Thank you for visiting Marei New York. Please see below for information regarding rhodium plating below.

Black Rhodium and Black Ruthenium Plating ("Black Gold")
Black rhodium and black ruthenium are surface treatments that are electroplated using a chemical bath process to coat a base metal such as gold or silver with a dark gunmetal color.

Jewelry that is plated with black rhodium or black ruthenium will have a uniquely dark and shiny reflective finish. This dark gunmetal color is also known by jewelers as "black gold", however the piece itself will be gold or silver metal underneath. 

It is important to note that black rhodium plating will wear off over time and will leave the surface of the base metal with a unique antiqued-looking gunmetal color similar to black oxidized metals. After natural wear and tear, your piece will develop its own unique vintage "worn" look. 

ALL plated finishes are NOT permanent and will wear off or fade due to natural wear, direct contact with skin, and exposure to sweat, oils, lotions, and from rubbing on surfaces. This will reveal the underlying base metal - usually silver or gold.

Black Rhodium and Black Ruthenium Lifespan
The lifespan of the rhodium plating will depend on how often the piece is worn. With normal wearing, the black rhodium and ruthenium plated jewelry will develop its own unique patina as it wears off - and will look similar to an antique blackened finish. Generally, black rhodium plating will wear quickly on jewelry that is worn daily such as rings than on a piece that is worn occasionally. Areas that are raised that come into close contact with surfaces will wear off more quickly than areas that are indented or engraved.


Plated Jewelry Must Be Worn With Extra Care
All plated surface treatments are delicate and should be worn with extra care to help preserve the integrity of the plated surface.

Plated jewelry is NOT waterproof therefore all plated jewelry should be kept dry at all times. Please keep away from ALL liquids such as water, lotions, oils, sweat, perfumes, alcohol, acetone, hand sanitizers, hair products, makeup, and chemical cleaners, etc... Exposure to liquids can weaken, damage, and may eventually even remove the plated surface treatment.

Plated jewelry is NOT scratch proof. Please keep your plated jewelry away from all abrasive surfaces and objects that may scratch, dent, or chip the plating. Take care not to rub your plated jewels on rough textiles such as leather and denim, as this may rub off or damage the plating. 



Store your jewelry safely in a soft lined jewelry box. Jewelry boxes that feature individually padded slots for rings and posts for hanging necklaces and bracelets are also ideal. Jewelry pouches are good too but take care and keep your jewelry pouch somewhere safe so that the jewelry does not get crushed.

Know when to take your jewelry off. 
Please avoid wearing jewelry while showering, cleaning, gardening, performing sports activities such as hitting the gym, lifting weights, doing yoga, swimming, rock climbing, etc... this will damage your jewelry. We highly recommend removing all your jewelry before going to sleep. 

Avoid heat. 
Avoid placing your plated jewelry near heat as this can cause discoloration and deformation. 

Avoid exposure to liquids.
Keep it clean by gently wiping with a soft and dry, non-abrasive cloth. Do not expose to water. Never use steam or ultrasonic cleaners on plated jewelry. Do not use abrasive polishing cloths or liquid jewelry cleaners on your plated jewelry as this will remove the plating.

Avoid exposure to hand sanitizers. 
Please keep your hands clean but avoid exposing your jewelry to hand sanitizers and chemical disinfectants. These liquids contain chemicals that can eat away at precious metals and plating. Chemicals used in hand sanitizers may also cause irreversible damage your gemstones - especially pearls. Take off your jewelry before applying hand sanitizers or chemical disinfectants. 

Avoid exposure to all chemicals.
Avoid exposing all jewelry to household cleaners, hand sanitizers, disinfectants and bleach. Bleach will cause discoloration and damage to the metal and gemstones. Chlorine may also damage fine precious metals. Repeated exposure to chlorine can weaken gold's structure, eventually leading to breakage. Please keep your jewelry away from pools and jacuzzis.

Slow down the effects of silver tarnishing.
All plated silver jewelry may tarnish over time due to natural oxidation of silver metals when exposed to air. To help slow down the effects of tarnishing, keep your plated silver jewels dry at all times. After each wear, simply wipe your plated silver jewelry with a soft dry cloth and store your jewelry in an airtight container such as a closed jewelry box or ziplock bag. You may also place an anti-tarnish strip into the container.

Cleaning plated jewelry.
Simply wipe clean with a soft dry, non-abrasive cloth to clean. Never steam clean or use ultrasonic cleaners on plated jewelry. Do not polish your plated jewelry as this may remove the plating. 


Proper jewelry storage is important. 
Jewelry should never be tossed into a drawer or thrown on top of a dresser as this will cause your jewelry to get scratched and damaged.  Store your jewelry safely in a soft lined jewelry box. Use jewelry boxes that feature individually padded slots for rings and posts for hanging necklaces and bracelets are also ideal. Jewelry pouches are good too but take care and keep your jewelry pouch somewhere safe so that the jewelry does not get crushed.

When traveling, it's always a good idea to bring a small travel sized jewelry box to safely store your pieces. Be sure to keep your valuables in a safe place, such as the security safe in your hotel room - and DO NOT ever leave your valuables on the dresser or side table.
