The term "conflict diamonds" refers to the diamond rough used to fund violent criminal insurgencies in several African countries.
The Kimberley Accord is a compact that regulates the sale and transfer of diamond rough to prevent the human destruction that conflict
diamonds cause. Rio Grande has long asked our suppliers to provide documentation proving the safe origin of the diamonds we buy.
You can be assured every diamond you buy from Rio Grande is certified “conflict-free” by both our strict standards and the Kimberley Accord.

PMC PRO™ silver clay is significantly stronger than Original PMC®, making it the ideal choice for rings, delicate designs and functional components such as clasps, hinges and prongs--anything that requires a bit more oomph! • Works just like other forms of PMC®, only better! You have longer working time with PMC PRO™--great to carve, easy to join. • PMC PRO™ can be worked with the same tools used for other metal clay; however, make sure to rinse or wipe them clean before switching clays. Priced per individual package; each individual package contains 50g of metal.
Composition: Metal powder (90% fine silver, 10% copper), water and organic binder Shrinkage: 15–20% Color: Gray Firing temperature: 1400°F (760°C) for 1 hour in a stainless steel firing pan, embedded in coconut shell–based activated carbon (make sure you have about 1/2" of carbon surrounding each piece; avoid using too much carbon, as this will reduce the temperature inside the container). For one or two small pieces, it is possible to fire at the same temperature and reduce the firing time to 30 minutes. For larger pieces and full loads, fire at the same temperature for 2 hours. Melting point: 1450°F (790°C) Density after firing: 9.5g/cm3 Size:

please note: PMC PRO™ must be embedded in coconut shell–based activated carbon inside a firing pan during firing. Carbon and firing pan are sold separately. PMC PRO™ has a strong adverse reaction to contact with aluminum. Do not use aluminum tools or allow your PMC PRO™ to come into contact with any aluminum object.
How To Finish PMC Designs
You have several options when it comes to finishing your PMC designs. Get a quick view of the various hand and machine finishing options.
HAND FINISHING: The simplest way to finish PMC® is to use your hands and some good, old-fashioned elbow grease.
• Polishing papers are rated in grits. The grit tells you how many particles per square inch the paper has; the lower the number, the more coarse the paper.
• Begin with a coarse paper (about 400-grit) and graduate to increasingly finer papers until you achieve the finish you want. Change the direction of the stroke when you change grits to see when the marks from the previous paper have been removed. Use adequate pressure so each grit paper can work effectively.
• A hand burnisher can be an alternative to using sanding paper. After firing, run the burnisher along the surface of the metal, moving in the same direction for each stroke, and overlapping strokes to avoid leaving drag marks.
MECHANICAL FINISHING: Use a mechanical polisher, such as a flex shaft, to create textures with less time and effort. They hold a variety of attachments, offering a range of application options. Most polishers accept a range of accessories.
• A foot-pedal control is an important accessory; it keeps your hands free to work and allow you to control the motor speed as you work, changing speeds as needed for each piece.
• A flex shaft reduces hand fatigue and strain; it allows you to hang the motor from a stand and work with a smaller, lighter handpiece.
• Mounted motors give you the convenience of hands-free operation and accept larger attachments; they are ideal for large or flat pieces and for higher production needs.

Explanation of Terms
The first three clays are 100% silver. PMC Sterling contains 92.5% silver with the balance copper.
The nonmetal content refers to water and binder.
In all clays, shrinkage occurs equally along the X-, Y-, and Z axes unless the clay is constrained or restricted. The degree of shrinkage is related to the amount of binder.
Some clays offer options that balance a lower temperature against a longer soaking time. See other charts for the relative merits of the other schedules. Always fire at the highest temperature and longest time possible.
This refers to the degree a sample can be stretched before it breaks. Relevance: A ring with a higher number can be sized by stretching.
Related to elongation, this measurement shows how much force is needed to break a sample. A higher number means the piece will be harder to break.
This is a measure of how much force is needed to bend a sample. The higher the number, the more rigid the piece will be. Relevance: A ring with a high number will not bend out of shape when worn.
Surface Hardness (Vickers)
This refers to a test that measures what happens when a point of specific size is pressed into a sample. Relevance: A high number here means the surface is hard; textures and details will not wear away quickly.
We can think of this as a measure of how tightly packed the crystals are. Generally the tighter the structure, the tougher the metal. In objects of a given size, a denser material will weigh more.
