Paraíba is the copper-bearing tourmaline with an electric, neon blue-to-green glow unlike any other gem. Its intense color and extreme rarity make it one of the most expensive colored stones.
Paraíba value is driven by the intensity of its neon glow, the origin, and its rarity in clean larger sizes.
From Paraíba state, the original source: the most intense electric blue-green, in tiny supply and at the very top of prices.
Larger, often cleaner copper-bearing stones with vivid neon color; the main source of bigger Paraíbas.
Copper-bearing tourmaline with good neon color, generally more affordable than Brazilian.
Six main criteria determine the price per carat. It is their combination that sets the final value.
Everything: an intense, glowing neon blue-to-green (the "electric" or "swimming-pool" look) is the most valuable; weaker color drops the price quickly.
Brazilian Paraíba commands the highest premium; Mozambique and Nigeria are valued sources, usually at lower prices for similar color.
Most Paraíba is heated to enhance the neon glow (accepted). Origin is confirmed by lab analysis of copper content.
Brazilian stones are often included and small; cleaner larger stones (Mozambique) are prized. The neon color can offset some inclusions.
Brazilian Paraíba above 1–2 ct is extraordinarily rare, so price per carat escalates dramatically with size.
A lab report confirming copper-bearing ("Paraíba-type") tourmaline and origin is essential at these price levels.
Paraíba's signature is an intense, almost glowing neon blue-green caused by copper — no other tourmaline matches it.
The more vivid and saturated the glow, the higher the price; the look is often described as "electric" or "swimming-pool" blue.
Brazilian Paraíba is the original and most expensive, but typically small and included.
Mozambique produces larger, cleaner stones; for equal color, Brazilian origin still commands a strong premium.
Geographic origin can be a strong prestige marker that weighs on value.
