Neon is a descriptive trade term rather than a species name. It is applied to stones whose colour appears to glow from within — a saturation so high, and a hue so pure, that the gem seems lit from behind even in ordinary daylight. This page gathers the varieties in our collection that genuinely earn the description.
The clearest examples are Paraiba Tourmaline and Cuprian Tourmaline, where traces of copper produce the electric blue-to-green tones most closely associated with the word. Alongside them sit Burma Ruby, whose chromium content can produce a strong red fluorescence that lifts the colour in sunlight, Zambian Emerald in its most vividly saturated chromium greens, and Chrysoberyl in bright, transparent yellow-greens.
When choosing between them, weigh three things. First, hardness and wearability differ across these species, which matters for rings worn daily. Second, neon character depends heavily on cut — a well-proportioned stone returns light through the crown rather than leaking it. Third, decide whether you want the cool copper-driven glow of tourmaline or the warm, fluorescent intensity of ruby. Each reads quite differently once set.
