*Radiance Level Disclaimer*

At GeoPulse Minerals, we use our own internal classification system to evaluate the light performance of Mexican Fire Opals.
This system is based exclusively on the intensity, stability and chromatic strength of the fire, play of colour, displayed by each specimen, as fallows:

Radiance Level I - Soft Glow
Gentle internal light with delicate colour movement.

Radiance Level II - Bright Glow
Noticeable radiance with stable brightness and defined flashes.

Radiance Level III - Intense Radiance
Strong, vivid fire with powerful colour response from multiple angles.

Radiance Level IV - Flame Radiance
Top tier. Maximum intensity, highly saturated flame-like play of colour and exceptional optical behaviour.

This scale allows collectors to immediately understand the visual strength and rarity category of each opal we present.

Radiance Level I - *Soft Glow*

Description:
A Mexican fire opal shaped naturally into a triangular form, displaying a gentle glow created within the volcanic cantera of Jalisco. This specimen reveals a small but vibrant window of colour, where soft amber lights shift toward brief flashes of green and red when the stone is turned under direct illumination. Although the radiance is subtle when compared to higher tier pieces, the internal scene is enriched by the presence of opal eggs which appear as rounded silica formations nestled inside the cavity. These natural structures add character, geological identity and a sense of depth rarely seen in smaller cantera opals.

The surrounding matrix remains intact and organic, with quiet tones of grey and white that frame the inner colours and emphasise the triangular silhouette. This is a piece valued less for intense fire and more for its mineral architecture, its internal formations and its unusual shape which appeals to collectors who appreciate the raw and authentic expression of Mexican opal formation.
