I use the following materials: Stainless steel, raw brass and antique brass plating, nickel and lead-free pewter (created exclusively by and for Stella Jewelry), semiprecious stones, glass beads, fresh water pearls. Chains, rings and other component are either in stainless steel, raw brass or different plating color over brass or stainless steel. Stainless steel earring rods and hooks or other hypoallergenic alloy.
It is advised not to store your jewelry in sunny places because some stones and other parts may become discolored over time.
STAINLESS STEEL: Solid metal jewelry such as stainless steel is safe to wear in the shower, while swimming or while working out. It is a hypoallergenic metal, will not rust, tarnish or change color.
PEWTER: Pewter does not tarnish, but it can sometimes react to the pH of the skin. If it loses its shine, simply wipe with a dry, soft cloth designed for silver.
RAW BRASS: Raw brass (an alloy of pink copper and grey zinc, lead free and nickel free) oxidizes naturally in contact with air and skin. This natural patina creates over time a darker finish with a vintage look. This look is intentional; it is not a manufacturing defect.
To prevent the premature oxidation of your raw brass jewel, keep it in a small hermetic bag. Also avoid going under the water with your jewel (shower, bathing).
To clean raw brass and restore its original luster, brush it with an old toothbrush and toothpaste or a metal polish such as Brasso. Then rinse, dry well and store in an airtight bag.
It is possible that the skin of some people, due to heat, dampness and skin acidity, reacts to direct and prolonged contact with raw brass, to create a grey-green tint on the skin. This chemical phenomenon is completely normal. To remove oxidation, clean the skin with a cloth and mild soap.
ANTIQUE BRASS, COPPER OR BLACK NICKEL : Note that only raw brass oxidizes. Any other antique brass plated components do not tarnish (a brass base with bronze-brown plating), such as some chains, rings, clasps and ear hooks.
