, glowing moonstone and sea-blue aquamarine. Amethyst is associated with calm and clarity, moonstone with intuition and the moon, and aquamarine with the sea.

These are traditions and beliefs. Astrology has been recognized as pseudoscientific since the 18th century, and there is no scientific evidence that zodiac signs or the stones linked with them affect personality or events. People enjoy zodiac stones as personal symbols and gifts.

How do people use Pisces stones?

  • As jewelry: an amethyst or aquamarine ring, or a moonstone pendant, makes a popular birthday gift.
  • As a desk or bedside stone: an amethyst cluster or a moonstone tumble kept nearby as a personal reminder.
  • In meditation: as a focus object, as described in the meditation guide.
  • As a set: amethyst with aquamarine covers both of the sign's months.

How do you choose a Pisces stone?

  • For a traditional choice, pick amethyst, the Kunz zodiac stone and February birthstone.
  • For a soft glow, pick moonstone.
  • For sea blue, pick aquamarine, a March birthstone.
  • For jewelry worn daily, aquamarine, at 7.5 to 8 on the Mohs scale, and amethyst, at 7, are durable. Moonstone, at 6 to 6.5 with poor toughness, suits pendants and earrings better than rings.

How do you care for Pisces stones?

  • Amethyst: warm, soapy water; keep it out of strong sunlight, which can fade some amethyst.
  • Moonstone: warm, soapy water, and protect it from knocks, which can crack it.
  • Aquamarine: warm water, mild soap and a soft toothbrush; ultrasonic and steam cleaners are usually safe if the stone has no fractures or liquid inclusions.
  • Bloodstone: warm water and mild soap.
