Sri Lankan Sapphire: Up Close & Personal

Wednesday, May 2nd, 2012

We always have beautiful things to see at Borsheims. The artwork above the front entrance is definitely on that list!

This is a microphotograph of a Sri Lankan Sapphire.

Sri Lankan SapphireThe tiny cracks appear in the natural stones and are called rutile silk. When sapphires are heat-treated, these rutile silk can disappear. That is one way that jewelers inspect a stone, by looking for the natural inclusions within it.

A lot of technical info, but it sure makes a beautiful picture when photographed at 25x magnification! This photograph was done by John Koivula, an internationally known gem microphotographer. If you’re interested in his work, check out his website. It’s fascinating to see what these gemstones look like when viewed up close!

Up Close and Personal with Moldavite Tektite

Sunday, April 24th, 2011

You know Moldavite Tektite, right?

Me neither. But get ready for a close up view of it:

This is the art adorning our main entrance at Borsheims, ready to greet Berkshire Hathaway shareholders when they arrive this week. It is a microphotograph (meaning a reallyclose close-up) of a Moldavite Tektite stone.

Looks like a mountain scene, no? One of our favorite artists, John Koivula, took this amazing microphotograph. This moldavite tektite was found in the Czech Republic and has unbroken, mountainous, glassy spires. It is believed that moldavite was formed 15 million years ago by the impact of a meteorite. Here’s what it looks like not-so-up-close.

So come on over, Berkshire Hathaway shareholders. Admire our close, personal view of Moldavite Tektite. And then come into Borsheims and see all the other amazing stones we have!

New Micro-Gem Art Welcomes Berkshire Weekenders

Wednesday, April 21st, 2010

Hello Weekenders,

Here at Borsheims, we always offer our clients the most gorgeous jewelry. Our entrance is no exception, but the art in our atrium offers a different view of amazing gems that we sell. Borsheims AtriumOur glass atrium always showcases a micro-gem picture by John Koivula. In honor of the Berkshire Hathaway Shareholder’s Weekend this year, we recently added a new print. This one (pictured left) is actually a Brazilian Topaz magnified 40x.

The photo shows epigenetic mineralization in a cleavage plane of the topaz. It was photographed in polarized light. This special photo was taken by world-renowned photographer John Koivula. John has received numerous international awards including Nikon’s Small World Competition” and Kodak’s “Professional Photographer’s Showcase.” MicroWorldofGems offers a great biography of the photographer. The following short description was taken from their site.
Born in 1949 in Spokane, Washington, USA, John Ilmarii Koivula has been studying and photographing the microworld of gemstones since 1961. As an extension of his inclusion research and microscopy he has developed several useful illumination techniques applicable to gemology. He introduced fiber optic illumination to gemology and discovered many of the micro-characteristics now routinely used in the separation of treated stones from natural gems, such as internal diffusion in proving treatment, chromophore cannibalization and the usefulness of intact carbon dioxide and other fluid inclusions in proving natural color.
When you are in town for the Berkshire Hathaway Weekend, make sure to stop by Borsheims and check out this incredible photograph along with all the rest of our beautiful jewelry.

See you soon,
