When cutting rare and valuable materials, precision is a must, and our lapidary saw blades deliver. At Delta Diamond Products, we offer some of the best professional lapidary blades on the market. Our rock-cutting blades provide ultra-smooth cuts on gemstones, quartz, agate, geodes, petrified wood, jasper, and more. From hobbyists working on personal projects to professional lapidarists, these blades provide the best cut for every need.
What Are Diamond Lapidary Blades?
Diamond lapidary blades are the go-to tools when precision is a must — whether you're cutting gemstones, polishing minerals, or working on a rockhound project. What makes them special? It's all in the diamond-infused edge, which slices cleanly through hard materials like agate, quartz, and petrified wood while keeping waste to a minimum.
Their thin rims allow for smooth, accurate cuts, while removing as little material as possible so you are left with more finished material. Rock-cutting blades are used with water to prevent overheating when cutting soft, porous materials or with cutting oils like rockhound or other oils on denser, harder stones. Whether you're a DIY hobbyist polishing a prized geode or a professional lapidarist handling delicate gemstones, lapidary saw blades offer the durability and finesse needed to get the job done right.
Features and Benefits of Our Rock Cutting Blades
Our rock cutting saw blades are built for high-precision cutting and are ideal for handling delicate materials like gemstones, geodes, quartz, and petrified wood. These blades shine when it comes to projects requiring smooth, chip-free results. Below are the features that make these wet-use diamond rock saw blades a must-have for anyone working with precious materials:
- Precision Thin Rim Design: These blades have an ultra-thin rim that minimizes material loss, helping you achieve smooth, clean cuts with minimal kerf. Removing the least amount of material is essential when working with expensive or fragile materials like gemstones.
- Wet-Only Use: To prevent overheating and ensure a flawless finish, these blades are used exclusively for wet cutting. The water keeps the blade cool and reduces friction, making it easier to cut through softer, porous stones and glass​. For harder materials, rockhound oil, mineral oil or your favorite cutting oil is recommended.
- Durability and Longevity: Because they're designed to last longer than standard or plated diamond blades, our lapidary blades offer better value over time. In fact, Delta Diamond lapidary blades enjoy a 50% longer life than standard or plated diamond blades. They're built to withstand extensive use, ensuring fewer replacements and uninterrupted projects​.
- Versatile Applications: Whether you're a lapidarist working with fine stones or a rockhound slicing open geodes, these blades are perfect for various materials. They excel at both intricate detailing and in high-production environments, making them a versatile choice for anyone working with rocks and minerals​. Our lapidary blades cut gemstones, agate, quartz, geodes, jasper, and petrified wood.

How do I know which blade size is right for my project?
The size of the blade you need depends on the thickness and type of material you're cutting. Larger blades cut thicker materials, while smaller blades offer greater precision for delicate stones and intricate cuts. Always make sure to get the proper blade for your saw.
What type of maintenance do diamond lapidary blades require?
Regularly check your blade for wear, such as uneven segments or reduced cutting performance. Keep the blade clean by flushing it with water after use to remove debris and prevent clogging. Occasionally run the blade through a dressing stone to keep the blade cutting like new. Proper storage is also essential — ensure the blade stays dry to avoid corrosion or rust on the steel core.
Do these blades require a specific RPM setting?
Yes, each blade diameter has a recommended RPM range to ensure optimal performance and safety. Using the blade at speeds outside the recommended range can lead to overheating, reduced efficiency, or even damage to the blade and material being cut. To make it easy, we include our "Diamond Blade Recommended RPMs" table on each product page.
Why Diamonds Are Necessary in Lapidary Saw Blades
Diamonds are critical in lapidary saw blades due to their hardness and precision, making them ideal for cutting intricate materials like gemstones, quartz, and petrified wood. In these blades, small diamond particles are embedded within the metal rim, allowing the blade to grind through dense stones with accuracy and minimal chipping. Unlike traditional blades that slice through materials, lapidary blades use an abrasive process, where the diamonds wear away the surface of the material layer by layer. As the blade cuts, new diamond particles are gradually exposed, ensuring consistent cutting performance and a longer lifespan. This self-renewing process makes diamond lapidary blades the top choice for delicate and high-precision cutting tasks, where both smoothness and durability are essential​.
