Celeste Blue Andean Opal Point

Sky blue Andean opal point, hand-carved in our lapidary workshop from rough imported from Peru. Dimensions: 22.5×5.4×7 mm. The translucent sky blue veil with ochre limonite inclusions characterizes this Andean opal in an elongated format, ideal for a pendant. Stabilized with resin to preserve its structure long-term.

Piece details

This particular piece

The visual reading of this point is that of a sky-blue veil with ochre limonite spots and flecks floating inside — inclusions of the original volcanic rock that the lapidary has preserved because they add depth to the color. The translucency is more pronounced than in other Andean opals, and under direct light, the blue gains warmth towards a blue-green hue.

The elongated format (22.5 mm in height with only 5.4 mm in width) makes this point a direct option for slender pendants or for those seeking presence without excessive bulk. Oxidized or polished 925 silver works especially well with this natural sky blue.

How Andean opal is formed

Andean opal forms in hydrothermal volcanic deposits in the Peruvian Andes (Acari region, Arequipa). Silica precipitates in rock cavities at low temperatures. Less porous than Ethiopian opal, it is still sensitive to prolonged dehydration; the resin penetrates the micropores without altering the color or surface appearance.

For which setting it works

• Bezel setting (925 silver or other precious metals) — hardness 5.5-6.5 requires side protection; the elongated format is ideal for obelisk-type pendant mounts
• Pendant with silver mount — 22.5 mm height gives presence without being bulky; sky blue with ochre inclusions works well in both oxidized and polished silver
• Wire wrap — an alternative for those working with wire; the length facilitates wrapping at the top

Andean opal in lapidary tradition

Spanish conquistadors brought Peruvian opals to Europe in the 16th century as a mineralogical novelty from the New World. Their sky blue color without iridescence distinguished them from Hungarian opal and made them prized as decorative carving material.

In crystal tradition, Andean opal is associated with serenity and fluid communication — a stone for those seeking calm in constant movement.

The symbolic properties attributed to minerals belong to cultural and historical traditions. They are shared for educational purposes, not as medical advice.

How to recognize genuine Andean opal

Genuine blue Andean opal presents a homogeneous sky blue color with subtle variations and possible ochre limonite inclusions. Under magnification, the surface shows a resinous texture without crystalline structure. It is distinguished from dyed howlite by its translucency and more vitreous luster. Dyed glass is heavier (~2.5 g/cm³ compared to ~2.1 for opal) and has no internal mineral inclusions.

Frequently asked questions

Is the blue color natural or dyed?

The sky blue color is the natural color of the mineral, a result of the interaction between hydrated silica and the volcanic environment. This piece is stabilized with resin (declared treatment), but the color has not been altered. No detectable color treatment. Statement based on lapidary observation; the piece does not include formal gemological certification.

What does resin stabilization imply for mounting?

The resin consolidates the micropores without changing appearance or color. The piece behaves the same as an unstabilized opal: we recommend a closed bezel and avoiding solvents, ultrasonics, and sudden temperature changes.

How to care for an Andean opal point?

Use a soft, slightly damp cloth for cleaning. Avoid solvents, ultrasonics, and prolonged heat. More information in our jewelry care guide.

Are the dimensions exact?

22.5×5.4×7 mm are the actual measurements of this piece. As it is hand-carved, there may be a tolerance of ±0.5 mm in any dimension.
