Bixbite (red beryl): one of the rarest minerals, buy with caution

← Back to Guide to stones

Bixbite, or red beryl, is a variety of beryl in a deep red, coloured by manganese. Extremely rare, it comes almost only from Utah; cheap offers are suspicious.

What is bixbite?

Bixbite is the old name for red beryl (red beryl), an extremely rare variety of beryl (Be3Al2Si6O18) coloured by trivalent manganese (Mn3+). Like the other beryls (emerald, aquamarine, morganite, heliodor), it is hexagonal and hard: 7.5 to 8 on the Mohs scale. It forms small raspberry-red crystals, rarely more than a few centimetres long.

It was discovered in 1904 by Maynard Bixby in the Thomas Range, Utah. The mineralogist Alfred Eppler named it “bixbite” in 1912. The name was later abandoned in gemmology because it caused confusion with bixbyite, a quite different mineral (a black manganese and iron oxide) found in the same place and also named after Bixby. Today it is therefore called “red beryl”.

The significant deposits are in the Wah Wah Mountains of Utah, where red beryl occurs in rhyolite, a volcanic rock. It is also reported in New Mexico. Its rarity is extreme: the Utah Geological Survey has estimated that one red beryl turns up for every 150,000 diamonds. A two-carat stone is said to be as rare as a forty-carat diamond.

Cheap bixbite: what is it?

Given this rarity, beads, cabochons or cut stones sold as “bixbite” or red beryl at modest prices cannot be natural gem-quality red beryl. The possible cases are:

  • a synthetic red beryl, made in a laboratory by a hydrothermal process with cobalt and manganese;
  • a red glass or a dyed quartz;
  • another red stone (garnet, spinel, rubellite, synthetic ruby);
  • morganite or pink beryl, sometimes presented as “bixbite” through loose use of the term;
  • bixbyite, a black mineral unrelated to beryl.

This is not an accusation against sellers, but a fact: a stone of this rarity is sold with a laboratory certificate.

Traditional symbolism

Its rarity and deep red associate it, in modern books on crystals, with passion, vitality, courage and uniqueness. It is presented as an “exceptional stone”.

These ideas are modern conventions: the stone was not known before the 20th century and has no ancient tradition. No study shows any effect of the stone on energy or happiness.

How to use it

  • As collector's jewellery: rare cut stones set in a ring or pendant. The hardness of 7.5 to 8 is suitable; red beryl, however, is often heavily fractured because it formed in a volcanic rock.
  • As rough crystal: small crystals on their rhyolite host rock, for collectors.
  • As a learning reference: bixbite is a good example of the caution a rare stone demands when buying (certificate, provenance).

Care and cleansing

  • Cleaning: lukewarm water, mild soap, soft brush. Dry.
  • Sunlight: the colour is stable; still, avoid intense heat.
  • Knocks: the stones are often fractured; avoid knocks and thermal shock.
  • Ultrasonic cleaners and steam: avoid (frequent fractures).
  • Symbolic cleansing: smoke, sound, moon (guide).

Recognising a genuine red beryl

Only a laboratory can distinguish natural red beryl from synthetic red beryl. No home test is reliable. See real or fake stone, how to read a treated-stone label and our commitments: we do not present as natural red beryl a stone that is not one.

How to choose

If you are drawn to rarity, insist on a laboratory certificate and proof of provenance. If your budget is modest, turn to other, more accessible beryls (morganite, aquamarine, heliodor) or to another red: garnet, spinel, ruby. To look after all your stones, read our guide.

Frequently asked questions

What is the difference between bixbite and bixbyite?

Bixbite is red beryl, an extremely rare gemstone. Bixbyite is a black manganese and iron oxide, unrelated to beryl. The name bixbite was abandoned to avoid confusion.

Why is red beryl so rare?

It forms only under very particular geological conditions (rhyolite, presence of manganese), and gem-quality deposits are almost all in Utah.

Can you buy bixbite cheaply?

A low-priced offer cannot be natural gem-quality red beryl. It is often glass, dyed quartz, a synthetic or another stone.

Does synthetic red beryl exist?

Yes, made hydrothermally with cobalt and manganese. Only a laboratory can distinguish natural from synthetic.

Is red beryl hard?

Yes: 7.5 to 8 on the Mohs scale. But the stones are often fractured, so handle them with care.
