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.

This 14/20 yellow gold-filled square wire offers a matte finish rather
than the usual mirror-bright finish. If you polish this wire, use extra
care to avoid damaging or removing the bonded surface layer of karat
gold. This gold-filled wire is packaged in coils and can be cut to any length that satisfies the system minimum. Orders must weigh at least 0.01 ozt.; if you click 'Add to Cart' for a quantity less than this, the cart will offer a prompt to let you know what the minimum for this item is.

please note: • Customers within the European Union: Please be aware that all gold-filled materials sold by Rio Grande are in compliance with EU regulation EN1811:2011. • 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 Protect Your Gold-Filled Material
Handling your gold-filled properly is essential to maintaining its good looks and its bright finish. Made with a substantial layer of gold bonded to a base metal core, gold-filled requires some special care to keep the gold layer intact and unmarred for your designs.
If handled properly, gold-filled should require only buffing. If you cut it, be careful not to damage the gold layer, particularly on corners and edges.
Gold-filled stock should be stored in a dry place. Tarnishing elements act very slowly in the absence of moisture.
Use tissue paper between stock to protect it against scratches.
Use a clean flannel cloth while working on gold-filled material.
Maintaining the condition of your tools is important. Keep cutters sharp; bending tools should be smooth.
Use a firescale retardant such as Stop-Ox II™ when soldering.
Clean the metal thoroughly.
How Gold-Filled Metals Are Made
Gold-filled, or gold overlay, is made by heat- and pressure-bonding a thin layer of karat gold to a brass (or other base metal) core. The "14/20" or "12/10" notation refers to the industry shorthand describing the resulting material. The first number is the karat purity of the gold used; the second number is the amount, by weight, of gold to the substrate material. "14/20" gold-filled material is made with 14-karat gold and the gold represents 1/20th (or 5%) of the total weight of the material. You may occasionally see other notations, too; each will inform you about the material's make-up. For example, "14/40" gold-filled is composed of 14-karat gold that represents 1/40th (or 2.5%) of the overall weight of the material.
• Karat gold covers the brass surface, making it tarnish-resistant. • The value of gold-filled is greater than gold-plated because gold-filled has an actual layer of karat gold, not just a microscopic film. • All of Rio’s gold-filled products meet federal quality standards. • Gold-filled jewelry is economical. Your customers enjoy the warm tones of gold at a fraction of the cost of pure gold.
• In 14/20 gold-filled, 1/20th (or 5%) of the total weight of the metal is 14-karat gold.
• In single-clad sheet, the gold layer is bonded to one side of the sheet of brass.
• In double-clad sheet, discs and other findings, the bonded gold is distributed to both sides of the brass (or base metal) sheet. In findings, the same amount of gold is distributed so as to cover all sides of the finding. This means that the thickness of the gold layer on each side will be half what it would be on single-clad sheet.
PLEASE NOTE: The weight of the gold relative to the substrate (brass or other base metal) will be the same in both single-clad and double-clad; on the single-clad sheet, all the gold is bonded to one side and, on the double-clad sheet, the gold is distributed so that half is bonded to one side and half to the other side. It is possible to manufacture double-clad gold-filled sheet so that both sides have the same thickness as a 1/20th single-clad sheet; in this case, the material would be 1/10 (10% by weight) of whatever karat gold is used--14/10 for example.
Guide to Metal Hardnesses
this guide helps explain the differences between hard and soft sheet and wire tempers. 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.
