JINGLING 7 inch Lapidary Blades Thin Diamond Saws Blade Trim Rock Gemstone Cutting Saw Jewelry Tools for Stone

4.5 out of 5 Could be a little cheaper probably but the profit vs cost/precision of this blade is worth it. 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 to work with safely. The blade does not say it is rated to use for quartz and for those who don't know. Quartz is very hard. If this blade can stand the test of cutting these geode agates without smashing them open. I would say the description for this item is accurate. This blade is for TRIMMING and fine shaping softer smaller minerals. It will not last forever, it is thin and the blades diamond layer is only about 3mm. A small Dremel blade would be cheaper and has more diamond cutting space if you are looking for a cheap alternative. If this blade seems like it is worth the money for a specific project, trust me, it is great for small pieces. If it works for quarts when it is not graded for it, it will work for trimming smaller softer material for a while if you are patient and using the right tools. TLDR This blade is great if you can read the description, are cutting the right material, have the right tools, knowledge and patience to utilize the blade.

By far my favorite blade to cut agates with! I have always hated losing so much material when using a standard blade. This thin blade cuts amazing!

I gave it four stars because of the price and ease of use. It is a very basic easy to use lab dairy blade but will not last long. This is not what you're going to use to cut a bunch of lake Superior agates and expect your blade to still act like new. But it's perfect for trimming and softer rock, will work on quartz but we recommend softer stone doing a lot of cutting.

This is complete trash i have tried 3 cuts ruinned all 3 put my cheap blade back on and as worn out as it is it still cuts 100 times better dont try and save money and buy one of these they are terrible rite in the trash with this one if i had spent more id ask for money back but at this point not worth the trouble

After rejecting more than on lapidary saw and more than one tile saw, I got this blade to go with an $85 Skil wet tile saw. I am working with (overly expensive?) opal simulants, and thus needed accurate 2mm slices from relatively sizeable pieces of rough. The Skil has a very effective "fence" to guide the rough (better than the vices on most lapidary saws!), and this super-thin blade remained rigid and consumed minimal material. I realize most tile cutters may not need to be so miserly with their materials, but in any case this is a thin, rigid, and stable blade and is a great value if such features are important to you.

I used the saw blade for cutting rocks. I've cut many types of Thunder Eggs, Agates, Jaspers, Quartz...you name it I've probably cut it. I have tried NUMEROUS brands and types of blades in the past 2 years and BY FAR THIS IS THE BEST for the money! I don't know what other people were cutting that gave this blade a bad rating...or perhaps it could be a quality control issue by the manufacturer... but I returned other more expensive blades and ordered more of this blade and hope the ones arriving today are as wonderful as this first one!

Very well made and works perfectly

The diamond coating does not last long. The blade is very thin, which is what I wanted however it doesn’t get through the rock. I purchased it for which is Quartz. 2 inch thick. We’re probably work well on soft stone just not something as tough as courts.
