Frequently asked questions (FAQ)
What is aromatherapy jewelry and how does it work?
Our aromatherapy jewelry lets you enjoy the therapeutic benefits of pure essential oils on the go. Each piece features a porous volcanic lava stone that absorbs a few drops of your favourite essential oil. The scent gently diffuses throughout the day, supporting mood, relaxation, focus, or energy without overwhelming others around you.
How do I use my diffuser jewelry?
Apply 1–3 drops of essential oil directly to the lava stone. Let it absorb for a minute before wearing. The scent typically lasts 1–2 days depending on the oil, climate, and how much you apply. Reapply as needed.
Is it safe to wear aromatherapy jewelry every day?
Yes — absolutely. All our pieces are crafted from S925 sterling silver, a premium alloy that is 92.5% pure silver combined with copper. No nickel is added, making it naturally nickel-free, hypoallergenic for the vast majority of people, and suitable for sensitive skin and daily wear.
Can I layer different essential oils or switch scents?
Yes. You can layer complementary oils such as lavender and bergamot. To switch scents completely, let the current aroma fade over 1–2 days or gently clean the stone with a small amount of rubbing alcohol on a cotton swab, then let it dry fully before applying the new oil.
How do I care for and clean my diffuser jewelry?
Avoid water, sweat, lotions, and perfumes directly on the lava stone. Wipe metal parts with a soft dry cloth. To refresh the stone, apply a drop of rubbing alcohol to remove old oil residue, let it dry fully, then reapply your oil. Store in a cool, dry place away from direct sunlight.
What is the difference between lava stone and other diffuser materials?
Volcanic lava stone is highly porous with a naturally rough texture, which allows it to absorb essential oils efficiently and release scent slowly over 1–2 days. Compared to terra cotta or wood diffuser beads, lava stone is more durable, moisture-resistant, and holds oils longer without residue buildup — making it ideal for daily wear jewelry.
How long does the scent last on lava stone jewelry?
Scent typically lasts anywhere from 6 to 8 hours up to a full day, depending on the essential oil and your body heat. Lighter oils like peppermint fade faster than heavier oils like rose or sandalwood. To refresh, add 1 to 2 drops directly onto the stone and allow 1 minute to absorb before wearing.
Can I use fragrance oils instead of essential oils?
We recommend using only 100% pure essential oils. Synthetic fragrance oils can leave residue that clogs the stone's pores over time and may contain chemicals that cause skin irritation. Carrier oils like jojoba or coconut are also too heavy for lava stone — they will block absorption. Pure essential oils give the best performance and longevity.
Is aromatherapy jewelry safe during pregnancy?
The jewelry itself — S925 sterling silver and volcanic lava stone — carries no pregnancy risk. However, certain essential oils are not recommended during pregnancy. Always consult your doctor before using any essential oil while pregnant.
Will essential oils stain fabric or skin?
Pure essential oils applied to a lava stone pendant will not typically stain skin or fabric, as the oil is absorbed into the stone rather than sitting on the surface. To be safe, apply the oil and let the stone absorb it for 1–2 minutes before wearing, especially near light-coloured clothing.
What essential oil is best for focus at work?
Peppermint is the most widely used essential oil for mental clarity and sustained focus. Rosemary and lemon are also known for supporting concentration. ĀARJA's Focus essential oil blend uses peppermint as its primary ingredient, formulated for workplace use during long hours — it diffuses at a level noticeable to you but not disruptive to those around you.
How is ĀARJA different from other aromatherapy jewelry brands?
ĀARJA creates modern, elegant aromatherapy jewelry for people who want to carry the benefits of essential oils throughout their day — whether at the office, in transit, or at home. Every piece uses S925 sterling silver and consciously sourced volcanic lava stone — not plastic beads or synthetic materials. ĀARJA also offers its own line of pure essential oil blends (Calm, Focus, Balance) formulated specifically for wearable diffusion, not room diffusion.
What metals does ĀARJA use in its jewelry?
All ĀARJA jewelry is made from S925 sterling silver — an alloy of 92.5% pure silver and 7.5% copper. We do not use nickel in any of our pieces, making them hypoallergenic and suitable for people with metal sensitivities.
Can I wear ĀARJA jewelry while exercising?
We recommend removing the jewelry before high-intensity exercise. Sweat and moisture can reduce the stone's oil retention and, over time, affect the silver finish. For light activity, the jewelry can be worn — rinse the stone with clean water afterward and allow it to dry fully before reapplying oil.
