Testing Pearls

This may not be an exact science for testing your pearls, but if you cannot get them to a jeweler this is what I do; Clean a couple of the pearls with a damped cloth or q-tip, put one of the pearls between your front teeth and rub your teeth across it, if it is gritty like sand it may be a real pearl, but some of the high quality costume pearls have been coated with a pearl coating, and the only way you can tell is if the coating comes off and reveals the glass bead beneath. I usually take a loupe or magnify glass and inspect each one first to see if there is any peeling or scratching, and if they are costume there will usually be some type of flaw. A jeweler friend of mine also told me that her husband who was jeweler for many many years, said that the smaller the light on a real pearl the better the quality. This same test is used for Fresh Water Pearls. Please don't ever use any soap or harsh chemicals on your pearls, or put them into a sonic cleaner, as it can damage them, my daughter had an expensive pearl ring and was wearing it while washing dishes, it removed the lustrous finish and the pearl was dull after that. I never dip them directly into water, since this can damage or weaken the cord they are strung on, just use a soft cloth dipped into water and wipe them carefully. Perfumes and lotions can damage pearls if allowed to stay on them, it's best to put your perfume and lotions on before adding your pearls, and wipe them off before storing them....

Stampings on Gold and metal jewelry;

There are stamps on gold jewelry that sometimes are confusing, some of the European stamps are almost impossible for the average person to understand, like me. If you have jewelry with any of the numbers below and wondered what they meant this may help you in identifying it. Some costume jewelry is heavily coated with gold, most is 12k gold filled and the majority of them are stamped somewhere on the piece, but a some are not so when testing it, you have to rub it down to the base metal to test it using an ink eraser in an inconspicuous place. If someone tells you that a piece is 12k gold, more than likely it is plated, you very rarely see jewelry done in 12k solid gold...

375 = 9c/ct

538 or 585= 14K

750 = 18K also an Eagles head {French}-18K

14KP = plumb {exact} this was not used until the 1980s.

Russian stamps = 56=583= 14K

Platinum = 900 Plat-100 Irid the dogs head was used after 1912 for platinum.

1/20 14K or 12K GF = Gold filled.

RGP = rolled gold plate

HGE = heavy gold electroplate.

Silver = 925 = Sterling 92.5% silver.

800, 825, 830, 850, 900 are European or Continental stamps for silver.

EPNS = Electroplated nickel silver

Alpaca = copper, zinc, nickel, 2% silver.
