The Dragon and the Alexandrite:

 

An extraordinary piece of jewelry deserves attention from gemstone connoisseurs and jewelry lovers.

 

The above shown ring was crafted out of platinum and weights nearly 50 grams. The eyes of the dragon are made from custom cut red Burmese spinels of best quality. The center stone is a stunning Ceylon Alexandrite, also custom hunted and re-cut from 2.5 carat gem.

 

In daylight, this Alexandrite displays deep rich ivy green and then surprises with a dramatic change to berry red in tungsten light. Intense luster and greatest clarity make this gem a rare dainty.

 

It work was commissioned from Asia. The hunt for the Alexandrite, the design and production took over six months to conclude.

Why are many gem mining countries so poor; and do not profit much from their natural wealth?

Because their governments choke off local business by regulations that were intended to support the local trade. The main value of gemstone is not in mining itself but in the work that lies behind it. Namely cutting, setting and marketing of gems and jewelry. Strangely though, this part of the value chain is always located in countries that have no natural gemstones, like Thailand, Hong Kong or Germany. Why?

We have seen this in many countries, but here is an example from Sri Lanka:

To obtain a license for the legal export of gems from Sri Lanka one needs first to cut through much red tape. Compared to the red tape we may bemoan in the west this red bared wire. (Many miners do not even have an ID)

If you have a license (and a costumer to ship to) you will spend at least one day in the "Gem Authority" where your export is examined, registered, certified, valued, packed, and finally is sealed with 6 wax seals and six (no kidding) different signatures on twelve documents with double copies. If something went wrong in this paper orgy or somebody didn't show up to work you will have to come back next day and next.

Finally, when all is done, the package goes into the Gem Authorities safe and stays there until DHL, and only DHL, comes once a week; and charges you double than Fedex or 50 times more than normal airmail. (There is rumor that the boss of the gem authority is a close friend of the boss of DHL but who knows?)

Hence all shipments from Colombo are made in big parcels, preferably pre-shaped, to Bangkok or HongKong, where they are split up, cut, set in jewelry and or marketed as gemstones. Bang, like that, 75% value creation has left the country. The miners are left with digging in the dirt. A few whole sale traders do OK but thats it. 

Thus, Sri Lanka shots itself straight out of the moste valuable part of gem business.

Why does the government do this? No bad intention. Actually they intended exactly the opposite. They wanted to control rough from leaving the country to be cut elsewhere. But, as governments tend to do, they got it wrong; and far too late.

USA cracks down on Irradiated Gems

 

The US government has finally started to worry about irradiated gemstones.

 

For starters, the Nuclear Regulatory Commission (NCR) has targeted the $1+ billion sales of "London" blue topaz into the USA.

 

Though the laws regarding irradiated gemstones are as old as 1986, the trade has so far mostly ignored the testing requirements. Blue topaz with excessive radiation levels can be found in any corner jeweler.

 

But the winds have changed: In a meeting on the 26th of July, the NCR stressed a renewed determination to protect consumers from radioactive jewelry.

 

As a result, retailers are already pulling blue topaz off their shelves. Further enforcements are scheduled. It is expected that diamonds, cat's eyes, beryl, tourmaline and kunzite are going to be included as well.

 

The NCR states clearly that any unlicensed sale of irradiated gemstones in the USA is illegal. Read the original NRC document here 

 

We think: Right so. Well done!

Confused Blues

 

After the market for yellow, orange and padparadscha sapphire has been thrown in turmoil and devalued by the so called "beryllium surface diffusion", the same is now happening with blue sapphires.

 

To the dismay of many traders and miners, this year has shown a new beryllium treated on blue sapphires. This, now second generation, beryllium treatment is not confined to the surface but penetrates deep into the gem.

 

It seems inevitable that the market for heated blue sapphires is going to plunge even further. Some talk about a collapse because the deep-surface treatment will hit a market that has already been fighting with falling prices for years. 

 

Beryllium treated sapphires are now being offered for as little as $10/carat in the wholesale market. With identical looking heated sapphire trading for $500+/carat one can imagine the confusion and mistrust amongst buyers.

 

As a side-effect, the prices of colorless sapphires (which are best suited for the new treatment) have been skyrocketing as well. This would explain why white sapphires have been so hard to obtain in 2007. 

 

The producers of heat treated sapphires seem to have the choice only between either starting beryllium treatment themselves or managing with even lower prices. While the latter might ruin smaller and midsize suppliers, the former will only lead to further price reductions, and the problem is only postponed.

 

Thoughts on the business implication of gem treatment can be found on this discussion forum or here.

"Incomplete Gems of Life!"

 

Don Ames in California has finished and sold, for an undisclosed sum, his first work of art based on gemstones.

 

Congratulations Don! Great project.

 

The "mirror" contains over 1000 carat of rough tourmaline, sapphire, ruby, aquamarine, topaz, spinel and other gems, as well as gold (river of live) and faceted diamonds.

a)
Most importantly, heating sapphires increases their brittleness. This leads to surface weakness and chances are higher that a stone will be damaged during transport or setting. This is a widely confirmed experience not only of gemologists and gem buyers, but also of heaters.

b)
In addition, treated stones are mostly handled in parcels and not in single boxes. Since sapphire can scratch sapphire they tend to get damaged while being carried around unprotected in plastic bags.

 

To make things worse the two factors, brittleness and handling in parcels, obviously reinforce one another.

Tucson: From material to gemstones

 

Semi-precious is dead - long live semi-precious.

 

This year, Tucson has shown what all connoisseurs know: There are no "semi-precious" gemstones! A gemstone is per definition precious. If it is not, it is no gemstone.

 

The true measure is called "price per carat". Somewhere below fifty, ten or five dollar per carat, depending on where you stand, comes the transition from "gemstone" to "material".

 

Topaz, tourmaline, garnets, kornerupine and spinels finally get the attention, numbers and calls they deserve. Who will doubt that a fine color change garnet has more to offer than a treated and calibrated blue sapphire? While the former will draw crowds, the latter is sold as commodity, unseen in big parcels. If this trend continues, Tucson 2025 might be free of "material".

 

Hence we welcome and applaud the increasing diversity in the gemstone market. Over are the times when the jewelry buying public raised eyebrows and asked: "I thought sapphire is blue?" Over are the times when only hard-core-gem-junkies knew that chrome diopside is not a car cleaner.

 

With the big old three falling victim to treatments, the rise of other varieties sheds light in the tunnel.

 

And behold, educated consumers with choices are powerful consumers! Those in pursue of the quick buck in sapphire treatment will soon have tears in their eyes. Prices of what they contemptuously called semi-precious will easily outrun their "material", but by then Tucson will be for gemstones only.
