What is pink opal?

Pink opal is a common opal: like every opal, it is made of hydrated silica, but it does not show the rainbow play of colour of precious opal. Its value lies in its soft pink tone, its gentle, milky appearance and its satiny polish. It is seen as beads, cabochons, pendants and small spheres.

Most of the market comes from Peru, notably the Arequipa region, where the opal is found in volcanic rocks of the rhyolite type. It is often sold as Andean opal, a term that more broadly describes common opals from South America, pink, blue or green.

The exact cause of its colour is not settled: some sources cite traces of manganese, others organic compounds (quinones) or a fibrous clay, palygorskite. The point remains debated. Its hardness is in the region of 5.5 to 6.5 depending on the source, and its water content is a few percent.

Traditional symbolism

Pink is the colour of tenderness in many cultures, and the stone inherits this: in contemporary tradition it is associated with gentleness, kindness towards oneself and affection. Esoteric shops often present it as a “soothing” stone. This is a symbolic image: its meaning is above all the one we give it.

Like classic opal, it is linked to the idea of sensitivity and emotion. Bear in mind that the tradition of pink opal is recent: the stone has only become common outside Peru in the last few decades, and there is no ancient lithotherapy about it.

How to use it

As a necklace or bracelet: its discreet tone goes with light outfits as well as with black.
In the bedroom: a small sphere or cabochon placed on a bedside table makes a pretty decorative object.
As a gift: a pink opal pendant is a simple idea for a birth, a birthday in October or a gesture of friendship.
In meditation: the stone held in the palm serves as an anchor for breathing calmly for a few minutes.

To combine it, consider rose quartz, harder and more classic for the heart, or rhodochrosite.

Care and cleansing

Softer than quartz, pink opal should be handled with care.

Wipe it with a soft, slightly damp cloth, then dry it.
No ultrasonic cleaners, household products, perfume or lacquer on the stone: its surface is porous and can dull.
Heat and prolonged sunlight: to be avoided (risk of dehydration and fine cracks, and possible fading of the colour).
Salt and soaking: to be avoided.
Store it separately, as it scratches on contact with harder stones (quartz, for example).

For symbolic cleansing, use gentle smoke, moonlight or selenite. See the cleansing guide.

Recognising real pink opal

Pink is an easy colour to imitate, and several cases exist:

Natural pink opal: irregular tone, variable translucency, sometimes veinlets or paler patches. This is what one expects from a natural stone.
Pink glass: uniform, very smooth, sometimes with small bubbles visible under a loupe. Lighter or heavier than expected depending on its composition.
Dyed chalcedony or quartz: a very bright, saturated colour, with concentrations of dye in the cracks.
Dyed opal: common opals can be coloured; a very intense pink with no variation is a warning sign.

The only real guarantee is the seller's openness about the nature of the stone. See also our guide to choosing.

How to choose

Choose a piece with no visible cracks, an even polish, and a colour you enjoy in daylight (electric light changes it). Beads that are well drilled, with the same tone from one end of the necklace to the other, are a sign of care; perfect, total uniformity, on the other hand, should raise doubts.

In terms of price, pink opal remains an accessible stone. An expensive piece is not necessarily better: a well-polished cabochon is preferable to a large, carelessly finished block. For everyday wear, a mounted piece (ring, pendant) protects it better than a bracelet exposed to knocks.

Frequently asked questions

Is pink opal a real opal?

Yes, when it is natural: it is a common opal, hydrated silica, without play of colour. Be wary of glass imitations or dyed stones presented as natural.

What is Andean opal?

It is the trade name for common opals from South America, mainly Peru: pink, blue or green, milky, and without play of colour.

Is pink opal fragile?

It is softer than quartz (about 5.5 to 6.5) and contains water: it is sensitive to knocks, strong heat and chemicals. Handled with care, it keeps well.

Why has the colour of my pink opal changed?

Prolonged exposure to heat or strong light can fade certain tones, and cosmetic products can dull the surface. For a dyed piece, the colour may also weaken over time.

Can it get wet?

Brief contact with lukewarm water does no harm, but do not let it soak, and dry it straight away.
