Every detail of the ObsidianQuad 4-Piece Set is built to outlast delicate boutique clasps and gimmicky plastic smart bands.
Stop guessing which single width fits everyone. Every order includes 4 independent circular strands—lava rock, faceted cubes, glossy spheres with gunmetal rings, and micro-matte beads—ready to stack or split 4 ways.
Weighing 68 grams across the set, the interplay of mirror-polished black spheres, brushed metallic gunmetal spacers, and sharp 6mm faceted cubes pairs effortlessly with any watch or cuff.
Tested across 500 wrist-roll cycles, the multi-strand internal core glides over knuckles in 2 seconds with zero spring clasps to weaken, rust, or catch on wool sweaters.
The porous volcanic lava stone strand features natural micro-craters that lock in a single drop of essential oil, giving you a subtle, grounding scent at your desk or on flights.
Your order arrives with four separate circular bracelets: 8mm porous volcanic lava stones, 6mm semi-matte faceted cubes, 8mm glossy stone spheres with 3mm gunmetal spacers, and 4mm micro-matte round beads.
Roll the concealed elastic cord smoothly over your wrist in 2 seconds with one hand. Wear all 4 for a layered editorial stack, split 2-and-2 as a couple, or let 4 friends each claim their favorite width.
Dab a single drop of cedarwood, sandalwood, or lavender oil onto 2 porous lava beads. Allow 60 seconds to absorb for clean, 24-hour personal aromatherapy with zero skin residue.

Why 4 Textures Beat 1 Matching Chain: In any friend group or couple, no two people dress the exact same way. By combining four distinct black silhouettes—from minimal 4mm micro-matte beads to bold 8mm lava rock and gunmetal-accented spheres—everyone gets a piece they actually want to wear daily, while still sharing the same cohesive obsidian palette.
Built for 24/7 Desk, Gym & Travel Wear: Delicate boutique chains weaken at the clasp and snap on coat sleeves, while $130 smart bracelets die every 72 hours. The ObsidianQuad uses solid stone, porous volcanic rock, and a multi-strand concealed elastic core that requires zero maintenance.
Sizing & Break-In Guide: Resting inner circumference measures 18.5cm–19.5cm, engineered for adult wrists between 6.2 and 7.8 inches. Out of the box, the cord is tensioned slightly snug so that after 48 hours of natural settling, it rests securely above the wrist bone without sliding over your hand.
Free 5–7 Day US Shipping: Every order ships free with full tracking and delivers in 5 to 7 business days.
30-Day Trial: Try it at home for 30 days risk-free. Need help? Email us anytime at support@buycosari.com.
2-Year Warranty: If anything goes wrong within 2 years, we replace it free of charge or refund your order in full.
No 0.8mm links to snap on sweaters and no weak spring-ring clasps that slip off during your commute. Just solid stone and high-tensile concealed cord.
At $29.99 for all 4 bracelets, you spend $7.50 per wrist instead of paying $114+ per person at a boutique jeweler or $130 for two plastic Bluetooth bands.
Every set is backed by our 30-day money-back trial and a full 2-year replacement warranty if any strand ever stretches out or breaks.

Lay out all 4 black stone and lava textures—let each friend pick their favorite width, split 2-and-2 with your partner, or keep all 4 to stack.
Slide the concealed elastic strands smoothly over your knuckles in 2 seconds flat. No tiny lobster clasps or second pair of hands required.
After 48 hours of wear, the cord settles cleanly to your wrist contour—giving your group a durable, understated anchor through work, travel, and workouts.
I've had this set for a full year and still love it. Everything has held up really well, and I wear the smallest matte micro-bead strand almost every day. The elastic is still solid.
Four of us split these during a February trip. We each chose a different style: lava rock, faceted cubes, glossy spheres, or the tiny matte beads. The stretch cord settled comfortably after a few days without becoming loose.
I highly recommend this set. I picked up the four-pack on a trip and split the black stone and lava bracelets with friends. It ended up being my favorite souvenir because we each still wear ours.
I wear two strands from the set daily, usually the faceted cubes and glossy beads with the gunmetal spacers. Both have held up with zero issues from the concealed elastic. Very happy with them.
These completely changed how I wear bracelets. My partner and I share the matching pieces, which feels surprisingly meaningful. I switch between all four black textures, and a drop of essential oil works nicely on the porous lava stones. They've also been very durable.
My best friend and I split the set, and we both wear our bracelets every day. It's a simple little reminder of each other that doesn't feel overly sentimental.
I had doubts after reading so many mixed opinions about matching bracelets, but these have been great for us. During a packed workday, looking down and seeing the matching black stones makes me feel connected to my partner. I genuinely recommend them.
Highly recommend. The black stone spheres have a satisfying weight, the gunmetal spacers look clean, and the matte cube beads add just enough texture. They feel much more substantial than I expected.
Thin chain bracelets always worry me because they can catch on something and snap. That's exactly why I chose this sturdy beaded set. There's nothing delicate to snag, and it has handled constant daily wear really well.
My last bracelet lasted about a year before the clasp weakened and kept slipping open. I switched to this set because there are no fragile metal clasps. I just roll the matte or glossy stone strands over my wrist and go.

Yes. Every single box includes all 4 separate circular bracelets: (1) the 8mm porous volcanic lava rock strand, (2) the 6mm semi-matte faceted cube strand, (3) the 8mm glossy black stone sphere strand with metallic gunmetal spacers, and (4) the 4mm micro-matte round bead strand.
All 4 bracelets are completely independent strands. You can divide them across 4 friends ($7.50 per wrist), split them 2-and-2 with your partner, or stack all 4 on one wrist for a layered look.
The concealed high-recovery elastic cord fits wrists from 6.2 inches to 7.8 inches (18.5cm–19.5cm resting circumference). They are tensioned slightly snug out of the box on purpose—after 2 to 3 wears, the cord relaxes by about 2mm so it molds comfortably to your wrist with zero baggy looseness.
Simply place 1 to 2 drops of your favorite essential oil onto 2 or 3 of the porous black lava stones and let it soak into the micro-craters for 60 seconds before rolling it onto your wrist. The porous rock holds the aroma for up to 24 hours.
No. The natural lava rock, polished stone beads, and sealed non-reactive gunmetal alloy spacer rings contain zero cheap copper plating, leaving your skin completely clean even during workouts.
Every order is protected by our 30-Day Group Fit & Daily Wear Money-Back Guarantee plus a 2-Year Elastic & Stone Replacement Promise. If you aren't thrilled with the weight, fit, or look, return the set within 30 days for a full refund.
