Elk antler is one of the materials I reach for most when a piece needs warmth and texture. It takes daily wear well, and the more you handle it, the better it usually looks. The care is simple once you know what the material is doing.
What is antler made of?
The Lasso (Elk Antler Crown Shed & Australian Black Opal Triplets Bolo Tie)
Antler is a type of bone, and bone is made up of two components. Hard mineral gives bone its structure. Collagen, the same kind of protein in skin and connective tissue, holds that mineral together and keeps the whole thing from being brittle. Antler has more of that collagen than ordinary skeletal bone does. That extra collagen makes the antler more flexible so it can take a beating without breaking.
Every year, elk shed their antlers and grow a new set. A dropped antler is called a shed. I try to eliminate waste as much as possible, so I like to use found antler sheds. Elk antler sheds are an ethical and sustainable material.
If you look at the end of a cut shed, you'll see two zones. The outside is dense and almost polished-looking. The inside is open and spongy. On a ring or a bolo tie, both can show at once. I also leave as much of the natural outer surface as I can, so there's often rough texture too. The dense outside is pretty forgiving. The spongy inside and the rough natural surface are where water and dirt settle if they get in.
Durability
The Crown Ring (Elk Antler & Brass Band)
Antler scratches easily, but it takes a knock very well. Scratching and breaking depend on two different properties.
Scratching depends on hardness. The Mohs scale ranks hardness from 1 to 10, and anything higher on the scale can scratch anything lower. Antler sits somewhere around 2 to 4. Steel is about 5.5, and most gemstones are even harder. Sand, a steel edge, and the stone on another ring will all mark it.
Breaking depends on toughness, which is how well a material holds together when it takes a hit. Antler is among the toughest hard materials any animal grows. Elk fight with these things. All that collagen lets antler absorb a hit and stops small cracks from spreading into big ones. So a scratch on antler is usually just a scratch, and banging a ring on a doorframe is not the catastrophe it would be for something brittle.
Moisture
Water
The real cracking risk for antler is water moving in and out of it. Antler takes on water the way wood does. When it gets wet, the collagen swells. When it dries, it shrinks.
Both the wood and the antler leave the studio finished in Odie's Oil, a hardwax oil that soaks into the surface and hardens there. It slows how fast water moves in and out, but it doesn't make either one waterproof. What matters is how long the antler touches the water. Washing your hands or getting caught in the rain is fine. The water is gone before it has time to matter. A bath, a swim, a hot tub, or a long session doing dishes is a different story. That's enough time for water to work into the spongy core. I give the same timing advice for wood in my wooden jewelry care guide.
The damage happens as a soaked piece dries. The outside dries and shrinks first, while the core is still wet and swollen. That stretches the outer layer around a core that hasn't shrunk yet, and the strain is what opens cracks. If a piece does get soaked, you don't want to dry it fast. I let it dry on the counter at room temperature. Normal house air dries it slowly enough for the core to keep up.
Heat
Heat speeds up that same drying. Even antler that feels dry holds some water, and heat pulls it out fast enough that the outside shrinks ahead of the core. A car dashboard in summer, a radiator, and a windowsill in direct sun all get hot enough to do it. A hair dryer on a wet ring is the worst case: a soaked piece, dried as fast as possible.
Aging
Antler darkens with handling. Where it's worn against skin, it slowly goes a warm brown, most of all on the rougher, more porous areas. That's patina, the same kind of change you see on worn wood, and I think it looks better than trying to keep a piece looking brand new. I go deeper on that in Patina: The Look Your Jewelry Earns Over Time.
Light moves the color the other way. Antler slowly yellows with age, and daylight bleaches it back. A piece you wear out in the world stays a little lighter. One that spends a long time in a drawer drifts toward yellow. Neither one means the piece is failing.
Sweat isn't a structural problem either. It can leave a little staining if it sits, so I wipe a piece with a dry cloth after a hot day and call it done.
Upkeep
Cleaning
Day to day, a soft dry cloth is enough. Dirt collects in the rough natural surface and the open pores of the core, so it's easier to wipe it off as you go than to dig it out later. I don't soak antler, since a long soak is what cracks it, and I don't scrub it, because scrubbing scratches a surface this soft.
Ultrasonic and steam cleaners are a bad fit as well. An ultrasonic cleaner is a small tank that vibrates jewelry clean in a warm bath of cleaning solution. The Gemological Institute of America says porous organic materials like ivory should never go in one, because the heat and the chemicals can damage them. Antler is porous and organic in the same way. Steam is heat and water at once, which is exactly the combination that cracks antler. Neither cleaner belongs near the wood on the same piece either.
If a piece gets past what a cloth can handle, bring it back to me. Reconditioning is free for the life of the piece.
Oil
If the antler starts to look dry or dull rather than just dusty, use the same mineral oil touch-up I recommend for wood in What Oil Should You Use on Wooden Jewelry?. Put a little on a soft cloth, wiped on, then wiped off. The Odie's finish is still there underneath. The mineral oil just refreshes how the surface looks.
Storage
If antler knocks around in a drawer with metal and harder stones, it will pick up scratches. A soft pouch of its own is the easy fix.
Museums handle antler with gloves and keep it out of direct light, because their goal is for it never to change. A ring's job is to be worn, so most of what antler does over years of wear is the good part: a warmer color, and a polished sheen where your hand rubs it.

If you're thinking about antler for a custom piece, book a consultation. I'm happy to talk through it.
