A Tale of Two Sapphires
Designing a new ring, pendant or brooch is an exciting experience, a time of anticipation and imagination. One of my favorite steps in the process is comparing and selecting gemstones. Helping a client find the perfect gemstone for a design is almost as much fun as unveiling the finished jewel.
When selecting gemstones for a design several factors should be considered - the most important of which are color, cut and size. To help us discuss each of these factors I have posted above a photo of two radiant-cut sapphires from our inventory.
When evaluating colored gemstones the obvious first consideration is the color. Gemstones come in an amazing spectrum of colors that spans all the hues of the rainbow. Even among blue sapphires there is a great variety in shades ranging from light pastels to intense royal blues and violets. The two sapphires pictured above illustrate this colorful variety. The larger sapphire is a wonderful soft velvety blue while the smaller sapphire is a more intense shade of violet. When working on a project, I will often examine 20 or more gemstones before finding the one with just the right color for the jewel.
Cut is the second factor to consider. The cut of a gemstone should complement and enhance the beauty of a jewel. The two illustrated sapphires are wonderful examples of square radiant cuts. The radiant cut weds the classic step faceting of an emerald cut with the brilliant faceting favored by diamond cutters. The result is a wonderful marriage of elegance and sparkle that goes well with Art Deco-inspired designs and the flowing, geometric forms of Modern jewels.
A ring I recently created, Sapphire Seduction, illustrates the sparkling elegance of a radiant-cut sapphire. In another design, Purple Decodence, I chose a classic emerald-cut sapphire, because the striking geometry of the purple gemstone beautifully complements the platinum setting.
Finally we consider size. First off, bigger is not always better when it comes to fine gemstones. A smaller, beautifully cut gemstone with exceptional color will almost always have a greater impact than a larger mediocre stone. What is important is that the size of the gemstone balances and complements the other elements of the jewel without overwhelming them. Keep Goldilocks in mind - "You don't want a gem that is too large or too small, you want one that is just right for the design!"
We have discussed color, cut and size which leads to the question "How do you evaluate and compare each of these factors as you search for the perfect gemstone?" The truth is there are no quick answers, no easy shortcuts. There is no simple formula that can determine what size of gemstone is best for a given design. Online photographs rarely capture the true beauty of a gem's color - they are subject to the accidents of photography and lighting. And although grading reports are helpful in sorting the clunkers from the candidates, they fall short in discriminating the finer qualities of cut.
The best approach is to bring together a collection of the finest gemstones available from various gem cutters. After examining each of the stones in my gemological lab, I then lay them out side-by-side and carefully examine and compare each stone first hand. Evaluating the gems in person, while working with my client, allows us to select the best gem for the jewel we are creating.

The Great Pumpkin - Fancy Orange Sapphire
Fine quality fancy orange sapphires are difficult to come by, especially when compared to other fancy color sapphires.
Sapphire is the hardest of all colored gemstones which makes it a perfect choice for everyday wear.
Another great feature of orange sapphires......is the rich warm hue that goes beautifully with both yellow gold as well as platinum. This is the type of color that can easily look it's best in either metal.
And let's not forget that the Pantone 2012 color of the year is Tangerine Tango.
Need I say more? Okay....then I will.
Fancy Orange Sapphires like The Great Pumpkin shown above are the perfect color for redheads and brunettes. Did I mention that I am a redhead? I guess that makes me biased, but yes, this is still a gorgeous color that is worthy of an exceptional custom ring, brooch or necklace.
I'm thinking it would look best in a stunning ring design, accented with colorless diamonds and perhaps some small fancy purple sapphires, but of course, any number of designs is possible.
If you think this is a great stone for your loose gemstone collection or perhaps you would like to discuss a beautiful custom jewel project featuring this stunning gem, please send me an email. I would love to help you create a magnificent jewel featuring one of my favorite gems.

Progression of a Design
Clients often ask me how I come up with a design.
- Do I seek inspiration from a specific gemstone?
- Or do I have the design already in my mind and look for the best gem for that design?
- Do I take an existing design of mine and modify it to suit the needs and style of a specific client?
- Do I look to the past and study ancient and antique jewels, architecture, textiles, motifs and gather inspiration from historical designs?
The first Cool Ice ring I made featured a fine grade 2 carat oval diamond (E, VS1), set low in four heavy gauge prongs, flanked by two trilliant cut diamonds burnish set flush within the shoulders of the band. The ring itself was a thick, heavy and brightly polished smooth band that was as wide as the base of the trilliant diamonds and tapered in width to form a gentle dome style ring.

Some clients desired a more rounded, softer edge dome style ring where as others requested a sharper edged band with a flatter profile for a more geometric approach.I love the stark combination of the platinum and rose gold stripe along with the soft satin finish we applied to the metal surface.
One day, a client approached me about my Cool Ice design, but his "fiance-to-be" loved sapphires. Since blue is her favorite color, he wanted to feature a rich blue oval sapphire in a ring based on our Cool Ice design. This was the beginning of my Cool Blue series.
Cool Blue lead to another version called Horizontal Blue, when a young couple wanted an oval Tanzanite set horizontally. I chose fancy yellow side diamonds for this ring as yellow is a complementary color to blue-violet. I also suggested a sturdy bezel setting for additional protection to the Tanzanite which is not as hard as sapphire or diamond.
The original Horizontal Blue was made with a matching contoured wedding band. But I have also made matching contoured wedding bands for the Cool Blue and the Cool Ice rings. And don't miss the Concave Facetted Horizontal Sapphire Ring which is really striking or the Mini Horizontal Blue for a more diminutive look.
So what's next ? Horizontal Violet of course !

I have yet to create this with an orange or pink sapphire.....any takers out there? I think this design would be fabulous with a bright pink gem !

If Red is your thing........how about a Horizontal Red Spinel to grace your finger. This example features an intense Fire Engine Red cushion cut red spinel in a brightly polished bezel.
I could go on and on and on ! But I think you get the picture. The Cool Ice.....Cool Blue.....Horizontal Blue design can be made with oodles of variations to suit your personal style and taste.
The options are endless.......limited only by our imagination.
For more information on any of these rings, click on the photos for links to my website with additional photos and details of these rings.
I am also happy to discuss with you a custom Cool Ice.....Blue, Horizontal...or whatever your fancy. Just send me an email.
Until next time.....

Drusy Gemstones - Glistening Wonders
Drusy is a term derived from the ancient Greek word "drossos" meaning "dew" which later evolved to the Bohemian "druza" and was then transformed by the Germans to druse. Some think of drusy as dew drops atop a mineral but I prefer to think of drusy like fine sugary crystals glistening as if freshly fallen snow on a cold winter morning.
Drusy is basically a layer of micro-crystals (i.e. tiny tiny tiny) that have formed on the surface of a mineral or matrix.
It can be seen on a variety of colors of Quartz (white, orange, yellow, blue, mauve, etc.) found world wide, as well as on vivid green Uvarovite Garnet from Russia, hot pink Cobaltocalcite from the Congo, bright turquoise colored Chrysocolla from the Southwestern United States, Brazilian Rainbow Hematite, deep black Psilomelane from Germany and Irridescent Pyrite from Russia.
From the side, you can see the undulating depth of this lush drusy chrysocolla and the banded layers of malachite forming the side walls. Chrysocolla and Malachite are both copper based minerals that often occur together in the same matrix. Combine the rich copper generating hues of these two gems with a glittery, sugary layer of drusy and you have a spectacular prize.
These dynamic earrings feature Drusy Uvarovite Garnets and took home first place in a design competition.
If you look closely, you will see that the surface is encrusted with dodecahedron-shaped crystals in various sizes. This occurs because Garnet crystallizes in the Isometric (Cubic) system which typically presents as dodecahedron external shapes. The intense green is caused by Chromium.
When purchasing uvarovite, look for specimens that have good surface coverage (no bare spots), intense color and well formed crystals.
Surprisingly, almost all of these materials are natural, even the vivid colors seen in Chrysocolla, Uvarovite and Cobaltocalcite. These truly are nature's wonders !
Cobaltocalcite gets its super hot pink coloring from Manganese.
I would call these "hot hot hot ! "
Irridescent Pyrite has a natural metallic shimmer of vibrant hues that remind me of exploding colorful fireworks ! The intensity of the hues is mesmerizing.
This assymetrical tongue with sweeping bands of color would be dazzling as the centerpiece of a custom necklace. I can envision a warm yellow gold frame along the body of the pyrite with a curved line of facetted rainbow gemstones forming a cross-arm at the top, culminated by a round brilliant diamond as if to mark an exclamation !
Of course there are endless possibilities for a custom jewel featuring this exotic gem. I see this irridescent pyrite set in 18kt yellow gold, brightly polished. But a cool white platinum design with satin finish would be equally striking. You can easily let your imagination wander with gems like this.
There are also some forms of drusy that are treated.
Titania is drusy on quartz that has been coated with Titanium to create vibrant rainbow colors. Black onyx drusy is quartz drusy that has been dyed.
And yes, there is even drusy that is coated with 23 karat gold or platinum.
Will wonders never cease ?
One of the reasons I love drusy gemstones is that they are available in such a wide variety of shapes, sizes and colors. I am able to create truly unique jewelry with these glistening wonders ! Here is a gorgeous Titania coated drusy gemstone I used for a striking custom necklace. This Titania Agate has a metallic blueish border surrounding a pocket of glowing micro-crystals in vibrant purples, blues and yellows.
I designed a pendant for this Titania Agate with a highly polished platinum frame that follows the natural contours of the gem.
The oversized bail was then accented with a trillium cut neon blue Apatite (yes Windex-like color) and a small diamond for added brilliance.

Even the backside of this necklace is unique !
Of course mixing various drusy colors and gem types is permissible. These fabulous earrings showcase a pair of pie shaped vibrant rainbow hematites atop drusy yellow quartz trilliums. The round facetted rhodolites compliment the pink hues in the rainbow hematite.
These gems and much more are available in our gallery for purchase. I work with a wonderful assortment of drusy gems that can be incorporated into a custom jewel of your liking. You can choose from a great number of colors for the combination that best fits your style.
