*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 III - *INTENSE RADIANCE* Description: As the stone is gently rotated through different angles, this Mexican Fire Opal reveals an extraordinary and highly unusual chromatic dialogue. What at first appears calm and restrained quickly unfolds into a vivid internal landscape where electric green ignites against deep violet and flashes of blue and purple emerge from within the cavities. The colour does not sit on the surface; it lives inside the stone, activating selectively depending on orientation, light and depth, creating a dynamic experience rather than a static display. Set within a remarkably pale volcanic matrix, almost chalk white in tone, the opal’s internal windows act like natural apertures into its chromatic core. The upper cavity delivers the strongest visual impact, where a concentrated green glow expands and contracts as the angle shifts, bordered by cooler blue and violet tones that add contrast and dimensionality. Below, a secondary cavity behaves like a hidden chamber, an unexpected easter egg where flashes of purple and blue ignite intermittently, rewarding closer inspection and slower viewing. The absence of continuous flame sheets gives way to something more intricate and refined. This is not a stone defined by surface fire, but by internal revelation. Each cavity functions independently, responding differently to light, creating a layered optical rhythm that feels both rare and deliberate. The colour play remains stable and expressive without collapsing, maintaining clarity of hue even as the stone is turned. Formed within the volcanic environments of Jalisco, this specimen captures the quieter but more complex side of Mexican fire opal formation. It is a stone that invites interaction, revealing its full palette only to those willing to explore it from every angle, making it both visually engaging and intellectually rewarding.

This stone stands out through its refined internal structure, pale matrix contrast and layered chromatic behaviour. Its appeal lies in complexity rather than excess, making it particularly attractive to collectors who value nuanced optical phenomena and stones that reveal themselves progressively over time. Lapidary Interest: While already compelling as a natural specimen, the internal colour windows suggest interesting possibilities for careful artistic cutting. Any lapidary approach would need to respect the positioning of the cavities to preserve the green and violet interplay. The stone’s internal response offers strong potential for experimental cabochon or conceptual display cuts that emphasise depth and directional colour rather than surface brilliance. ————— Shipping and Handling: All orders are shipped by UPS express or National Express. • Dispatch time: within 1 to 2 business days after payment confirmation to catawiki • Transit time with Express service: up to 3 business days within europe and worldwide • A tracking number is always provided Photography and transparency: All photos were taken under controlled light conditions, carefully selected to reproduce the most accurate natural colour of each specimen. 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. Identification and ethics: All specimens offered are guaranteed natural and as described. Their origin and mineral identification are provided with the most accurate and reliable information available. Every effort is made to ensure that each piece is presented with full transparency, avoiding any misleading details regarding its nature, treatment, or provenance. Customs and import taxes: Any customs duties, import fees, or local taxes applied by the destination country are entirely the responsibility of the winning bidder. These charges are not included in the auction price or shipping cost and are determined by the buyer’s local authorities. Guarantee and resolution: Customer satisfaction is a priority.
