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.
This is exciting news for all of us at Omi Gems and Omi Privé. Our Kashmiri Sapphires are among our favorite gemstones. To be able to imagine them in terms of their real age makes them even more magnificent in our eyes.
The platinum Omi Privé ring shown on the left and at the top of this post features a 3.43 carat Kashmir Sapphire accented with French-cut tapered diamond baguettes and round brilliant-cut diamonds.
About a year ago, interesting colors of purple spinel started showing up in the market. Spinel comes in a beautiful range of reds, pinks, blues and purples, but until now I haven’t seen much of the intense purple you see in the photograph at the top. This deep, rich purple is very similar to the color of alexandrite when viewed in incandescent light. Read more »
Pantone always has surprises up their sleeves when it comes to color. Each year the “Color Authority” invigorates our world by unveiling their one select color choice. But for 2016 they’ve really surprised us by announcing two colors. Welcome to the world Rose Quartz and Serenity! Leatrice Eiseman, Executive Director, Pantone Color Institute states “Joined together Rose Quartz and Serenity demonstrate an inherent balance between a warmer embracing rose tone and the cooler tranquil blue, reflecting connection and wellness as well as a soothing sense of order and peace.” The soothing, calming nature of colors in the Spring collections are led by Rose Quartz, a persuasive yet gentle tone that conveys compassion and a sense of composure. While a transcendent blue, Serenity, provides us with a naturally connected sense of space.
This “engaging combo” perfectly complements so many other colors which convey both lightness and intrigue. Here are some color pairing examples:
Rose Quartz and Serenity are represented in a variety of stones, including sapphire, pink tourmaline, aquamarine, and padparadscha sapphire. The Pantone Institute® 2016 Colors of the Year can also be represented in the metals you wear, like rose gold and platinum.
The possibilities are endless!

The concept of phenomenal jewelry goes beyond the incredible allure possessed by such high jewelry as the Wallis Simpson Bracelet or the Heart of the Ocean necklace. Phenomenal jewelry, and more specifically, phenomenal gemstones, are those rare stones nature has seen fit to bless with the extraordinary gift to create unusual optical effects: moonstones, opals, pearls, star sapphires, alexandrite. All have the uncanny ability to create a unique waltz between color and light — an interplay that translates into a seductive dance of rainbows; or a mischievous cat’s eye; or a curiosity as to the exact color of the stone.
On Tuesday, March 29, 2016, Aaron Faber Gallery, will open Phenomenal Jewelry for the gallery’s annual spring exhibition. The exhibit explores how 21 celebrated jewelry artists have embraced the unique waltz of color and light shown by phenomenal gemstones into an astonishing piece of jewelry artistry.
We are excited to present the latest Omi Privé designs including color changing alexandrite and opals during this unique event.
Tuesday March 29th – Saturday April 23rd

We are always excited to welcome the fall season at Omi Privé, as it celebrates sapphire, the birthstone of September. Sapphire is named from the Greek “Sappheiros,” which is roughly translated as “blue stone.”
Sapphire comes in a wide range of blues, varying from very light to deep blue that can appear nearly black. A slightly subdued hue of sapphire known as cornflower blue, displays a lighter and more open blue, which is preferred by many. A highly valued shade of sapphire is “Royal Blue,” which is a very deep, rich blue. The very finest sapphires are a velvet, slightly violetish medium to medium dark blue, often called Kashmir blue, after its original location in India.
A wondrous fact about sapphire, besides its durability (it is a 9 on the Mohs Hardness Scale), is that it is found in a multitude of colors. Generally referred to as “fancy sapphires,” these include pink, purple, violet, yellow, orange, green and their intermediate hues. Some sapphires do exhibit a color-change, most often transitioning from blue in daylight or fluorescent light to purple in incandescent light. Padparadscha sapphires are amongst the rarest, exhibiting a unique combination of pink and orange, reminiscent of a warm sunset.
This award-winning platinum ring features a 20.03 blue sapphire certified as “Royal Blue”.
