*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 follows: 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 IV - *FLAME RADIANCE* Description: Born within the volcanic grounds of Magdalena in Jalisco, this Mexican Fire Opal reveals a vivid inner world shaped by ancient heat. The creamy matrix gently frames a core of intense colour, where reds and molten oranges gather in glowing chambers reminiscent of slowly moving embers. Beneath the polished cabochon surface the fire seems to expand and contract, giving the stone a living quality that shifts with even the slightest movement of light. When illuminated from behind the specimen transforms completely. Its interior ignites into a molten panorama that evokes the incandescent heart of a forming planet or the silent glow of a volcanic cavern. The chromatic saturation becomes strikingly powerful, revealing the full strength of its Flame Radiance classification. This behaviour creates a dramatic geological scene in miniature where light travels through the stone as if filling a chamber of liquid fire. Every nuance of its internal architecture contributes to its expressive identity. Colours rise through translucent windows, forming layers of ember and gold that echo the geological origins of the opal. It is a specimen that does not simply display colour but releases it with a depth that feels elemental.

No filters, colour enhancement, or artificial saturation were applied. The lighting setup uses a calibrated 5500K light source, which replicates neutral daylight and reveals the true tones and clarity of the mineral. Under weaker or more yellow indoor lighting, colours may appear slightly different, which is normal and expected. The purpose of this setup is to present each specimen exactly as it appears in balanced natural daylight, allowing buyers to appreciate its authentic colour and lustre without distortion.
