Beryl Beryl Good Company

Family Ties Make This Gemstone Rock

Keep Track--Take Notes
The species is the mineral family with which a gemstone is associated . But depending on that species, you may find a few or many varieties of that species. With gemstones, the inclusion of trace elements of other chemicals will be the reason it changes color. 

Looky Here
These scrumptious 3 segment dangle earrings are actually all members of the beryl family. The chemical makeup is something (or exactly) like this--- beryllium aluminium cyclosilicate

Trio of Lovelies
The Mark Patterson earrings showcase what a little 'intrusion' can do. The various beryls in these danglers are aquamarine, morganite, and green beryl top to bottom. Green beryl is not to be confused with emerald which is also a beryl stone. It's particular chemical make up will separate the two, besides their exact green coloring.

But Wait There's More
Other lovelies in this species include heliodor, golden beryl, bixbite and the lesser known goshenite. Seems like beauty runs in this family.

Light, Dispersion & Color

Ethiopian Opal--- the new kid on the rainbow block

Been Around a While
Opals of all kinds have graced the earth for millennia. That's because these rainbow hued treasures were the result of ancient earth forming activity and  a bi-product of sedimentary or volcanic occurrences. Traditionally, most opal has been discovered in Australia, where the geological climate lends itself to its creation. Ancient sea creatures like spooky-magnificent plesiosaurs whose fossilized bones found in that region have also yielded opalized bone from time to time.

Mexico was the other arid region whose climate was ideal for the production of opal, including the non-play of color variety Fire Opal.

New Discovery--Old Material
But a couple of years ago. gem shows around the world began offering volcanic Ethiopian opal, and collectors have taken a shine to the colorful gems.

Opal is ofen found in host material looking something like this example above.The uptick in sales of the Ethiopian variety was tempered by caution due to their fragility. But in actuality, all opal, irrespective of origin should be handled with care. 

Watery Stones?
Did you know opal crystals contain a significant amount of hydration? This 'watery' composition can be up to 21% in some cases. The range starts at 3% and goes up. So opals of any kind should be stored carefully and not be exposed to excessively dry environments.

Ethiopian opals in particular are often found as nodules (see above); the result of volcanic activity. No wonder local tribal groups in Ethiopia caught a colorful glimpse of them on the ground and carved them into tools, as early as 4,000 years ago. Beautiful and functional! We like that.

It's All About the Pink

Girly Diamonds Are Pink & Powerful

Perfect Pairing
The ever opulent Ms Sophia Vergara knows what is enough and not a bit more. She looked lovely in every sense at a recent event. Her very detailed dress found its perfect foil in a diamond domed ring by Harry Kotlar. Vergara was attending the LA premiere of Hot Pursuit at TCL Chinese Theatre IMAX in Hollywood. When you've got a pink diamond on, well, that's certainly enough now isn't it?

What's That in the Middle?
The hero of this ring is a stunner of an oval pink diamond. The accent diamonds surrounding the yummy pinkie are marquise shaped diamonds that form a modern floral motif. That's the way I like my flowers. Let's go in for a closer look.

Natural Beauties
Fancy pink diamonds are a natural occurrence, and as such, they come in as many shades of pink as you can shake a ring at. This feminine pink tint must have inspired the designer to create a floral design around the central stone, as that has a lady-like vibe as well.

Pretty & Pretty Rare
Here's an interesting bit to consider. Nearly all of the fancy natural pinkies come from the Argyle Mines in NSW Australia. Why is that? The jury ponders. But in general, all diamonds and gemstones are at the mercy of geology; and some terrain is more conducive to certain stones than others. 

Pink diamonds are popular today, but that does not mean they are plentiful. After all, nature calls the shots when it comes to producing these girly stones.
