Complete Guide To Jade Carving

Video How to polish jadeWhat is Jade?Jade is an ornamental mineral mostly associated with its green varieties. In the jewellery trade, many opaque green stones are incorrectly named “Jade”. Jade has been mined and used centuries, but it was only in 1863 that a French mineralogist determined that there were only two minerals that could be referred to as ‘Jade’: Nephrite or Jadeite.Reading: how to polish jade

Jadeite

• Jadeite has about the same hardness as quartz (between 6-7 Mohs hardness).
• It is rarer and more expensive than Nephrite and may be a white-grey green, leafy green, blue or blue-green, emerald green, lavender, pink, red, orange, greenish-black or black.
• The translucent emerald green ‘Imperial Jade’ is globally considered the rarest and most valuable.
• Myanmar and Guatemala are the main sources of modern gem jadeite.

Nephrite

• Nephrite is slightly softer than Jadeite (between 6-6.5 Mohs hardness).
• Nephrite generally occurs in creamy white (known in China as “mutton fat” Jade), mid- to deep olive green, brown and black.
• Also referred to as New Zealand Greenstone.
• Canada provides the major share of modern nephrite Jade.

Jade Carving

What is Jade Carving?

Jade carving falls under the Hardstone Carving category – a form of artistic carving of predominantly semi-precious stones that incorporates both Jewellery making and Sculpture.

Why Choose Jade?

Apart from its cultural symbolism, jade is an excellent choice for crafts and jewellery making due to its unique colour, clarity, pattern and nearly indestructible strength. The very toughness of jade makes it ideally suited for fine, intricate carving.

What Can You Carve with Jade?

Jade is suitable for the creation of pendants, bracelets, rings, earrings, necklaces, and statuettes. Its hardness allows for the cutting of chains from solid blocks of stone, and even paper-thin designs are achievable. Jade has been a classic choice for the creation of plates, bowls, and vases for centuries.

Jade Carving Tools

Unless you have some Chinese bone, bamboo, and stone instruments to abrade your jade stone, you will have to embrace modern technologies to carve Jade.As Jade is rated between 6 and 7 on the Moh’s hardness scale, you will need a material rated at 10 to cut, shape and polish Jade. For this, Diamond tools are essential.

The 10 Essential Tools for Jade Carving

Safety Glasses and Dust mask (to protect against debris and dust)

High-quality Rotary tool with Flexible Shaft (such as a Dremel, Pendant Drill or Micro Motor.

Frame Saw and Diamond Wire Hand Saw Blades (for cutting)

Diamond Cutting Wheels or Diamond Slitting Discs (for cutting, shaping and outlining)

Diamond Burrs (for carving, engraving, grinding, de-burring and shaping)

Diamond Drills (for drilling holes and diamond twist drills for enlarging holes – useful for bead making)

Polishing Wheel or Diamond abrasives such as hand pads or cloth (for polishing and buffing)

Polishing Compounds or rotary tool diamond polishers (for finishing)

Decent Bench Light (for enlightenment!)

Headband Magnifier (if you’re working on small scale items)

Permanent marker or Chinagraph Pencil (to trace the design onto the work piece)

How to Carve Jade/Jadeite

The carving of jade can be seen as a 3-step process:

Cutting the shape

Carving (Abrading) the details of the design

Polishing the surface

Jade Carving 101

• The work piece is cut to shape using diamond wire or a diamond cutting disc and ground to shape using diamond tools such as diamond burrs. Alternatively a pre-cut cabochon can be used and then carved. (For intaglio or seal engraving rings this would be ideal)
• Trace your design onto your work piece using the permanent marker or Chinagraph pencil.
• Using a rotary drill (a flexible shaft is highly advisable) and your diamond burrs, you can start carving your design into the work piece.
• Water must be used as a lubricant throughout the cutting and carving process.
• Any number of diamond burrs can be used to outline your design, the most popular being the diamond ball burrs.
• Diamond point burrs can be used to engrave intricate and filigree lines.
• diamond cone burrs and diamond wheel burrs will deepen outlines.
• Diamond cylinder burrs and diamond wheel burrs can be used to remove the background material.
• Diamond Nail Head Burrs are ideal for top faceting work.
• For drilling holes into the Jade, you will need to use diamond drill bits and diamond core drills.
• Intricate designs can be cut manually using a diamond wire handsaw.

Troubleshooting Tips when Carving Jade

• Diamond tools should never be run dry, as excessive heat will shorten their life cycle.
• Using water throughout as a lubricant will reduce Jade dust and keep your diamond tools running smoothly.
• Jade dust should never be inhaled – always use personal protective equipment such a dust mask or respirator.
• Investing in a flexible shaft for your rotary tool will ensure a comfortable grip and keep the rotary tool body away from the water.
• Both Jadeite and Nephrite often have interspersed hard and soft areas causing the classic “orange peel” appearance – Polishing with finer grades of diamond is the best remedy for this problem.
• Carving is a manual job and this means your body posture is vital.
• Invest in a headband magnifier as your designs are as intricate as your eyes will allow.
• Create ample room for movement at your work bench.

Dremel Carving 101

Simply insert and fasten your diamond cutting disc, diamond burr or diamond drill bit into the chuck or collet of the Dremel. (I recommend the Dremel Multi Chuck).

The flexible shaft allows for a comfortable grip and a distance between the rotating bit and the main body of the Dremel tool.

Select the appropriate rotation speed for the Dremel to match the surface and bit accessory and start carving. Helpful note: Diamond tools must be run at a slow speed to preserve the life of the tool and prevent the diamond grit burning off. (We recommend 5,000 rpm)

Be sure to lubricate the workpiece and diamond tool frequently with water.

Be sure to wear safety glasses and a dust mask while carving any material. wear finger tape to protect your fingers from cuts and abrasions

How to Polish Jade

Polishing jade is done using an abrasive and finishing off with a polishing compound.Jade polishing can be done with a mechanical work wheel or by the manual use of diamond hand polishing pads and cloths.

• Rotary tool with felt buffing pads attachments and diamond paste.
• Polishing Machines (Buffing Machines).
• Lapidary polishing machines.

Polishing machines are dressed with specific grit drums, discs or belts – ranging from rough to ultra-smooth.The process is finished by using a matching buffing felt pad and polishing compound.Polishing Jade 101:

Attach a 120-grit wheel, drum, disc or belt to your polishing machine.

Start with a light pressure and increase until you see sanding in progress.

Move the direction of the jade at least 90 degrees within every 15 seconds to curb gouges, chips and undercutting of the stone.

Change the sanding material to the next grit level and repeat the process moving from the 120-grit through 300, 600 and finishing up with the 1,200-grit material.

A buffing pad can be added to the polisher or you can use diamond hand polishing pads to continue by hand.

Apply the polishing compound during the buffing process – whether a bar or paste-type product.

Hold the Jadeite against the buffing pad, moving the stone in all directions until shiny and mirror-like.

A chrome oxide polishing compound or diamond polishing paste works best for Jade.

Polishers suitable for use on Jade:
