Learn About Forever Metals Product Tungsten Composition Below

84% tungsten and 16% carbon and nickel (No cobalt)

Tungsten Carbide is the overwhelming choice of material used in engagement band primarily extreme durability, permanent high polished brilliance, and is readily available. It is forged by combining tungsten with carbide powders and nickel, resulting in an alloy which is practically scratch proof and indestructible. The bands are then polished to a desired requirement with a diamond compound, resulting in a polish and shine that is long lasting. Tungsten Carbide is the perfect combination of unequalled strength and everlasting beauty. Learn more about Ceramic and Tungsten Carbide Jewelry.

CP GRADE TITANIUM RING COMPOSITION:

Commercially Pure Titanium T1 and T2

Titanium is a grey metallic element noted for its relative strength and lightweight properties. Not only is titanium durable but it has an incredible resistance to corrosion. Titanium is used instead of stainless steel, copper alloy, and other metals due to it being readily available and low cost. Titanium has the highest strength to weight ratio of any known element. With jewelry, titanium’s light weight translates into comfort. Titanium, being nearly inert, exhibits exceptional resistance to a broad range of corrosive attacks by saltwater, gases, acids and alkalis or any body chemistry. Forever Metals’ commercially pure (CP) titanium is 100% hypoallergenic and allergy free and will not produce skin irritation or discoloration. Titanium is also virtually non-magnetic, making it ideal for applications where electromagnetic interference must be minimized. Pure titanium is about as strong as steel yet nearly half the weight. Titanium’s outstanding strength-to-lightweight ratio and its incredible resistance to most forms of corrosion have been the primary historical incentives for utilizing titanium in the industry.

INLAY COMPOSITIONS:

ZIRCONIA CERAMIC RING and CERAMIC INLAY COMPOSITION:

Zirconia Ceramic Powder and Cementing Agents

The mixture of Zirconia ceramic powder with cementing agents creates the material to make beautiful ceramic rings. Ceramic particles injected into sealed molds and condensed with high temperature sintering creates the core ceramic ring. High precision laser cutting is the final process step, resulting in a reasonably hard and highly scratch resistant ceramic ring. Unlike the Tungsten Carbide ring however, the ceramic ring will crack under extraordinary forces. Ceramic rings are offered in many colors including the popular black and white.

STAINLESS STEEL INLAY COMPOSITION:
316L: 0Cr14Ni9Mo2

Forever Metals stainless steel rings are popular because of their durability, their workmanship, and their unique look. If you’re interested in a Tungsten ring without the carbide composition, then a stainless steel ring has the characteristics you might be looking for. Forever Metals has offers their stainless steel rings with 316 hypoallergenic surgical grade stainless steel. The Stainless Steel ring is not as durable as the Titanium Carbide ring nor does it have the light weight characteristics that titanium has, but instead, is meant for those who desire a low cost, unique look. Perhaps not an optimal choice as a wedding band, but serves well as a graduation or a groomsman gift. Check out some of the unique shapes and cuts.

PLATINUM 900 INLAY COMPOSITION:
90% Platinum and 10% Iridium

Platinum is a very stylish rare precious metal that is more difficult to process and is not combined with the lesser valued metals that gold does, and consequently is generally safer for those that have allergies. Platinum is not mixed with the lesser metals then that of gold, so therefore platinum is safer for those with allergies. Like gold, platinum does not corrode or tarnish. Platinum is most often combined with other alloys in order to create jewelry. The most commonly used alloys for platinum are palladium, rhodium and iridium.

White Gold, Yellow Gold and Rose Gold INLAY COMPOSITION:
18kt yellow gold - 75% gold + 12.5% silver + 12.5% copper
18kt white gold - 75% gold + 5% copper + 15% nickel + 5% zinc
18kt rose gold - 75% gold + 5% silver + 20% copper

18 karat White Gold - A hot trend because it coordinates with both silver and platinum jewelry, yet is cheaper than platinum.

18 karat Yellow gold - The most traditional of metals and for many it represents a symbol of the warmth and love. Look at the mark inside the band to see what quality the gold is - usually 14k, 18k, or 24k. While 24k is the most pure, it is also the softest and rarely used in this form in jewelry.

Note: Gold Karat refers to the purity of the gold. 24 karat gold is 100% pure, 18 karat gold is 75% pure gold. 24 karat gold is too soft for inlaying and tension setting into jewelry, so therefore Forever Metals must alloy silver, nickel, copper, and zinc into the gold to harden it to make it the perfect combination of beauty, value, and functionality. Forever Metals uses 18 karat gold exclusively which is a harder substance and hence avoids surface scratches as seen in other pure gold jewelry forms. Yellow, white and rose 18 karat gold colors are produced by controlling the different alloy portions.

STERLING SILVER INLAY COMPOSITION:
92.5% silver and 7.5% copper alloy

Pure 100% silver looks bright white and is extremely soft. To enhance its beauty and durability of an inlay, the vast majority of fine silver jewelry is made of sterling silver, which is composed of 92.5% silver and 7.5% copper alloy.

Mohs Precious Gemstone Hardness

Delivered stones may be used for customization. Gemstones may be set in just about any Forever Metals tungsten ring, however we recommend setting the smallest 1mm stones in at least 4mm width rings or greater. Most of our rings specify a round cut, 1mm, 1.5mm or 2mm in diameter. Stones must be 4mm in width or less and must be accompanied with bezels. Bezels come in all different shapes and metals such as stainless steel, gold or silver. Forever Metals uses silver bezels with synthetic cubic zirconia because these work best and have demonstrated the best quality.

Stones must have a unique hardness to be burnished into the tungsten. Forever Metals is not responsible for loss or stolen packages and customers assume all responsibilities when mailing or delivering packages. Forever Metals will set any gemstone, however we don't guarantee the gemstone from cracks and chips when burnishing your gemstone. Burnishing weak and fragile gemstones could result in a cracked stone. Make sure that your gemstone is a hard gemstone on the Mohs hardness scale and purchase high quality diamonds from reputable dealers. Most second hand dealers, even large companies, skew their certifications and classifications slightly (especially on the internet) to earn your business.

Gemstones offer a unique array of vibrant colors for a long lasting wedding ring. Their rarity, durability and hardness make them very desirable and valuable. While softer stones can be beautiful, they aren't the best choice for tungsten, titanium, or ceramic jewelry. Hard metal rings require hard gems due to their settings (burnished or tension set). The Mohs scale registers a stone's ability to resist abrasion; 10 (diamonds) being the strongest and 1 (talc) being the weakest. Anything less than a Mohs scale of 7 is not adequate for our tension and burnish setting processes. Generally speaking, the purest and most vivid color gems can be the most expensive. Forever Metals recommends limiting your selections to rubies, sapphires and diamonds.
