While in WWII my father sent home a necklace. On the box it says "Handmade black pearl necklace, purchased while in Italy." And 'black with orange beads between pearls shapes. It seems to me more than Shell, but the black throw me out. The beads may be true, but to be sure that you really need to get a professional appraisal is an expert gemologist or estate jewelry.
Another way to know whether they are genuine is to rub a pearl against your teeth. If is smooth, not true. Pearls will always have a roughness that can not be observed visually. The spheres could be orange coral. If they really are black pearls, their value depends on the size, quality and color. Something only someone with a "hands-on examination could be determined.
I'm going to sell an old string of pearls and a potential buyer asked to know how the pearls were "signed". In general, old objects and some new, signed simply means a means of identifying the manufacturer or designer. The antique glass, for example, a brand signature can be pressed or cut into the glass. Some vintage jewelry is "signed" with a sign makers and which raises the value if the producer is among the most popular of the moment.
For pearls, a "sign" is difficult. The only place for a signature or mark-makers are generally on the area closure. This will be the closure or "language" that enters the body's largest clip. Closures can be changed when pearls are restrung and a signed buckle can always be suspicions regarding the true creator of the pearls. If these are genuine or cultured pearls, the value is more likely in pearls in the "signature".
If these are costume pearls, the value is partly in the signature and then in the condition of the filament. The condition of the pearls is more imprtant that the condition of the cable used for stringing.Stringing can and should be done regularly for pearls worn often.
I did not see the pearls "signed" very often and like I said, that may be suspicious about their accuracy. If you sign some parts clip to see if the names or "brands" are printed there. This will only sign you.
This could be the potential buyer is looking for a specific brand of pearl costume or then again might ask, not knowing what the buyer is asking! The best thing is for the buyer to examine the pearls and to offer a price. If not happy with the price, just refuse. Some buyers are in business to sell items and bid prices only way below market value.
It 'can get the thread of a qualified jeweler for appraisal. If the pearls are costume, the jeweler should be able to tell immediately and advise against a full evaluation. If they are real pearls, the jeweler can evaluate the chapter on the basis of pearls, not the old value. This is at least a starting point.
I can not see your brooch with pearls, but the pearls take radiate in some floral, perhaps on individual "stems" or as part of "flowers". If this is the case, you have more space between the beads that make cleaning easier. If the beads are tightly packed, covering much of the gold, cleaning will be more tedious and difficult.
I will particularly clean in a moment: First, consider the care and cleaning of pearls in general. In short, the cleaning of the pin you will come down to baking soda, a good jewelry polishing cloth and mild detergent. You can opt for a jeweler to do the cleaning. I will specifically later.
"Pearls". Composition of a pearl and because care must be exercised in the wash and wear. Pearls form naturally in both freshwater and marine molluscs. The best known pearls are saltwater pearls formed into various forms of oysters. While "oriental" or totally natural pearls were the gems in ages past, pearl farming has led to a supply of cultured pearls, which would be impossible to free-ranging efforts and oysters for pearls.
unique opportunity will bring a free swimming oyster to produce an environment of pearls and only luck will lead to a natural pearl being well formed, smooth surfaced and beautiful. In pearl farms, many conditions are controlled to ensure a good crop but today pollution in the waters are damaging the growth and the provision of end pearls.
The shapes of pearls around some kind of foreign object inside the oyster shell. In cultured pearls, the object is a drop of pearl (pearl shell), contained in the oyster by pearl farmers. Seeing the object as an irritation, the oyster covers the object with layer and layer of a material called nacre. This is essentially the same material, making the finish bright and shiny shell.
Pearl nacre is made of aragonite, a type of calcium carbonate. A sort of "pearl glue" holds together microscopic plates of aragonite. Until the oyster is healthy, the nacre forms and becomes thicker in the center, developing the luster and brilliance to recognize as a pearl.
Why all this information? There is a reason: aragonite or calcium carbonate. This is the substance of the pearl, the nacre. This material is soft compared to earth formed buds. This material is easily damaged by acids, certain chemicals and abrasives. The methods used for general cleaning gems minerals can not be safely used to clean the tarnished metal and pearls at the same time. Where a simple gold item may be placed in an acid solution to remove tarnish and buffed to restore shine, that same mild acid will etch the pearl and can actually dissolve.
"What to avoid when cleaning pearl jewelry?" Important as how to clean jewelry is knowing what "NOT" to be used as a detergent. jewelry commercial cleaning liquids are too strong for pearls. Most of these cleaners contain ammonia and ammonia can damage the pearl, gloss reduction. jewelry cleaners are ineffective in removing tarnish and are designed to release and remove dirt and grime than remove tarnish.
Avoid any cleaner with ammonia, chlorine or abrasives added. Avoid jewelry or silver polishing cloths with a layer of red lipstick. The lipstick is a polishing compound but the red material (iron oxide) can easily get lodged in unseen recesses of a pearl and pearl make unpleasant.
"What used to clean and remove tarnish metal beads?" Oh my, now we get into basic elbow grease! A house cleaning safest form is done by taking a wet paste of baking soda and gently rubbing the metal. If fogging is not severe, moist soda a mild abrasive will remove it. Rub with your fingers on the metal only, with a soft brush or implement such as a wet toothpick or cotton ear swab for hard to reach areas. To restore shine to the metal, the follow-up with a fine quality jewelry polishing cloth metal.
I suggest one of the chemically treated cloths, such as "Sunshine Cloth" on one hand and jewelry tool supplier. Other similar cloths are available at jewelry stores. Frankly, many employees do not know much about jewelry supplies cleaning offering. So be sure not to get the kind with a layer of red lipstick, though recommended. craft shops and jewelry stores RioGrande often used as a source and should be able to get a "Sunshine Cloth" for you. Like other similar fabrics, light action quickly removes tarnish. With a light mist, you can use the cloth alone and skip the baking soda. These fabrics are used "as is" and are simply discarded when used.
To follow up this quick rinse cleaning with a mild detergent in a dish is a good idea. This will remove any residue. Just take a solution of dish detergent like Joy (remember, no ammonia!), Rub gently with your fingers, rinse in warm water and dry. That is all.
"The security of pearls." While cleaning the pin, gently grasp each pearl and see if it turns the shaft assembly or within the setting. If on a metal stem, the pearl should be removed and re-cemented with a clear two-part epoxy cement. This is probably a job for the jeweler to do. If dissolved in a claw or type setting pole, a jeweler can quickly and gently tighten the settings.
"Cleaning by a jewelry store." You may decide to let a jeweler clean the pin and secure any loose beads. If the beads are removed and re-cemented, while the pearls are removed the brooch may be machine polished to a nearly new condition without fear of damaging the pearls. If cleaned with the pearls intact, the jeweler will use fine rotary brushes to polish away the tarnish. Then, everything is cleaned in a mild detergent solution generally using an ultrasonic cleaner.
Before doing any of the things that I just suggeted to you, you should go see a jeweler and ask him some questions that I just mentioned. In this way we get all of your base covered and not tarnish the pearls.
