Pink Opal
Pink Opal — Soft Colour and a Gentle Presence

Pink opal appeals through its gentle appearance and shades ranging from delicate pale pink to deeper, more pronounced pink. Unlike opal known for changing flashes of colour, pink opal’s natural bodycolour, texture and pattern are at the heart of its beauty.
Some stones have an even colour; others combine white areas, veins and transitions between shades. Each stone offers a slightly different appearance that cutting and polishing can bring out.
Pink Opal: A Gemological Overview
| Property | Information |
|---|---|
| Material | Opal without play-of-colour — hydrated silica |
| Composition | SiO₂·nH₂O |
| Colours | Pale to deeper pink, sometimes with white |
| Mohs hardness | Approximately 5–6.5 |
| Refractive index | For opal generally: approximately 1.37–1.47; varies with the material |
| Specific gravity | Approximately 2.0–2.25, depending on water content and additional components |
| Characteristic appearance | Usually opaque to translucent, without play-of-colour |
These are general reference values for opal, not measurements of a particular stone.
Colour and Light
Opal is hydrated silica, without the ordered crystalline structure of quartz. Pink opal may also contain components that influence its colour and texture, so not all stones have the same composition.
Its beauty comes mainly from its shade and the way light meets its surface. A cabochon — a smooth, rounded surface — is particularly suited to displaying the colour and pattern, giving the stone a gentle lustre.
What Influences Quality and Price?
Shade, colour distribution, pattern and polish influence the stone’s appearance and value. Some prefer even pink colour that looks clean to the eye; others are drawn to natural transitions and patterns.
The condition of the material also matters. Cracks, cavities and weak areas may affect whether and how the stone can be cut and set.
Size alone does not indicate quality. A small stone with attractive colour and a good polish may suit a design better than a larger stone with a less appealing appearance.
Treatments and Identification
Pink colour alone is not enough to identify opal. Other materials can look similar, and synthetic opal and imitations also exist.
When examining the stone, it is important to establish whether it has been dyed, impregnated or otherwise treated. Such treatments, where present, may affect its value and how it should be worked.
Suitability for Setting
Pink opal can look beautiful in pendants and earrings, which display its colour and pattern while generally exposing it to fewer impacts.
It can also be set in a ring, but the condition of the stone and the intended wear should be considered. Its hardness is moderate, and it may be damaged by an impact or pressure during setting.
In custom design, we examine the stone and choose a structure that supports it, protects its edges and gives its colour a place in the design.
Sources Around the World
Peru is a familiar source of pink opal, including material from the Nazca area. Pink opal sources should be distinguished from those of other opal varieties, which are not necessarily the same.
Spiritual and Symbolic Meaning — Beliefs and Traditions
In contemporary gemstone symbolism, pink opal is associated with gentleness, compassion, love and emotional openness. Its soft colour can serve as a personal reminder of a close relationship, tenderness or an intention someone wishes to carry.
As a gift, it may gain meaning from the person who chose it and the story behind the gift.
These meanings belong to the realm of belief and symbolism. They can give jewellery personal significance, but they are not proven gemological properties or a promise of healing, protection or a change in health.
