What is Tourmaline?
Tourmaline is not a single mineral, but actually a group of complex minerals with different chemical compositions. The tourmaline group includes elbaite, dravite, schorl, and other closely related gemstones. The most common and valuable form of tourmaline is elbaite.
Tourmaline crystals form in a wide array of colors due to their complex chemistry. The most sought-after tourmaline colors are hot pink, emerald green, neon blue, and vibrant bi-color combinations. Other popular shades include purple, yellow, orange, red, and black.
In addition to its kaleidoscopic colors, tourmaline is valued for its durability. It ranks 7 to 7.5 on the Mohs hardness scale, making it suitable for daily wear. Tourmaline also has a trigonal crystal structure that can exhibit the pyroelectric effect of generating an electric charge when heated.
Metaphysical Properties of Tourmaline
In crystal healing traditions, each color of tourmaline is believed to have different metaphysical effects. For example, pink tourmaline supposedly promotes compassion, tenderness, and unconditional love. Green tourmaline is thought to enhance creativity and balance the heart chakra.
Whether or not you subscribe to these mystical beliefs, it’s easy to see why tourmaline is treasured for its symbolic properties. The variegated colors represent life’s infinite possibilities, while the pyroelectric quality embodies dynamic energy.
Factors Impacting Tourmaline Value
Several criteria determine the value and price of tourmaline gems or jewelry:
- Color – Vibrant neon and bi-color tourmalines fetch much higher prices than pale or brown stones. Unique color combinations are especially prized.
- Clarity – Eye-clean, transparent stones with no visible flaws are preferred. Cloudiness, fractures, or inclusions decrease value.
- Cut – Finely cut faceted tourmalines that maximize color saturation and brilliance command higher prices.
- Carat Weight – As with other gems, larger tourmalines are exponentially more rare and valuable. Premium is placed on stones over 5 carats.
- Treatment – Completely natural, unenhanced tourmaline is ideal, while stones with color diffusion treatment are worth less.
- Source – Fine tourmaline can come from Brazil, Africa, or North America. Specific locales like Paraiba, Brazil produce the rarest neon blues.
- Demand – Increased consumer desire for brightly colored tourmaline drives costs up. Trends influence which shades are most sought-after.
These factors mean high quality untreated tourmaline over 2 carats may cost $500 per carat or more. More common commercial grade tourmaline sells for $50 to $200 per carat.
Pros of Buying Tourmaline
There are many potential benefits to purchasing tourmaline:
- Dazzling Color – Tourmaline provides a rainbow of brilliant hues not found together in any other gem.
- Durability – Its hardness and toughness allow tourmaline to be worn daily without damage.
- Investment Potential – Rare types like Paraiba tourmaline have seen huge value increases recently.
- Sentimentality – The metaphysical meaning can make tourmaline a personalized, meaningful gem for some.
- Versatility – Tourmaline works for all jewelry styles from vintage to modern. Its color pops in both white and yellow metal settings.
Cons of Buying Tourmaline
On the other hand, there are a few drawbacks to consider:
- Cost – Significant sized high-quality tourmaline usually carries a steep price tag. Many buyers are priced out of the premium market.
- Treatments – Pervasive heat treatment and other enhancements lower value for collectors of untreated gems.
- Rarity – Extraordinary tourmaline is challenging to source, even at high prices. Availability is very limited.
- Softness – While not fragile, tourmaline does require some care to prevent chips, scratches, and abrasion over time.
- Personal Taste – Its saturated rainbow colors are bold, which may not appeal to those with more subdued style.
For gem enthusiasts who appreciate brilliant colors and unique stones, tourmaline can be a worthwhile addition to a jewelry collection. The unparalleled play of light in tourmaline is captivating. But stylish, durable tourmaline does not come cheap – you’ll pay a premium for large clean stones. For some buyers, the expense outweighs the benefits. The decision depends on your budget and personal preferences. With its alluring hues and cosmic flair, tourmaline makes a meaningful statement piece for collectors with selective taste.
