Best For
This blade is best for hobbyists working with smaller, expensive gemstones like turquoise or opal where material loss must be kept to a minimum.
Pros and Cons
Pros:

2. Delta Diamond Gemking 8-Inch Lapidary Saw Blade for Precision Cutting Gemstones, Agate, and Geodes, 5/8″ Arbor
This blade is a step up for those who need to tackle denser stones like agate. The notched rim is a clever feature that keeps things cool during the cut. Knowing how to tell if a diamond saw blade is dull is key when working with these professional-grade notched rims.
Key Features That Stand Out
- ✓ Ultra-thin notched rim enhances coolant flow to the cutting surface
- ✓ Premium diamond concentration for clean, precise cuts with minimal chipping
- ✓ Designed specifically for wet cutting with water or cutting oil
- ✓ Sturdy 8-inch diameter handles larger rough material than standard trim blades
Why We Recommend It
We love the Gemking series because it balances durability with precision. The notched rim helps pull coolant into the cut, which prevents the blade from overheating when slicing through hard agates or geodes. It feels much more professional than basic plated blades.
Best For
This is the perfect choice for intermediate rock hounds who are moving on to harder materials like Brazilian agate or smaller quartz geodes.
Pros and Cons
Pros:
- Excellent coolant flow thanks to the notched rim design
- Very long-lasting compared to cheaper alternatives
- Can handle much harder stones without losing its edge quickly
- Produces very straight, accurate slabs
Cons:
- Requires a dedicated wet saw setup for safe operation
- More expensive than basic multi-pack options

Customer Review: Very impressed with the smooth finish it leaves on my geodes.
3. Delta Diamond Gemking 14-Inch Ultra-Thin Notched Rim Lapidary Blade for Gemstones, Agate, and Large Geodes
If you have larger geodes or big slabs to cut, this 14-inch blade is a solid pick. It offers professional-level results for large-scale slab work. Despite its large size, it maintains an ultra-thin profile to save material.
Key Features That Stand Out
- ✓ Massive 14-inch diameter for cutting large specimens and geodes
- ✓ Ultra-thin notched rim design for improved coolant circulation
- ✓ High-grade diamond grit for fast and clean slicing
- ✓ Robust core prevents wobbling during deep cuts
Why We Recommend It
We recommend this for big projects because finding a 14-inch blade that doesn’t waste massive amounts of stone is rare. This blade keeps the kerf thin, meaning you get more slabs out of your expensive rough material. It is a workhorse for larger slab saws.
Best For
This blade is best for users with large slab saws who need to cut big pieces of petrified wood or large geodes without massive kerf loss.
Pros and Cons
Pros:
- Capable of handling very large rocks that smaller saws can’t touch

Cons:
- Requires a high-powered slab saw to operate safely
- Heavy and can be difficult to mount for beginners
Customer Reviews
Customer Review: Works like a charm and cuts agate really well.
Customer Review: I was worried about the thinness on a 14-inch blade but it holds up great against hard stone.

This 5-piece set of 7-inch blades is perfect for those who do a lot of trimming. They are thin enough for precision but strong enough for daily hobby use. Having spares on hand means you never have to stop in the middle of a project.
Key Features That Stand Out

Pros and Cons
Pros:
- Comes with five blades so you always have a sharp one ready

Cons:
- Not intended for heavy slab cutting in hard agate
- Requires a gentle touch to avoid warping the thin core
Customer Reviews

Customer Review: For the price, you can’t go wrong. They cut clean and stay sharp for a decent amount of time.
5. Delta Diamond LGX Series 10-Inch Professional Lapidary Blade for Wet Cutting Gemstones, Quartz, and Petrified Wood
This professional-grade sintered blade is built for long life and smooth finishes. It is designed to handle tough materials like quartz and petrified wood without flinching. Sintered blades are the gold standard for durability in the lapidary world.

- ✓ Specifically engineered for wet cutting hard gemstones and wood
- ✓ 10-inch diameter provides a versatile cutting depth for various projects

Pros and Cons
Pros:
- Lasts several times longer than standard plated or notched blades

Customer Reviews
Customer Review: By far my favorite blade to cut agates with! I have always hated losing so much material when using a standard blade.
Customer Review: I use this blade to cut small .5-1 inch quartz geode agates. I am able to cut about 100 before the blade becomes too dull.
7. Jingling 6-Inch Diamond Lapidary Saw Blades, 0.53mm Thin Rim for Cutting Rocks and Gemstone, 5-Pack
This 5-pack of 6-inch blades offers a slightly thicker rim than the super-thin version, giving you a bit more durability. They are still excellent for saving material but can handle slightly tougher tasks. They are a great middle-ground for everyday rock cutting.

- ✓ Designed for materials like gaspeite and opals
- ✓ 0.5mm core thickness provides better stability during cuts
- ✓ Pack of 5 ensures you always have a fresh blade on hand

Best for hobbyists who want a balance between material savings and blade stability during general trimming of semi-precious stones.
Pros and Cons

Complete Buying Guide for Lapidary Saw Blades
Essential Factors We Consider
When you are shopping for lapidary saw blades, the most important thing to look at is the rim. Sintered rims last the longest because the diamonds are mixed into the metal. Plated or notched rims are cheaper but won’t last as many cuts. You also need to think about thickness. Thin blades save material but bend easily. Thick blades are strong but turn more of your stone into dust. Always check your arbor size to make sure it fits your saw, or look for blades that come with bushings.
Budget Planning
If you are a beginner, it is often better to buy a 5-pack of affordable trim blades. You will likely bend or dull your first few blades while learning. For those who cut hard agates every day, spending more on a single sintered blade is actually cheaper in the long run. Professional jewelry makers should always budget for ultra-thin blades to save money on expensive gemstones like turquoise and opal. While some ask if you can cut glass with a tile saw, remember that lapidary work requires these specialized diamond blades for the best results.
Final Thoughts
The right blade makes rock hounding much more fun. It prevents you from wasting hours of grinding and keeps your slabs straight. Take your time, use plenty of water or oil, and let the blade do the work. Never force the stone through the saw, or you will ruin even the best blade.
Frequently Asked Questions
Q: Should I use water or oil as a coolant?
A: Most small trim saws use water with a bit of additive to prevent rust. Larger slab saws almost always require a specialized cutting oil to keep the blade cool and lubricated for long cuts in hard rock.
Q: How do I know when my blade is dull?
A: If you have to push harder to make a cut, or if you see sparks, your blade is likely dull. You can sometimes “dress” a blade by cutting into a soft brick to expose new diamonds.
Q: Can I use these for dry cutting?
A: No. Lapidary saw blades are designed for wet use only. Cutting dry will overheat the rim, ruin the diamonds, and create dangerous dust that you should not breathe in.
Q: Will a 6-inch blade fit a 7-inch saw?
A: Usually yes, as long as the arbor size matches. However, you will lose a bit of cutting depth, and you must make sure the blade can still reach the coolant reservoir.
