Mini Andean Blue Opal Point

Mini point of blue Andean opal with ocher matrix vein, hand-carved in our lapidary workshop from rough imported from Peru. Dimensions: 12.8×7.3×5.6 mm. An ocher-brown stripe crosses the front face and contrasts with the sky-blue turquoise of the opal. Stabilized with consolidating resin to prevent microfractures due to dehydration.

Piece Details

This Specific Piece

What distinguishes this point is the ocher-brown matrix vein that crosses its front face from top to bottom: the volcanic host rock that gave rise to the opal and which the lapidary has deliberately integrated rather than removed. The contrast with the sky-blue turquoise is immediate and gives this mini point a personality that more homogeneous pieces do not have.

It was carved into a point format to take advantage of the natural color distribution: the cleaner flanks frame the central vein. Oriented this way, each face shows a different interpretation of the same pattern.

How Andean Opal Forms

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 What Mounting It Works

• Bezel setting (925 silver or other precious metals) — hardness 5.5-6.5 requires side protection; the bezel protects the edges without covering the color
• Pendant with silver mounting — the mini format is versatile for delicate pendants; the matrix vein adds character without losing the clean turquoise color
• Wire wrap — an alternative for those who work with wire; the flat base facilitates secure attachment

Andean Opal in Lapidary Tradition

Spanish conquerors 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 inner communication — a stone for those seeking clarity in silence.

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 exhibits a homogeneous sky-blue color with subtle variations and possible matrix veins. Under magnification, the surface shows a resinous texture without crystalline structure. It is distinguished from dyed howlite by its more vitreous luster and the presence of natural matrix. 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, resulting from 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. Declaration based on lapidary observation; the piece does not include formal gemological certification.

What does resin stabilization imply for mounting?

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

How do you care for an Andean opal point?

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

Are the dimensions exact?

12.8×7.3×5.6 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.
