Materials + Methods

Costume Jewelry: Aluminum + Surgical Stainless Steel
  • BOND Hardware does not use nickel, copper, or brass — unlike most costume jewelry.
  • This means BOND Hardware pieces do not turn your skin green with oxidation residue.
  • BOND Hardware pieces are also rust + tarnish free.
  • BOND Hardware does not use plated metals. Pieces maintain their original color forever.
  • Aluminum:
  • BOND Hardware uses super-light Aluminum 6061 which is 1/3rd the weight of Argentium Silver.
  • Aluminum 6061 is hypoallergenic — making it 100% safe + perfect for people with allergies + sensitivity to base metals like nickel, copper, and brass.
  • Aluminum 6061 is rust + tarnish free.
  • Surgical Stainless Steel earring posts are used on Aluminum pieces for all skin piercing elements.
  • BOND Hardware’s Aluminum 6061 is made mostly from recycled material.
  • This makes it good for the environment + lowers production expenses.
  • Surgical Stainless Steel:
  • BOND Hardware uses Medical Grade Metals, safe for people with allergies + sensitivities to base metals like nickel, copper, and brass.
  • Specifically: Surgical Stainless Steel Type 316L, which is nickel-free + contains 2-3% molybdenum for even more corrosion resistance.
  • Bond Hardware’s Surgical Stainless Steel pieces are corrosion-resistant + unplated.
  • Because of that pieces will not fade or chip over time.
  • BOND Hardware Surgical Stainless Steel pieces are rust, oxidation, + tarnish free.
Fine jewelry: Argentium Silver is Firestain Free, Responsible Silver
  • Argentium Silver:
  • Argentium Silver is completely nickel free — making it 100% hypoallergenic + safe for your skin, leaving no discoloration (even if you have sensitive skin or can typically only wear gold).
  • Argentium Silver does not need the firestain process required by traditional sterling silver.
  • Firestains are black burn marks left by the torch-heating + soldering of traditional sterling silver, which are treated by “pickling”, the harsh chemical compound needed to remove oxidation marks from traditional sterling silver.
  • No plating is required.
  • Little to no polishing is needed.
  • Responsible Silver:
  • Argentium Silver does not firestain, eliminating the toxic chemical firestain removal process from our production process.
  • BOND metals do not contain toxic chemicals that can be transferred from the metal into your skin.
  • And no toxic waste is dumped into the environment.
  • This makes Argentium Silver safer than traditional sterling silver.
  • Safer for your body + the environment.
  • Argentium Silver guarantees the traceability of its raw silver.
  • Argentium Silver is produced using only recycled silver.
3D Printing
  • Jewelry is designed in Brooklyn, prototypes are printed in Long Island City.
  • Plastics + metals are printed by machine, then polished by hand.
  • 3D Printing allows for more efficient prototyping- less material used, less waste created.
  • A more environmentally friendly process than other prototyping techniques.
5 Axis CNC Water Jet Cutting
  • Water Jet Cutting does not use extreme heat,saving energy.
  • Eliminating extreme heat also means there is no change to materials’ chemical structure.
  • Water Jet Cutting produces a smoother, more sophisticated finish to freshly cut metals.
  • Water Jet Cutting saves on raw materials, lowering production costs.
  • Because Water Jet Cutting is free of extreme heat and hazardous gases, it is an environmentally friendly process.
Manual Finishing Techniques
  • BOND Hardware only uses stones that are hand-cut.
  • All stones + diamonds are hand-set into metals.
  • All pieces are polished + finished by hand.
  • All earring posts are soldered by hand.
  • All labor + finishing is done by hand in new york city.
Cast + Mold
  • BOND Hardware uses traditional handmade silicone mold methods. All molds are made in nyc.
  • BOND Hardware uses the traditional “lost-wax” casting method.
  • Lost-wax casting is the process of casting metal sculptures using a mold made from an original wax model.
  • Pieces are finished by hand.
  • All labor + finishing done by hand in nyc.
