Handheld electric rotary tools or drills with grinding and polishing attachments can be used to grind down sharp edges and smooth rough rock surfaces. You can then polish out small imperfections by hand with emery cloth, stone polish, diatomaceous earth, or toothpaste or spray them with clear resin.
You need to know which rocks shine the best and the tools and materials you can use to polish them. The art of shaping, cutting, and polishing gemstones is known as lapidary and can be a gratifying hobby. However, using simple techniques, you can also elevate humble river rocks to lustrous beauty.

Know Your Rocks
Not all rocks become shiny with washing, grinding, sanding, and polishing, so you need to know which ones are worth the effort. Stones such as jaspers, agates, and petrified wood come in intricate patterns and striking colors and can be brought to a beautiful luster.
Aventurine and tiger’s eye are other rocks that can be made to shine. It is better to start with hard rocks that are very dense and without pores or voids.
Agate has a translucent quality that gives it an internal glow, and it polishes very brightly. It is abundant in stream beds and dry river washes and has natural decorative patterns such as bands, swirls, moss, lace, and plumes.
Jasper comes in various colors but is often white, gray, red, orange, brown, or yellow. It is more opaque than agate and also polishes nicely.
Rocks with tiny granules, like sandstone, are not worth polishing because they will never shine. Smooth, softer stones, like onyx, calcite, fluorite, limestone, and dolomite, are easier to polish by hand but can break easily.
Score the surface with a pocket knife to determine whether a rock will polish well. If the scrape mark is white or gritty, the stone will not become shiny, no matter how hard you work.
The Process of Cleaning Rocks without a Tumbler
If the rock is too large, you may want to cut it down to size using a hammer and a chisel. You can also use them to break off any unsightly protrusions.
Another more expensive way of doing this is to use a tile saw. This is an electronic machine with a blade over which water runs continuously. You can use it to cut rocks in half or in slices to expose their lustrous inner patterns before starting the beautification process.
First, clean the stones with hot, soapy water. Put them in a bucket and scrub off the dirt and grime with a scrubbing brush or old toothbrush, depending on their size. Soaking them for a few hours may help loosen the more stubborn dirt.
Once they are clean and dry, you need to use a grinding tool to remove the sharp edges and create a pleasing shape.
Depending on the size of the rock, you can use an electric handheld tool like a Dremel, an angle grinder, or another electric grinder. You can also fit attachments to electric drills for grinding.
Wear welding gloves, a face mask, and eye protection to avoid injury during the grinding and cutting stage. Secure the rock in a vice or clamp to prevent it from flying off and injuring you or someone else.
Next, you can begin the sanding process. Wet a coarse grit emery cloth or sandpaper and sand the edges until smooth. Some stones may already be smooth enough that you don’t need to use the coarsest grit on them first.
Also, softer stones can easily be damaged by too coarse sandpaper. Rinse the stone in water frequently during the sanding stage to remove the dust in fine crevices and scratches.
Sanding in different stages using finer and finer grits may be necessary.
After this comes the polishing stage. You can buy powdered stone polish at a hardware store or a rockhound or gemstone store. It comes in various colors that can alter the color of some stones, so be careful to choose one that closely matches the stone.
Dampen a small denim cloth and dip it into the polishing powder. Then, rub the rock with the fabric. Stones must be completely dry before you polish them.
A strip of leather can be used instead of denim cloth. Add the polishing powder to the leather, then buff the stone. You can also use diatomaceous earth to polish rocks.
TIP: It is often dirty when you find a rock in nature. So cleaning it before trying to make it look shiny is good. Acids are a great option for cleaning dirty rocks. Find out how to effectively clean your rocks in the article below:

Materials That Can Be Used To Make Rocks Shiny
Emery Cloth
Emery cloth, known as wet-dry sandpaper, is available at any hardware store. It ranges from coarse to fine grit, depending on the polishing stage.
You start by using the coarsest grit to remove all the rough corners and edges and work your way down to the finest grit for delicate polishing. It is better to use the one with a cloth backing than the one with a paper backing.
Repeatedly wetting the rock while rubbing helps eliminate excess material and prevents damage to the surface. The last polish should be done with a piece of felt containing aluminum oxide powder, which can be obtained from craft stores.

Car Wax
Some rocks are too soft for any kind of abrasive and should not be sanded. Car wax can make this kind of rock shine without damaging it. Before applying the car wax, wash the rocks well to remove any loose debris and dirt, and then dry them thoroughly.
Use a soft, moist cloth to apply the wax. Let it dry, and then gently rub the rock with a clean cloth. You can then apply a second coat for even more gloss.
Diatomaceous Earth
Diatomaceous earth (DE) consists of the remains of ancient, microscopic organisms called diatoms and looks like a powder. It is widely available at gardening stores and suppliers of products for swimming pools. It is a naturally occurring substance that is mildly abrasive. The advantage of using diatomaceous earth to polish smooth pebbles is that you do not lose as much rock from the surface.
Use food-grade diatomaceous earth as it contains the finest particles. Buff the pebbles with the diatomaceous earth to make them shine. You can also put the DE in a small plastic food storage box together with the rocks and shake it. The container should have five times as much DE as rocks.

Toothpaste
Use plain white toothpaste that claims to whiten teeth. The chemicals in it will remove stains from the rocks as well as it does from your teeth. Do not use colored toothpaste or gel toothpaste.
You can squeeze it onto a denim cloth and buff the stones with it or put it on a toothbrush and work it onto the surface. It removes contaminants that cloud the rocks and also increases their glossiness.
TIP: Making your rocks shiny is a similar process to making them look wet. In case you want to know what to do to make your rocks look wet check out the article below:

Jojoba Oil
Give those smooth river rocks a dazzling shine with jojoba oil! After a good scrub with soapy water, a few drops of the oil will bring out their natural luster. Remember, the shine will fade over time, so be ready to reapply every few weeks to keep your treasures gleaming.
The oil does not polish the rocks; it just gives them a shiny appearance that freshens them and makes them look wet.

Resin Spray
If your rocks are already worn round and smooth by mother nature, you can spray them with high gloss resin. Coat each stone with a light layer and let it dry.
Then, apply a second and third coat. Once they are dry, turn the rocks over and repeat the process. This makes them look wet, like you just picked them up from the beach or streambed.

Conclusions
There are several methods for making rocks shiny without a tumbler. To get a permanent shine, you can grind, sand, and polish them by hand using simple tools and materials available from most hardware stores. An even quicker method is to coat them with resin or other high-gloss sprays.
