Inside Outside Hoops (Litmus)
- Crystal mosaic set inside and outside the hoop — light finds it everywhere.
- Handcrafted in sterling silver by artisans in Guadalajara.
- 1¼ inch drop — sits close to the jaw, quietly confident.
Think about what litmus actually means — not the paper strip from chemistry class, but the older, stranger thing. Litmus comes from lichens. For centuries, dyers extracted pigment from organisms that clung to rocks and bark, creatures that were neither plant nor animal, that changed color depending on what they touched. The word itself became a metaphor for sensitivity, for responsiveness, for the moment something reveals its true nature under new conditions.
That interplay of color and transformation is what Mosaico Jewels channels in these hoops. Working from their studio in Guadalajara, their artisans set tiny crystals by hand — inside and outside the hoop — so that the color catches light from every angle, every direction. It is a technique rooted in the Mexican mosaic tradition, where small individual pieces create something far more alive than any single surface could. The result is a hoop that never looks quite the same way twice: shift your head, step into different light, and the crystals respond.
Sterling silver forms the structure, polished to a clean, cool finish that lets the crystal work do all the talking. At 1¼ inches, these sit close to the jaw — intimate enough for a Tuesday, striking enough for a night you want to remember. Each earring weighs 4 grams, giving them a grounded, quality feel without any drag. The ear wires are hypoallergenic, so sensitive skin is never part of the conversation.
That responsiveness — color shifting with light, inside meeting outside, the small thing that reveals more the closer you look — is what makes these more than hoops. It is jewelry that behaves the way litmus behaves: differently, depending on the moment.

COLOR THAT RESPONDS
The Mexican mosaic tradition turns small, precisely placed elements into surfaces that feel almost kinetic. Mosaico Jewels applies that philosophy to jewelry, setting crystals by hand so the color shifts and breathes with every movement.

Got questions?
We've got answers
Find fast answers about shipping, returns, and our unique jewelry.
How long does shipping take?
Most orders ship within one business day of placing your order — sometimes the same day. Economy shipping typically takes about a week via USPS, while standard shipping (Priority Mail) arrives in 2-3 business days. We're based in North Carolina, so East Coast orders tend to arrive a little faster. You'll receive a tracking number as soon as your order ships.
Will the jewelry fade or tarnish?
Our jewelry is made from a variety of materials, including sterling silver. Sterling silver will eventually tarnish, but you can slow that process by storing it in a small airtight bag or container, or in a special anti-tarnish bag. If it’s lost some shine, it can be gently washed with a soft cloth, warm water, and a drop of mild soap, such as blue Dawn. If you still see tarnish, use an anti-tarnish cloth. Do not use commercial jewelry cleaners unless they are specifically labeled safe for sterling silver. The best way to keep your sterling silver shiny is to wear it often! The more you wear it, the less tarnish you’ll see. And never wear sterling silver in the swimming pool or hot tub! Chlorine will cause it to tarnish almost instantly.
Most other metals don’t exactly tarnish, but they can get a little dull if they’re not worn. Washing with a tiny amount of mild soap is the best way to bring them back to life again. You can prevent this by putting on your jewelry last, after you apply hairspray or perfume, and don’t wear them in the shower or bath.
Genuine pearls do require extra gentle care. Don’t ever use commercial jewelry cleaners on them; you will almost certainly damage the nacre and destroy their unique sheen and iridescence. Be very careful about hairspray, cosmetics, and perfume, and absolutely never put them in an ultrasonic jewelry cleaner!
Can I return or exchange?
Yes. You have 30 days from receipt to return or exchange anything that isn't marked Final Sale. Items need to be in new condition. Exchanges ship free, with no minimum order required. Returns are refunded minus a $5 shipping fee (once per shipment, not per item). We don’t ever charge restocking fees.
Is your jewelry hypoallergenic?
Most of our pieces are hypoallergenic, but not all. You can filter to only show hypoallergenic pieces when browsing, and you will also see an icon on all pieces certified hypoallergenic and nickel-free by their makers.
Can I track my order?
Yes — as soon as your order ships, you'll receive a tracking number by email so you can follow it the whole way to your door.
What makes your jewelry different?
Honestly? Most of it comes down to Amanda. Every maker on this site has been personally researched and verified — she checks that pieces are genuinely handmade, by the person who claims to have made them, using the materials listed. These are small-batch pieces in sterling silver, gold-filled, and genuine gemstones, mostly made in the USA. They aren’t factory pieces, aren’t from resellers, and are not the same thing you'd find on a hundred other sites. When something sells out here, it often stays sold out.
