*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 II – Bright Glow** Description: From the volcanic landscapes of Jalisco, this Mexican Fire Opal presents a naturally triangular silhouette that feels sculpted by geology itself, with a smooth domed profile and a clean, well rounded polish that enhances its presence from every angle. The outer body carries warm cream to rose and iron rich tones, creating a natural canvas that frames the opal’s inner fire with striking contrast. At the heart of the stone, a vivid window opens into a glowing internal world where colour emerges in concentrated flashes. Bright green radiance appears first, sharp and electric, then shifts into a greenish violet nuance that glides across the inner pocket like a living pulse. These tones do not sit flat on the surface, they bloom within the opal’s depth, suspended in translucent honeyed layers that give the piece a sense of motion and dimensionality. The overall effect is intensely aesthetic and highly collectible, a refined example of Bright Glow material where the colour presence feels deliberate, intimate and beautifully controlled by the stone’s natural structure. Its triangular form amplifies that character, giving the piece an unmistakable identity and a strong visual signature that reads as both gemstone and miniature natural sculpture.

The triangular morphology is uncommon and instantly recognisable, while the Bright Glow radiance concentrated within the internal window offers a vivid, high impact signature. It is a piece that reads as both geological artefact and refined gemstone, making it a distinctive addition to any serious opal cabinet. Lapidary Potential: The stone is already shaped and polished in a way that honours its natural silhouette and preserves the internal radiance pocket as the centrepiece. Its best value lies in keeping the current form intact, where the triangular outline, dome and internal colour window work together as a complete visual composition suitable for high end display or for a bespoke jewellery concept that celebrates organic geometry. ————— Shipping and Handling: All orders are shipped by Portuguese National Shipping. • Dispatch time: within 1 to 3 business days after payment confirmation to Catawiki • Transit time with CTT service: between 5 to 7 business days within europe and worldwide, depending on destination national post. • 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.
