Surgical Steel (316L)
Surgical steel (316L) is an alloy of iron, chromium, nickel, and molybdenum. This alloy has been specifically tested for nickel release and complies with European standards for safe use in jewelry. Surgical steel is strong, durable, and has a bright silver color. Although the nickel content is low, some individuals with a nickel allergy may still experience mild irritation. Maintenance is simple: clean with a soft cloth and mild soap.
Composition:
• Iron
• Chromium
• Nickel
• Molybdenum
Properties:
• Color: Silver-grey
• Biocompatibility: Good (slight nickel release possible)
• Maintenance: Clean with mild soap and water
Titanium (6AL-4V-ELI / ASTM F136)
Titanium 6AL-4V-ELI (grade 23) is a premium titanium alloy made up of 90% titanium, 6% aluminum, and 4% vanadium. This alloy is completely nickel-free and highly biocompatible. Titanium is extremely lightweight, strong, and corrosion-resistant, making it ideal for new piercings and people with sensitive skin. It has a matte silver appearance. Maintenance requires just rinsing with warm water and mild soap.
Composition:
• Titanium (90%)
• Aluminum (6%)
• Vanadium (4%)
Properties:
• Color: Matte silver-grey
• Biocompatibility: Excellent
• Maintenance: Rinse with mild soap
Titanium-Niobium
Titanium-niobium is a combination of pure titanium and a small amount of niobium. The result is a fully nickel-free, hypoallergenic material ideal for people with highly sensitive skin or allergies. Titanium-niobium has a light silver color and can be anodized to achieve colorful finishes. Minimal maintenance is needed: just rinse with mild soap.
Composition:
• Titanium
• Niobium
Properties:
• Color: Light silver
• Biocompatibility: Excellent
• Maintenance: Rinse with mild soap
Nickel-Free Steel (CoCr)
CoCr (cobalt-chromium alloy) is a nickel-free alternative to traditional surgical steel. This alloy offers very high strength, excellent wear resistance, and strong corrosion resistance. Thanks to its high biocompatibility, CoCr is very suitable for piercing jewelry. It has a bright silver finish with a beautiful shine. Cleaning is best done with lukewarm water and a soft cloth.
Composition:
• Cobalt
• Chromium
Properties:
• Color: Bright silver
• Biocompatibility: Very good
• Maintenance: Clean with soft cloth
18 Karat Yellow Gold
18 karat yellow gold consists of 75% pure gold. The remaining 25% is made up of approximately:
• 60% silver
• 38% copper
• 2% zinc
This creates a warm, rich golden color. 18 karat yellow gold is strong and generally well tolerated. Gold jewelry can occasionally tarnish due to contact with skin moisture; this can easily be polished away with a soft cloth.
Composition:
• 75% Gold
• 25% Other metals (60% silver, 38% copper, 2% zinc within the 25%)
Properties:
• Color: Warm yellow gold
• Biocompatibility: Good
• Maintenance: Polish if tarnished
18 Karat White Gold
18 karat white gold consists of 75% pure gold. The remaining 25% is made up of approximately:
• 66% copper
• 19% zinc
• 15% nickel
The jewelry is finished with a rhodium plating for enhanced brightness and protection. The nickel release has been tested and complies with European standards. 18 karat white gold has a brilliant white color.
Composition:
• 75% Gold
• 25% Other metals (66% copper, 19% zinc, 15% nickel within the 25%)
• Rhodium plating
Properties:
• Color: Bright white
• Biocompatibility: Tested and safe
• Maintenance: Regular soft polishing
18 Karat Rose Gold
18 karat rose gold consists of 75% pure gold. The remaining 25% is made up of approximately:
• 94% copper
• 4% silver
• 2% zinc
Thanks to the high copper content, rose gold has its characteristic warm, reddish color. Regular polishing helps to prevent oxidation.
Composition:
• 75% Gold
• 25% Other metals (94% copper, 4% silver, 2% zinc within the 25%)
Properties:
• Color: Warm red
• Biocompatibility: Good
• Maintenance: Polish to prevent oxidation
14 Karat Yellow Gold
14 karat yellow gold contains approximately 58.5% pure gold. The remaining 41.5% is composed of various metals such as silver and copper, in varying proportions. 14 karat gold is slightly less warm in color than 18 karat and is highly durable, making it ideal for everyday wear.
Composition:
• 58.5% Gold
• 41.5% Other metals (exact composition varies)
Properties:
• Color: Lighter yellow gold
• Biocompatibility: Good
• Maintenance: Regular polishing
925 Silver
925 silver, also known as sterling silver, consists of 92.5% pure silver and 7.5% copper. This composition offers a good balance between beauty and durability. Silver can oxidize and darken when exposed to air and moisture, but this can easily be polished away with a silver polishing cloth.
Composition:
• 92.5% Silver
• 7.5% Copper
Properties:
• Color: Bright silver
• Biocompatibility: Good
• Maintenance: Polish to remove oxidation
