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.

please note: • Be aware that fine-gauge wire that is normally spooled may simply be wrapped and bagged, at our discretion, when ordered in lengths less than 5 ft.
• We strive to measure quantities ordered as closely as possible; however, due to manufacturing tolerances at the mill, please allow for a ±10% variance when ordering.
How To Understand Metal Hardness
Here's how to understand the difference between hard and soft wire hardness. Knowing how to choose the hardness best suited to your jewelry technique and design goes a long way toward achieving the professional result you want.
DEAD SOFT: Metal that is dead soft is in a relaxed state at the molecular level, so it is easy to bend, shape and hammer. The act of bending and shaping will gradually work-harden the metal--right up to the breaking point. Dead soft metal will not hold its shape if put under stress in structures such as hinges or clasps.
1/2-HARD: Metal that is half-hard has been worked a bit, tightening the grain at the molecular level. This metal is harder to bend and hammer, but it is still possible in some cases to shape the metal--it just takes more force. While still malleable, it will also hold its shape under a certain amount of stress; it is ideal for wire wrapped structures that will support other components. If you are fabricating an item that needs both strength and a thinner gauge, you would probably choose half-hard.
FULL-HARD: Metal that is tempered (or significantly work-hardened) will be difficult to bend but will hold whatever bend you put into it pretty stubbornly. This hardness is ideal for clasps or hinges.
SPRING-HARD: Metal thoroughly hardened will lose pretty much all of its malleability and will actually spring back into its original shape when bent by hand. This hardness is ideal for ear wires, jump rings and head pins.
The main thing to remember, too, is that metal hardness is changeable. If you start with dead soft and work it or stress it, you will harden it. If you start with hard metal and heat it (either by soldering on it or by deliberately annealing it) you will soften the metal--all the way back to dead soft, if that's what you want.
