RAMAN INTERNATIONAL GEMS LTD.
Gemstones & Jewelry Care

Try to protect any jewelry from scratches, sharp blows, harsh chemicals, extreme temperatures and sunlight.
Store jewelry separately so it doesn't scratch other jewelry.
When doing household tasks such as gardening and cleaning, be certain to remove rings.
Put your jewelry on after washing and applying any makeup/hair spray.
Never wear jewelry while swimming in a swimming pool.
The chlorine can cause damage to various gemstones and gold.
Gemstones may become loose in their settings (and possibly fall out).
Avoid storing your jewelry next to a heating vent, window sill or on a car dashboard.
Store jewelry away from sunlight as the sun may fade the gemstones.
Always store bead necklaces (such as lapis, pearls, etc) flat as silk stretches over time.
Always carefully store any fine jewelry.

Be certain that stones mounted in rings are not loose or rattle.
If you have bead necklaces such as lapis or pearls, store them flat as silk stretches over time.
Do NOT store pearls in plastic bags!
Sterling silver will polish up by rubbing or buffing it with a soft cotton cloth or a Sunshine Cloth. If you store silver in plastic bags with an interlocking seal, it will be less prone to tarnish.

AMETHYST
Amethyst, like its cousin, Citrine, are an extremely durable stone that will withstand normal cleaning, but avoid direct heat.
AQUAMARINE
Do not use an ultra-sonic machine; avoid heat as it may cause discoloration.
BLUE TOPAZ
Care should be taken when cleaning a topaz of any color. Do not use an ultrasonic machine. Avoid prolonged exposure to light and heat, as well as sharp blows or sudden temperature changes.
CITRINE
As quartz, citrine is able to withstand normal cleaning but avoid direct heat.
EMERALD
Because emeralds are oiled and usually included to some degree, this stone should not be placed in an ultrasonic cleaner. Emeralds should be cleaned gently with a small brush and lukewarm water. Avoid sudden temperature changes and sharp blows.
GARNET
Garnet is an extremely durable stone and therefore will withstand normal cleaning.
OPAL
Opal is a soft stone that requires care when cleaning. It should not be placed in the ultrasonic cleaner, nor should you use an ammonia based cleaner on the stone. Clean with a soft cloth or occasionally a combination of a mild non-detergent soap and warm water with a soft brush.
PEARL
After each wearing, clean with a soft cloth. Periodically clean with very mild non-detergent soap (Woolite®); lay pearls on a clean towel and dry completely before wear. Never use ultrasonic or steam cleaners. Use only commercial jewelry cleaners that are made specifically for pearls. Avoid contact with perfumes, cosmetics and household cleaners, and return your strand to your jeweler for periodic professional cleaning and restringing.
PERIDOT
Do not use an ultra-sonic machine. Avoid sharp blows and sudden temperature changes.
RUBY
Rubies are fairly durable stones; however, the filling process often used on rubies requires special care when cleaning the stones. This enhancement technique may wear over time if treated harshly or exposed to strong solvents or abrasives. Avoid direct heat.
SAPPHIRE
Because the heat treating process used is permanent, sapphires are an unusually durable stone. Normal care in cleaning is used, but avoid direct heat.
TANZANITE
Clean with mild soap and water; do not use an ultrasonic machine. Avoid sudden temperature changes and sharp blows.
