General Questions

To ensure the quality of gemstones, avoid chemicals, such as perfumes or cleaning products, that may damage, fade or stain your gemstones or metal, do not wear gemstones in the shower, while swimming, or during other activities that expose them to water, and do not leave gemstones out in direct sunlight to prevent fading.

To clean gemstones: Use a soft cloth to polish and clean metals and gemstones. Avoid water and harsh chemicals. Do not use materials that may scratch the gemstones. To clean black lava stones: Saturate a soft cloth in a solution of a ¼ cup water and a ¼ cup rubbing alcohol. Cover lava stones with cloth for 3-4 hours, re-saturate cloth as needed. Avoid placing water on metal jewelry to avoid tarnishing or discoloration. 

At Zehnaria, we aim to use natural gemstones when possible. This means that gemstone colors, shapes, sizes, and patterns may vary for each individual bead – making each bracelet unique. Bracelets are also taken in a professional light so gemstone colors may vary. Last, the number of gemstones in each bracelet will differ according to size, as a larger bracelet will require more gemstones and vice-versa.

If you have a specific look you are trying to achieve, please leave these in the "notes to seller" so that we can do our best to make your experience great. 

Over 95% of our gemstones are natural. Natural gemstones form in the earth, unlike synthetic gems which are man-made under laboratory conditions. However, due to the rarity and uniqueness of colored, natural gemstones, some gemstones have been enhanced using commonplace techniques such as heat treatment, protective coatings, dyeing, and irradiation to improve the sustainability, durability, availability and appearance (i.e. color, clarity) of gemstones. Take care to not scratch or damage gemstones with water, harsh chemicals, perfumes, lotions, or temperature changes.

We recommend oils be added to black lava stones (1-2 drops undiluted) while bracelet is placed on top of a paper towel to absorb excess. Please allow time for the stones to absorb the oils (typically 5-15 minutes). Excess oils can be removed by dabbing with a paper towel. Please note, depending on the color of the oil, essential oils can stain white lava stones.

Alternately, oils can be diluted prior to being added to lava stones, and then they can be added to the bracelet while on your wrist and they can touch the skin with no problem. Please see the dilution chart in About Us section for recommended topical dilutions. 

Since our start, we have produced over 1,000 bracelets using elastic cord. This cord is designed to handle a 7lb test for stretch and each bracelet is quality tested before we mail it out.

In this time, we have only had 2 bracelets damage can occur during and after transit from our business to your home. We understand that situations occur beyond our control and we hope that our customers will be understanding if these rare occurrences happen.

If your bracelet breaks from normal use & proper care within the first 6 months, please message us and we are happy to help remedy the situation. After 6 months, contact us & we can restring for a small fee. Thank you for giving us the opportunity to make your experience great!
