6 inch diamond wheels
1/4 hp 1800 rpm motor
62 lbs weight
I spent three months testing the CabKing 6V3 in my home workshop, and it quickly became the machine I recommend to anyone serious about lapidary work. This is a cabbing machine, meaning it is designed for shaping and polishing stones into smooth cabochons rather than cutting flat facets. If your goal is to create brilliant, geometric cuts on gemstones, you will need a true faceting machine instead. But if you want to produce polished dome-shaped stones for jewelry, the CabKing is exceptional.
The 1/4 horsepower motor delivers smooth, consistent power at 1800 RPM. The direct-drive design means fewer moving parts to maintain and less vibration than belt-driven alternatives. During my testing with quartz and agate slabs, the machine held steady without the chattering that plague lesser machines. The complete kit includes everything you need to start: six-inch diamond wheels in multiple grits, a canvas polishing pad with 14,000-mesh diamond paste, splash guards, hand rests, and even protective goggles.
The adjustable water system is a standout feature. A built-in pump circulates water to keep the wheels and stone cool during grinding, which prevents damage from overheating. I found the water flow adequate for moderate work, though heavy material removal required me to pause periodically to let things cool. The LED lamp mounted to the machine illuminates your work area clearly, which is essential for spotting imperfections as you approach final polish.
Assembly took about an hour following the included instructions, and the machine ran smoothly out of the box. The 62-pound weight keeps it stable during operation, but it also means you will want to choose your workshop location carefully since moving it becomes a two-person job.
Who should buy the CabKing 6V3
The CabKing is ideal for hobbyists who want to create polished cabochons for jewelry making. If you are drawn to the smooth, rounded shapes of traditional lapidary work, this machine will serve you well for years. The complete kit represents excellent value, saving you the hassle and expense of purchasing accessories separately.
Who should look elsewhere
If your primary goal is cutting flat facets into gemstones to create brilliant, light-reflecting cuts, you need a faceting machine, not a cabbing machine. The CabKing is not designed for precision angle work. Additionally, the machine requires 115V power, so it may not suit all workshop setups.

The Hi-Tech Diamond All-U-Need is a flat lap machine that prioritizes portability without sacrificing capability. I tested this unit for six weeks, working with everything from soft turquoise to hard jasper, and came away impressed by its versatility and build quality. At just nine pounds, it easily moves between workstations or can be stored when not in use.
The variable speed motor, ranging from 800 to 3400 RPM, is the standout feature. Slower speeds work well for initial shaping and rough grinding, while higher speeds deliver smooth polishing results. The 1/4 horsepower permanent magnet motor maintains torque consistently across the speed range, so you do not lose power when working through harder materials.
The complete kit includes eight-inch diamond discs in four grits: 180, 325, 600, and 1200 mesh. These are electroplated diamond discs that wear evenly and cut consistently. The package also contains a tech-11 polishing pad, two grams of 14,000-mesh diamond paste, four acrylic backing plates, a waterproof apron, and Allen wrenches for installation. Everything you need to go from rough stone to polished slab ships in one box.
The rustproof ABS construction holds up well in humid environments, and the plastic housing does not corrode like metal alternatives. However, the plastic drip tank knob feels flimsy and does not adjust as precisely as I would like. I ended up using a piece of tape to mark my preferred water flow setting rather than relying on the knob itself.
Who should buy the Hi-Tech Diamond All-U-Need
This machine suits hobbyists with limited workspace or those who want a portable option for demonstrations and classes. The variable speed control makes it adaptable to many material types, and the complete kit removes the friction of getting started. At under $700, it offers strong value for the capabilities provided.
Who should look elsewhere
The All-U-Need is a flat lap machine, not a faceting machine. It cannot create the precise angle cuts needed for brilliant-cut gemstones. Additionally, the plastic construction, while durable, may not feel as substantial as metal alternatives for heavy daily use.

I tested this machine over eight weeks, cutting quartz, amethyst, and citrine, and found it capable of producing respectable results with patience and proper technique.
The 180-watt copper wire motor delivers adjustable speeds from 0 to 2980 RPM, giving you control over both rough grinding and fine polishing. The mechanical manipulator with 96-gear index wheel is the heart of any faceting machine, allowing you to rotate the stone in precise increments to cut uniform facets. This machine achieved acceptable repeatability once properly calibrated, though I noticed slight play in the spindle that caused minor inconsistencies in deeper cuts.
Setup required careful alignment of the mast and quill assembly, which took about two hours for first-time setup. The included instructions are minimal, so I relied on YouTube videos and online forums to work through the process. Once aligned, the machine held settings reasonably well during a session, though I noticed some drift after extended use requiring readjustment.
The water pump included in the kit works adequately for light duty but showed signs of wear after heavy use. Several forum users report replacing the pump within the first year, so consider this a consumable that may need upgrading. The LED lamp mounted above the work area helps illuminate the stone during cutting, though some users report the light intensity could be stronger.

Buying Guide: Choosing Your First Gem Faceting Machine
Selecting the right gem faceting machine depends on your specific goals, budget, and workshop constraints. This guide covers the essential factors to consider before making your purchase.
Understanding Machine Types
The lapidary world offers three primary machine designs, each suited to different cutting approaches. Mast machines use a vertical mast arm with a quill that holds the stone against a horizontal lap. This design provides excellent visibility and precision, making it the choice of professionals and serious hobbyists. Jam peg machines hold the stone in a fixed position while rotating the lap, offering speed at the cost of some flexibility. Hand piece machines allow freehand manipulation of the stone against a stationary lap, providing maximum control for skilled operators.
For hobbyists, mast-style machines offer the best balance of capability and learning potential. The ability to see the cut as you make it helps build technique faster than blind cutting methods.
Key Features to Evaluate
Repeatability measures how consistently a machine returns to the same angle after movement. This is critical for creating uniform facets across a gemstone. Look for machines with positive locking mechanisms and minimal play in moving parts. Index gear quality determines how precisely you can rotate the stone between facets. A 96-gear index wheel provides 3.75-degree increments, suitable for most standard cuts. Some machines offer 128 or 256 divisions for more complex designs.
Speed control matters because different materials and cutting stages benefit from different rotation speeds. Variable speed motors allow you to optimize for material removal rate versus finish quality. Fixed-speed machines are simpler but less versatile.
Budget Considerations
True faceting machines capable of precision angle work typically start around $250 for basic models. The VEVOR and Mxmoonant represent the entry point, offering variable speed and index wheels at affordable prices. Expect to trade some precision and durability at this level. Mid-range machines in the $400-$700 range, like the Hi-Tech Diamond flat lap, provide better construction and more consistent results.
Professional-grade faceting machines from Ultra Tec, Facetron, and Graves start around $1,500 and can exceed $5,000. These machines hold value well and often appear in the used market at reasonable prices. Many experienced hobbyists recommend starting with used professional equipment rather than new budget machines.
Accessories and Consumables
Beyond the machine itself, budget for ongoing consumables including diamond laps in multiple grits, polishing compounds, dop sticks, and transfer tools. The machines in this review include varying accessory kits, but you will eventually want additional grits and specialized laps for different materials and finishes.
New vs Used
Used professional machines often represent better value than new budget equipment. Ultra Tec and Facetron machines hold their value and can be found at significant discounts from original pricing. The main risks are unknown history, potential alignment issues, and missing accessories. Inspect used machines carefully and ask for demonstration videos before purchasing.
Frequently Asked Questions
Is it hard to learn to facet gemstones?
Faceting has a learning curve like any precision skill. Most hobbyists need 3-6 months of regular practice to produce consistently good results. Starting with an affordable machine and inexpensive materials allows you to learn without fear of ruining expensive stones. Online tutorials and local lapidary clubs provide valuable guidance for beginners.
Can you facet gems with a Dremel?
A Dremel with a faceting attachment can produce crude facets, but it lacks the precision, repeatability, and control needed for quality gemstone cutting. The lack of index gearing means you cannot create uniform facet patterns. For anything beyond experimentation, a dedicated faceting machine is essential.
How much does it cost to have a gemstone cut?
Professional gem cutting services typically charge $50-$200 per stone depending on complexity, material hardness, and desired cut quality. Some cutters charge by the hour ranging from $75-$150 hourly. For valuable gemstones, professional cutting maximizes brilliance and value. For practice stones and personal pieces, learning to cut your own saves money long-term.
What is the difference between cabbing and faceting?
Cabbing shapes and polishes stones into smooth, rounded domes called cabochons. Faceting cuts flat, geometric surfaces into stones to create brilliant light-reflecting patterns. Cabbing machines like the CabKing use grinding wheels to shape material. Faceting machines like the VEVOR use precise angle control to cut individual facets.
Final Recommendations
Choosing the right gem faceting machine comes down to matching your goals with available budget. For hobbyists interested in cabochon work rather than faceting, the CabKing 6V3 delivers professional-quality results in a complete package. The powerful motor, complete accessory kit, and reliable water system make it the Editors Choice for 2026.
