• The following is to illustrate certain artifacts with opals and to provide some general and technical information about them. There are more varieties than you typically see in most retailers, and there are a lot of synthetics out there. There are also a lot of doublets and triplets on the market.

    While either a synthetic, triplet or doublet might be attractive and affordable to many, they are not naturally. What’s worse is that most people don’t know the difference, and some entities will sell certain items without disclosing and explaining what these things mean. That’s the bad part. The other bad news is, if you want something natural, and good, anymore you’re going to pay for it if it’s of quality and pending the size and specifics.

    Natural opals anymore have become quite expensive pending on the exact type. Yes, there is more than one type of opal. Pending what kind of opal it is, and it’s particulars, you will pay more or less for it. They were quite popular during the 1980’s as they have a myriad of colors which fit into the outrageous trends of the time. So suddenly they became popular, and they were relatively more affordable than they are now. The demand increased, the mines in Australia are simply not producing as much material. The strength in the Aussie dollar against the US dollar forced a doubling in the prices alone, so something had to give. That something was the quality and the rise of synthetics with the exception of certain higher end jewelers.

    I’ve always been a fan of the more unusual stones, and things you don’t ordinarily see. The illustration below is a natural opal showing no evidence of enhancements that was purchased from AJS Gems. This is a 0.97 carat trillion cabochon magnified 45x.

  • The following is a brief and exploratory study of a 3.87 carat yellow tourmaline I purchased from www.ajsgems.com Gems some time ago. The methodologies involved are non destructive and include microscopic testing as well as some imagery coupled with long wave UV testing. I thought I would share at least some of the more interesting pictures I obtained, and a few artifacts that threw me for a loop-but in a good way.

    Yellow tourmaline is more or less a collectors stone, and anything particularly of gem quality of a carat or better is considered a collector size stone. The rough is often incredibly included, so there is little yield as a result. This study is meant to be a brief version of a more complete study of like kind that may or may not be published later on. These are simply the highlights and some things that are of interest.
    I made the mistake of wiping the stone with a lotion containing tissue after rinsing it, hence why I could never get a good face up shot. It’s all dirty as a result, but it is remarkably clean for a yellow tourmaline-especially of this size. The polariscope without the polars crossed shows a slight pleochroism, but under various lighting conditions I have noticed a more obvious pleochroism within the stone. I can also tell you that it is uniaxial negative with a chronoscope, which is consistent with yellow tourmaline by pretty much any account I could find.

  • Whoa…thats a peridot! :-)

    Dear Arnold, Matt, Rung, et abla..

    My mother got her peridot today. I thought maybe the flight scheduling with FedEx might have delayed things, or the weather. There were no delays. Its ironic how you in Bangkok can get a package through the same courier as a network out of Atlanta, and even though Atlanta is just a short distance, I can bet on a package from AJS Gems arriving faster than some network. So I got to give you guys recognition for shipping merchandise out in a very timely manner.

    Where do I start on this peridot? Mom was hoping it was a little darker, but I figure when its mounted in a ring, it very well may. There are certain tell tale signs of that. However, she did compare this to her beloved Arizona peridot in a ring she bought from a local jeweler. This specimen is not your typical pale colored stuff. The Arizona stuff tends to be a paler yellowish green. Its not quite as saturated as this material. I am not going to say the Arizona stuff is bad, but its less per carat as a result. A few years back when we tried to find this same material from this locality, nobody ever heard of it.

  • Due to its proximity to some of the most historic and profitable mines in the world, Bangkok has a wide-reaching reputation for being the premier gem trading capital. Bangkok is not only a gem cutting and fashion center, but it also offers a wide range of high quality gems that can be shipped quickly to customers anywhere. Plus, the government has a hand in organizing massive gem and jewelry sales for which they will even provide taxicabs to transport buyers.

    Bangkok is surrounded by mines - not only across Asia, but also in Thailand. Thailand (the country in which Bangkok is situated), is known for its sapphire mines. Myanmar, where the rare and valuable Burma rubies are mined, is located a short distance away. Burma not only produces the finest rubies, it also produces exquisite sapphires and the worlds finest jadeite jade stones. In addition, there are exquisite sapphire mines located in nearby Cambodia. Therefore, Bangkok provides a center point for gemstone trade and fashion based on its central Asian location and on the eagerness of gemologists to maintain the citys reputation for providing the highest-quality possible gemstones.

  • The following article, written by Mick Elmore, details the dangers of a boycott of Burmese gemstones. AJS Gems’ owner Arnold Silverberg was interviewed for the article, and his views were included in the piece. The article was covered by the L.A. Times, The Associated Press, NBC and many others.

    The rich red hue of Myanmars prized rubies is a reminder to many gem dealers of the military governments bloody crackdown on democracy advocates, and talk of a boycott is increasing.

    “There is a growing awareness that it is a fascist regime,” said Brian Leber, a third-generation American gem dealer in Western Springs, Ill. “Considering what this regime has done to its own people, were troubled to see that a precious stone is offering such a great source of cash for them.”

    “Trade in these stones supports human rights abuses,” New York-based Human Rights Watch said earlier this month. “The sale of these gems gives Burmas military rulers quick cash to stay in power.” (Myanmar is also known as Burma.)

    But a successful boycott of what activists call “blood rubies” will prove difficult. More than 1,500 people from more than 20 countries registered for a gems auction that opened this month despite the boycott calls. While some rubies are exported legally, many also are smuggled out of Myanmar.

    The ruby trade puts money in the juntas pocket, since it controls mining concessions, but the scale of the profit is hard to assess. Secrecy shrouds both the gem trade and the country as a whole…

  • Dear Arnold, Rung, Matt and staff,

    I got my opal today to add to my collection. Today is a fitting day for these things as this day has a significant meaning to me.

    When I first saw the picture of the opal, I could tell 2 things right away. I knew it wasnt a synthetic by looking at the patterns of colors. That was readily obvious to me. The second thing I noticed before I even looked at the origin, I knew this was an Aussie opal. Someone wonders how I could tell, but its very easy. There is a bit of a floral pattern and an oriental character there, and you dont see that with synthetics. Lab created opals have a tell tale chicken wire pattern that you can sometimes make out with the unaided eye. The picture resembles nothing of the chicken wire pattern in the colors, or a lizard skin effect. Having said that, when you see that yellow flash, there is only one place that you see that yellow flash. Usually its either Lighting Ridge or some other locality. Regardless, this is without a doubt an Australian opal

  • Although diamonds have historically been the most cherished of gemstones for engagements and weddings some women are looking for something that is non-traditional and more personal. Colored gemstones give them a wider variety than diamonds and while diamonds generally look nearly identical to the eye, colored gemstones are much more unique.

    The richness of the earth shows up in the many varied colors of precious colored gemstones. Whether you choose a rich green garnet or a bright pink tourmaline you will cherish these stones because of their beauty and the immense variety of different choices.

    Diamonds have been more popular than gemstones because they have been advertised more and people are used to seeing them. However, in the last few years colored gemstones have become more popular because information tools such as the internet have been able to bring consumers more education about them than was ever possible in the past…
