Synthetic Gemstones

Posted in Gemstones, Synthetic Gemstones at 10:56 am by diamonddude1

Every now and then someone asks about synthetic gemstones and wonders if they are real or fake.

Synthetic gemstones are real gemstones that are created in a laboratory. There are synthetic rubies, emeralds, sapphires, alexandrites, and several others. All are real just man-made. As such these are produces in a relatively short time and in indefinite amounts that the value is much lower than the limited amounts of the rare natural gemstones that are found in the earth.

You should not be confused with stimulant gemstones that are mostly colored glass or other materials that may look like a ruby, sapphire, emerald or one of the real gemstones.

Intricate Custom Ring Designs Possible

Custom Design

Custom Design

Carolyn had wanted a very personal, uniquely designed diamond ring made, one that was intricate and delicate. She had not yet found anyone that could do it when she walked into our store.

The modern usage of the computer and accompanying equipment makes possible producing very intricate and fragile mountings. Almost anything is possible.

With a picture, sketch or idea a computer rendering can be made of the jewelry piece. With the customers approval a wax model of the jewelry piece can be made and viewed in a 3-D form in its actual size. If the customer accepts the wax model, it is cast, stones are set and the ring is polished. Done!

Carolyn’s anniversary band commemorated her wedding date July 7, 2007.

How To Clean Silver Jewelry

Posted in Maintenance and Repairs, Metals at 10:25 am by diamonddude1

Linda came in asking how does she clean her silver jewelry to take off the tarnish.

The jewelry she had were some chains and rings and they were turning black. This was a result of silver oxidizing or commonly known as tarnish.

To get the tarnish off you can just purchase silver cleaner from the drugstore. Longs has several brands available. Some of them are just cleaners and will just remove the black tarnish. It is usually in liquid form. These will not make the silver shiny.

Others are polishers that will remove the tarnish and polish the silver. These are usually in paste or semi-liquid form. These may not remover the tarnish in the recessed areas but will make the silver shiny.

To get  a brand new just bought look it is best to take it to a professional jeweler who will take out all the dents and scratches, remove the tarnish and polish the jewelry to a high shine.

The Yellow Tinge in White Gold

Posted in Maintenance and Repairs, Metals, Mountings at 10:29 am by diamonddude1

Joan had asked if we could check and clean her diamond ring even though she did not buy it from us. We told her it was not a problem. She also asked why her white gold ring was turning yellow and what can she do about it.

Upon inspection we found that it was an 18k white gold ring that was originally plated with Rhodium.

We explained to her that gold is yellow and pure gold is 24k. Eighteen karat gold is eighteen parts out of twenty four which make the gold content 75% the rest is white metals primarily nickel, palladium and zinc. That would mean that the majority of the metal is yellow. The whiter metals will dilute the yellow color a bit but still leave it with a tinge of yellow.

Joan’s ring was rhodium plated which covered the white gold and made it look whiter. Rhodium is a metal in the platinum family and is white in color, but as plating it is just a surface covering and is eventually is worn off exposing the yellowish tinge of the white gold.

We told her that she can have it periodically re-plated, the frequency dependent on how active she is, possibly every year or two.  She could also have it remade in platinum or palladium, other white metals, never having to worry about color changing or plating.

She decided to have it re-plated and to make it in platinum or palladium when she was ready to change the style of the ring, maybe in a year or two.

Thank Goodness for Ring Guards

Posted in Maintenance and Repairs, Mountings at 10:31 am by diamonddude1

Agnes came into our store to have her diamond ring cut off her finger. It was not that it was tight but she had developed arthritis and her knuckle became larger where the ring would not come off. She was concerned that after we re-sized her ring to go over her knuckle it will be too loose and spin a lot.

We suggested several alternatives. Fortunately the size difference between her knuckle and the inside of her finger was not a great deal of difference, just about a 3/4 size difference. For her we suggested using a ring guard. It is a clip-like piece of metal that acts as a spring inside the ring and will take up the looseness once it passes the knuckle.

In extreme cases we recommend a special hinged band that opens up to go past the knuckle and locks to the proper size with no looseness.

Ring guards make for a more comfortable fit and works very well for the people that really need it. Agnes was happy that there was a solution for her problem because she still enjoys wearing her diamond ring.

Yes, Gold Does Tarnish

Posted in Maintenance and Repairs, Metals at 10:33 am by diamonddude1

John came in yesterday and brought in a couple of Hawaiian Jewelry bracelets. They both appeared darker, one noticeably more than the other. He questioned if this was real gold because it is the first time he has seen this happen. He has other 14k yellow gold jewelry but it did not look as dark as these bracelets.

We told him that it was not a problem he should worry about. We explained that 14k gold jewelry will get darker if it sits and is not worn.

He bought these bracelets several years ago to give his granddaughters when they turn sixteen. They are only nine and seven. These bracelets were in storage.

When jewelry is worn it does not have a chance to tarnish because it constantly is in contact with clothes and other objects.

The alloys in the gold, primarily the copper in the alloy will tarnish and make the gold appear darker. It is a surface color change and can easily be removed by polishing it. His bracelets were polished, restoring it to its normal color and given back to him. All’s well again.

Diamonds Can Chip

Posted in Diamond Detection, Maintenance and Repairs at 10:35 am by diamonddude1

Helen called today to ask if diamonds can chip. She was under the impression that diamonds were the hardest substance so how can it chip.

We told her that a diamond is indeed the hardest substance in the world. Meaning that as the hardest it can scratch any other substance, unfortunately it is not the toughest. It can chip. It is sometimes chipped when the diamond is being set in a mounting. Other times it is chipped when it is worn.

Due to its hardness a diamond is fairly durable. If you took care of your diamond it can have the same beautiful look for generations.

Valuing Tahitian Pearls

Posted in Gemstones, Pearls at 10:37 am by diamonddude1

tahiatianYesterday June came into our store to ask us if the strand of Tahitian pearls she bought was a good value. She did not bring it with her but proceeded to describe it as 9 to 11 mm and 17″ long.

We told her that with pearls we would have to see it to determine the quality and in turn that will determine its value.

Tahitian Pearl value is determined by the size, shape, roundness, smoothness, luster and the thickness of the nacre. Color will vary from silver to jet black but color does not affect its value as much.

Cultured Tahitian pearls are usually left in the oyster for three years. Within these three years the nacre is built up to 4 mm. Because of the length of time it allows for deformations and blemishes to form. If a smooth, round, lusterous pearl is found in the oyster it will have a very high value.

There are pearls that are taken out of the oyster sooner than three years. They are  left in the oyster only 6 months to a year and then removed. These will not have a very thick nacre, and the luster is usually not as good. Since the seed for the pearl is not left in it very long the pearl will not have many blemishes or deformations. It may look like a high quality pearl because of the lack of blemishes and is round but its value will not be high. They are sometimes referred to as “young pearls”.

For June we cannot determine whether she got a good price or not until we have a chance to physically inspect her necklace.

Japanese Family Crest

Posted in Uncategorized at 10:39 am by diamonddude1

mon

Donna called yesterday asking if we could help her research and find her mon (Japanese Family Crest), so that she can make a gold pendant for her family.

The short answer is no we cannot research it for her.

The long answer is that reaseach has to be done within the family. She is to ask all her older relatives if they know what the design is. Some have kept a kimono that may have the mon printed on it. Gravestones in Hawaii may sometime have it engraved. In Japan if you know where your family cemetery is more than likely it is on the headstone.

The Japanese family crest is a passed-on heritage. Fathers pass theirs to their sons. Mothers have a personal women’s mon that would be passed on to the daughters.

Unfortunately it does not necessarily go by last names although there are books that would have it listed as such. The women’s one is just passed from mother to daughter and is not associated with any last name. Any last name is connected to a male side of the family.

As the older generation passes the family crest may be lost. If there is interest in preserving this heritage you should find it now before it is too late.

We wish you luck in your reasearch.

HAVE YOUR RING INSPECTED

Posted in Maintenance and Repairs, Metals, Mountings at 10:41 am by diamonddude1

head with arrow

Michele came in today to resize her diamond ring. As standard take-in procedure we started to document the details of the ring on a receipt. A plotting was made for diamond for identification. Its size was recorded. The side diamonds were also counted and listed on the receipt.

Upon further inspection with a magnifier we noticed that the base of the prongs that was holding the one carat diamond had a crack running all around it. It was not visible to the naked eye. If this was left as it was it would have been just a matter of time before the prongs broke off and diamond would have been lost.

It is essential to have your ring professionally inspected periodically to prevent these types of disastrous consequences.

Hawaiian Jewelry Enamel

Posted in Hawaiian Jewelry at 10:42 am by diamonddude1

Cindy wrote: “I have had to re-enamel my Hawaiian bracelet three times in two years with another company. Did they just do a poor job of enameling or is there something I can do that will make it stay longer?”

Hi Cindy,

There may be several reasons why the enamel did not stay in very long.

If your bracelet is very thin and flexes a lot then the enamel will not stay in it very long. There is not much you can do except be more conscious of not bending the bracelet.

If the bracelet is thick enough and does not bend readily then it may be the letters are not cut deep enough to hold the enamel very well. The letters should then be recut to solve the problem.

There are also two types of enamel that is in current use. One is epoxy resin which is easier to apply, is not as hard, does not adhere as well and will not last as long as glass enamel. Epoxy is used more commonly. Glass enamel is a more lengthy process of melting glass powder into the cut letters. It must be applied in layers before the whole letter is filled. It will last longer than the epoxy.

The length of time the enamel stays in a bracelet will vary depending on the activity of the wearer and the flexibility of the bracelet.

Epoxy enamel cost less to apply about and will cost about $2-$5 a letter depending on who does it. Glass enamel is a labor intensive method and will cost between $5 -$10 a letter.

I hope this helps to answer your question.

Jewelry Store Employee Steals $12 Million In Gold

Posted in News at 10:46 am by sweetmomentsbythediamondspecialists

Hi All!
I thought you might find this article interesting. Jeanne, Sweet Moments

Queens, New York:
Teresa Tambunting pilfered $12 million in fine gold jewelry and bullion over the past six years from her employer, Jacmel Jewelry.

The fifty year old vault manager cut a slit in the lining of her purse and took the pieces out one by one over the six years.  The day by day pilfering resulted in her stealing over 500 pounds of gold.

Teresa confessed to her crime, when in January 2009, the company underwent an audit and found that their inventory came up $12 million short.  In February, she returned 80 pounds of the stolen property. The other 450 pounds were found stashed at her home.

Why would someone with an annual salary of $165,000 do such a crime? Teresa’s attorney is planning to use obsessive compulsive disorder as her defense.

If convicted Tambunting faces up to 25 years in prison.

Should You Insure Your Jewelry?

Posted in Uncategorized at 10:48 am by diamonddude1

We occasionally have our customers ask about jewelry insurance. Some are devastated when they have lost their diamond ring and find out that it was not covered by their homeowners policy.

Insuring your jewelry is a personal choice and not everyone will feel it is necessary. Some have paid for insurance for years and never lost anything and then felt it was a waste. Others had insurance when it was lost and were able to get a replacement. They were extremely happy that they had it.

We had written an article in Time Warner Oceanic Around Hawaii website that explains the process of getting insurance, what it covers and alternatives if you choose not to get insurance.

Concerns About Jewelry Left for Repair

Posted in Maintenance and Repairs at 10:49 am by diamonddude1

About once a week we get questions about jewelry left in a store for repair. People have great concerns about getting back the same diamond that they have had for many years.

It is a very legitimate concern. Everyone would like to be sure that they keep what they always have had, but when it is left in a store they do not know how they can get those assurances. They have heard enough horror stories to be very cautious about their jewelry. For many people years have passed without having their jewelry repaired for fear that it may be lost.

We have published an article on the Time Warner Oceanic Cable Around Hawaii website which details the process and procedures to ensure that you get back what you leave for repair. Follow this link for the details.

We hope that for those that have a need to repair their precious jewelry, we have helped disperse some of the fear and allow you to be able to enjoy wearing your jewelry again.
