There was a time in this great land, not too long ago, when a great behemoth of a company ruled the airwaves with a constant barrage of commercials stating that “A Diamond is Forever”. One would have been considered weird or rebellious to get engaged with anything other than a diamond. Well, things have changed here in the 21st century with a renaissance of color emerging in engagement rings. Women and men are choosing gemstones for their most important and symbolic piece of jewelry that better reflect them as individuals. It is a new age, free of any pressure or traditional bonds to choose fabulous color over the monotony of the colorless.

Prior to the days of mass marketing’s influence on the population, colored gemstones were far more popular as a symbol of one’s love for another. In fact, sapphires were the gemstone of choice in early engagement rings, not only for their beauty, value and symbolism of love, but they were also believed to reveal any infidelity of the wearer. In the 18th and 19th century, colored gemstones were valued higher than diamonds, so it was more special for a bride to receive a rarer, more valuable colored gemstone than a more run-of-the-mill diamond.

Today’s brides-to-be can choose from an incredible array of gemstones and hues. There are so many reasons that a person may connect with a particular type of gemstone. It could be as simple as a favorite color. It could be the origin of the gemstone. It could be a special cosmic trait that a gemstone posesses and creates a bond with the wearer. Whatever the reason, there is a universe of options available to the newly unshackled engagement ring shopper.

There are some practical considerations that should come into the decision-making process when choosing a colored gemstone engagement ring. One of the most important factors is durability. You will wear your engagement ring for a long time, so it is imperative to select a gemstone that will stand up to the daily grind of life. Really durable gemstones include sapphires, rubies, chrysoberyl (alexandrite), topaz and spinel. Within this list, you will find every color in the rainbow to select from.  Your choices are endless and it is entirely up to the wearer as to which gemstone speaks to him or her.

 

 

Colored gemstones are returning as the symbol of love and romance as they have been throughout history.  The few decades-long blip on the radar of mass marketed colorless stones is being replaced by a new era of freedom of choice and personal expression.  We are honored and proud to be able to play a role in so many new special moments involving our beautiful colored gemstones and award-winning jewelry designs, and look forward to many more as color returns to its rightful place in the realm of romance.

How Old are Kashmiri Sapphires?

Most people understand that gemstones are from the earth, and that they have been there for a long time. But a long time is such an abstract concept. However, when Gübelin Gem Lab is able to give the age of a gemstone using radiometric dating, that abstract concept becomes very real. How long is a long time? Think in terms of millions of years, not hundreds of thousands.  Here is an excerpt from the May 12, 2016 issue of the Gübelin Newsletter #46, on determining the absolute age of Kashmiri sapphires.


Kashmiri sapphires determined to be 25 million years old

Last fall, for the first time ever, the absolute age of a high-value gemstone has been determined. Our geochemical specialist Klemens Link used radiometric dating on the in-house Laser Ablation ICPMS facility. The method and results are published in the latest issue of the Journal of Gemmology, Vol 34, Issue 8. Meanwhile, age determination is applied regularly in our lab on rubies and sapphires, supporting the distinction of African and Sri Lankan sapphires from the Burmese and Kashmiri ones.

The determination of the exact age of Kashmiri sapphires, however, was not yet undertaken, until the Gübelin Gem Lab initiated a research project jointly with Prof. C. Liu, and Dr. C. Zhang of the Institute of Geology and Geophysics, Chinese Academy of Sciences in Beijing. Zircon crystals included in samples from the Gübelin Reference Collection have now been analysed by LA-ICPMS in the Gubelin lab, and by high-resolution SIMS at the IGGCAS in Beijing. The respective uranium-lead ages are 26.8 (±3.8) million years, and 24.97 (±0.22)  million years, mutually confirming the results.
