Blue tourmaline ,known to gemologists as indicolite,is one of the rarest and most coveted members of the tourmaline family. While tourmaline is widely known in its green and pink varieties, the blue is something else entirely: deeper, more complex, and far harder to find in large, clean stones. At the apex of the blue tourmaline world sits Paraiba tourmaline, a copper-bearing variety with an electric neon glow unlike any other gemstone on earth.
At Astteria, we source exclusively natural blue tourmalines and Paraiba tourmalines, setting them in 18K gold designs crafted for women who appreciate the rarest things. Here are our three finest blue tourmaline jewelry pieces - each a different expression of this extraordinary stone.
1. Blue Tourmaline Ring - 4.92 Ct. TW | $6,500
A near-5-carat natural blue tourmaline in a round cut - this ring makes its case through colour, not volume. The round brilliant cut maximises the depth of saturation in the stone, allowing the cool, inky blue to radiate from every angle. At $6,500, it represents an accessible entry into fine indicolite jewellery without any compromise on stone quality.
What separates a blue tourmaline ring from a blue topaz or aquamarine is color complexity. Indicolite carries a deeper, richer blue - sometimes with a subtle teal undertone - that neither topaz nor aquamarine can replicate. Finding a near-5-carat stone of this colour quality, clean and well-cut, is increasingly rare on the market today.

2. Natural Diamond and Blue Tourmaline Drop Earrings - 7.14 Ct. TW | $6,800
These drop earrings pair a 4.06 ct oval blue tourmaline main stone with 3.08 ct of diamond accents, set in 18K white gold. At 35mm in length they sit with real presence - not costume jewellery length, but statement fine jewellery. The oval cut is a deliberate choice: it elongates the stone's colour depth and gives the design an elegant, graceful movement when worn.
The pairing of blue tourmaline with white diamonds is a study in contrast. The diamonds do not compete with the tourmaline -they frame it, and amplify its saturation. This is design thinking that separates fine jewellery from decorative pieces. In tourmaline - a stone notorious for colour variation - sourcing a matching pair of this quality requires patience and a trained eye. Each pair at Astteria is hand-selected for colour consistency.
Tourmaline is the October birthstone, making these earrings a particularly meaningful gift for those born in autumn.

3. Natural Greenish Blue Paraiba Tourmaline Necklace - 23.96 Ct. TW | $165,300
This is not a necklace — it is a collector's object. The centrepiece is a natural 18.91 ct oval Paraiba tourmaline in an unmistakeable neon greenish-blue, flanked by 3.75 ct of natural sapphires and 1.30 ct of round brilliant diamonds, all set in 18K white gold. Total carat weight: 23.96 ct.
Paraiba tourmaline is categorically different from standard blue tourmaline. Its extraordinary glow comes from trace amounts of copper and manganese - a geological accident that produces a color no other gemstone can reproduce. The finest Paraibas were first discovered in Brazil's Paraíba state in the late 1980s, and now command per-carat prices that rival top sapphires and rubies. An 18.91 ct specimen of this quality is a museum-grade stone.
The decision to accompany the Paraiba with natural sapphires - rather than only diamonds - is a compositional choice of real sophistication. The deep blue of the sapphires grounds the electric energy of the Paraiba, giving the piece a layered depth that a diamond-only setting could not achieve. This is high jewellery design in the truest sense of the term.

Understanding the Blue Tourmaline Spectrum
Not all blue tourmaline is the same. Here is how to read the market:
- Indicolite - the standard blue-to-blue-green variety. Value is driven by depth of colour, absence of grey modifier, and eye-clean clarity. Large, saturated stones are rare.
- Paraiba tourmaline - a copper-bearing variety with a neon electric glow. The rarest and most expensive variety of tourmaline. Originally from Brazil; smaller deposits found in Nigeria and Mozambique. Identified by its unique fluorescence under UV light.
- Treatment - heat treatment is common in tourmaline to lighten or shift colour. Natural, unheated stones command a significant premium. All tourmalines at Astteria are natural.
When evaluating blue tourmaline jewellery, look for saturation depth, minimal grey modifier, eye-clean clarity, and quality of cut. A well-cut, saturated indicolite in a fine setting will outperform a larger, poorly cut stone every time.
