ROCK TUMBLING: WHERE TO FIND QUALITY ROCKS AND HOW TO EVALUATE THEM

Rock tumbling is a fun and rewarding hobby that lets you turn rough, jagged rocks into smooth, shiny gemstones. Whether you’re a beginner or an experienced rock tumbler, finding the right rocks is crucial to achieving the best results.

In this article, we’ll explore the different options for obtaining rocks, compare popular online retailers, and discuss criteria for evaluating the quality of the rocks you receive.

Finding Tumbling Rocks

There are several options for obtaining rocks for tumbling. The first and most obvious is to collect rocks from nature.

You can look for rocks on a nature hike or go rockhounding at a local quarry or mine. The advantage of collecting rocks yourself is that you can choose the exact type of rock you want and usually get them for free.

However, collecting rocks can be time-consuming and may not always yield the variety or quality you’re looking for. Another option is to buy rocks from an online retailer.

Online rock retailers offer a vast selection of rocks, ranging from rough to polished, and from common to rare minerals. They also provide the convenience of shopping from your home and the ability to browse and compare different options easily.

Some popular online retailers include The Rock Shed, Kingsley North, Gems By Mail, RockTumbler.com, and Amazon. Each of these retailers has its own pros and cons in terms of rock quality, mineral variety, rock size distribution, and rock hardness.

They also have an extensive selection of tumblers and tumbling supplies, making them a one-stop-shop for all your tumbling needs. However, while they have an excellent selection of equipment, their rock selection is more limited than other retailers.

Amazon is the world’s largest online retailer, and they offer a vast selection of rocks and minerals from various sellers. This option provides the convenience of shopping on Amazon and the ability to compare prices and reviews.

However, the quality of the rocks you receive may vary depending on the seller, and you may need to do more research before making a purchase.

Criteria for Choosing the Best Retailer

When choosing an online rock retailer, several evaluation criteria need to be considered. These include:

Rock Quality – The quality of the rocks is crucial to achieving good results.

Look for rocks with aesthetic minerals, well-consolidated microcrystalline minerals, and hard minerals. Avoid rocks with excess porosity or internal fracturing, as they may not survive the tumbling process.

Mineral Variety – Different rocks offer unique patterns, colors, and textures. Choose a retailer that offers a wide variety of minerals, including jaspers, agates, quartz, petrified wood, and more.

Rock Size Distribution – An ideal batch of rocks should have a range of sizes, including small, medium, and large rocks. Having a variety of sizes will ensure that the rocks tumble evenly and prevent jamming in the tumbler.

Rock Hardness – Harder rocks tend to polish better, making them ideal for tumbling. Look for rocks with a Mohs hardness scale of 6 or higher.

Tumbling Rocks Quality Comparison

Once you have received your rocks, it’s essential to evaluate their quality before you start tumbling. Here are some criteria for evaluating the quality of the rocks:

Aesthetic Minerals – Look for rocks with visible, eye-catching minerals.

The minerals should be contrasting, bright and distinct, and not blending into one another. Lack of Fracturing and Porosity – Check for signs of internal fracturing or excess porosity in the rocks.

Rocks with multiple fractures or weak areas should be avoided as they may break further during tumbling. Well-Consolidated Microcrystalline Minerals – Tumblers frequently aim to obtain a high polish from rocks.

Microcrystalline minerals, such as chalcedony and jasper, tend to polish better than coarser-grained minerals. Hard Minerals – Rocks with a Mohs hardness scale of 6 or higher will be more resistant to abrasion during tumbling, resulting in a smoother, shinier finish.

Scores and Comments for Each Retailer’s Batch of Rocks

After evaluating rocks from each retailer, we have summarized our findings below:

The Rock Shed – Good quality, but some of their rocks are expensive. Kingsley North – Excellent quality, but high prices.

Gems By Mail – Affordable prices, but some rocks may be broken or subpar quality. RockTumbler.com – Limited rock selection compared to other retailers, but excellent tumbling supplies.

Amazon – A vast selection of rocks and minerals, but the quality may vary depending on the seller. In conclusion, finding quality rocks for tumbling requires some research and evaluation.

Collecting rocks from nature can be a fun and rewarding experience, but it may not always yield the desired quality or variety. Online rock retailers offer a convenient and diverse selection of rocks, but it’s essential to evaluate their quality before purchasing.

By considering the evaluation criteria and comparing popular online rock retailers, you’ll be on your way to a successful rock tumbling experience. Mineral Variety: The Importance of Choosing the Right Beginner’s Mix for Rock Tumbling

A diverse beginner’s mix will not only make the whole process more exciting but also help you understand the properties of different minerals and how they react during tumbling. It’s vital to note that some rocks may be harder than others, so choosing the right beginner’s mix can help you avoid frustration and ensure success.

Rock Size & Distribution: The Importance of Choosing the Right Beginner’s Mix for Rock Tumbling

After selecting the right mineral variety, you must also consider the size and distribution of the rocks in your beginner’s mix. Rock size and distribution are essential factors because they determine how well each rock tumbles and how much tumbler media you need to use.

Importance of Rock Size and Distribution in a Beginner’s Mix

A good beginner’s mix must have a range of rock sizes, including small, medium, and large rocks, to ensure they tumble evenly. Having a variety of sizes also helps to prevent jamming in the tumbler, keeps the abrasive media from lodging between the rocks and helping ensure uniform polishing results.

Having a good assortment of rocks and minerals enables beginners to explore a broad range of minerals while learning about the properties of different minerals and how they react during tumbling.

A good range of rock sizes will ensure even tumbling and uniform polishing results. By comparing the beginner’s mixes from various online rock retailers, you can make an informed decision about which mix will best suit your needs and help you achieve your desired results.

Rock Hardness Similarity: The Importance of Choosing the Right Mix for Rock Tumbling

When selecting rocks for tumbling, it’s essential to consider the hardness of the rocks in a batch. The hardness of the rocks determines how well they’ll tumble, how long it will take to achieve a polished finish, and how much they wear or contaminate the tumbler.

Importance of Rock Hardness Similarity in a Batch of Tumbling Rocks

Having a batch of rocks with similar hardness is crucial because it ensures an even wear rate for each rock in the tumbler. Rocks that have vastly different hardness levels can wear at different rates, creating an unequal finish, or may cause damage to the softer rock material.

It’s also important to avoid any rocks that are too hard or too soft for your tumbler, as they can cause unnecessary damage to the tumbler or fail to polish correctly.
