The Silver Cuff-Plus - Key Trend from Couture Las Vegas

Key Trend from Las Vegas Couture Show June 2012: The Silver Cuff-Plus

American Estate Jewelry reports a strong showing of silver cuffs from the June 2012 Couture Show, the annual jewelry event hosting 300 of the finest couture jewelers. A key trend in silver bracelets was the silver cuff-plus. The plus comes from uncommon mix-ins of gold touches, precious stones and nature-inspired texture. American Estate Jewelry offers an extensive collection of silver cuffs plus, all made in the U.S.A.

Based on trends from the June 2012 Las Vegas Couture Show, American Estate Jewelry reports a strong growth of interest in the silver cuff. The annual jewelry event, exclusively hosting the top 300 U.S. couture retail jewelers, revealed a new appeal of silver cuffs-plus. The plus means that, though the bracelets are made largely of silver, designers are now taking a fresh approach, adding precious stones, gold touches and nature-inspired textures. As July 4th draws near, consumers can enjoy cuffs-plus from American Estate and feel pride knowing they are made in America.
At the Couture Show, precious stones were featured in designs by Katie Decker, such as an openwork sterling cuff with white sapphires, retailing for $1,563. Lauren Harper won a Couture Design Award for her matte sterling cuff rimmed with moonstones and white topaz in three bands. 
Tiny Jewel Box, one of America's top couture jewelers, favors American Estate's handcrafted, exquisitely detailed Chrysanthemum Cuff with Cabochon Sapphires for $750 and its Bamboo Cuff with Natural Turquoise for $920. The Bamboo cuff and accompanying pieces are also available with large, faceted natural crystal quartz. Particularly popular in DC is American Estate's Cherry Blossom Cuff with Pink Tourmalines.
Silver cuffs-plus were also featured in Buccellati's couture collection. Its blossom cuff with gold exterior touches, made in Italy, is offered at Bloomingdale's in NYC for $1,300. Works Gallery, also on the upper East side of Manhattan, showcases The Three Bloom Peony Cuff, handcrafted by Galmer in America. Created using the rare repousse' technique, the cuff features three plump sculptural blooms, gold textured centers and romantic openwork, for $750. As part of the American Estate collection, all made in the USA, Galmer has also touched 24K gold on the exteriors of The Wild Iris Cuff and The Touch of Gold Peony Cuff. Additionally, the Galmer signature is a 24K gold lining inside every cuff in the collection.
Smooth silver cuff surfaces were not in evidence at the Couture Show. Instead, the textures of nature were abundant in Buccellati's collection as they are in American Estate pieces. Buccellati's vine leaf cuff for $1,200 features tiny same-sized leaves forming a geometric impression. Galmer's Vineyard Cuff recently introduced by American Estate for $725 also features natural textures, and openwork between large grape leaves beautifully veined. The Palm Cuff features sensuous linear detail.
In the past, the Couture show was dominated by gold and large gemstones. Now luxury silver is welcomed due to exquisite design and expressiveness. Silver designers' creativity and experimentation is allowed, in part, by the lower cost of silver vs. gold. Why the silver cuff? Carolyn O'Keefe, founder of American Estate Jewelry, offers two reasons. First, the bold elegance fits the American woman's confident style. And, second, O'Keefe notes, "The silver cuff is an American legacy."    
In the 1900's the American Stieff Company created its classic repousse’ rose cuff by rolling sterling silver over a molded surface. Today Tiffany offers its cherubic cuffs created by the same technique using original molds from the turn of the century. Galmer revives this tradition with changes today’s women seek. It’s the classic American cuff done several notches better with a snug, more comfortable fit, tapered edges, a higher, sturdier silver weight, sophisticated floral designs and the new "plus" features so popular at Couture.

#GemCutters - Intro to Gem Cutting and Recognizing A Well Cut Gem

I have been planning this series of blog posts since the Tucson Gem Show where I had the privilege of getting to know some extremely talented Gem Cutters...well I have finally found the time!

We are going to talk to and feature the work of some of the most important Gem Cutters of our time, but before we get started with that we need some information so we can assess the work we will be seeing in the weeks to come.

So - let's get this ball rolling with a couple of videos by John Dyer.  

First up - we are going to learn to distinguish a Well Cut Gem from a Poorly Cut Gem.

I love John's Tutorials because he is so easy to follow and can convey technical info with out losing his audience.

Now that you have the knowledge to chose a cut gem - lets look at a brief explanation of what goes into cutting a gem.

I will be featuring John Dyer and his work in a future post but I want to give you a little information.  I always want to know why I am listening to what someone has to say...

In a 2004 article for Professional Jeweller Magazine, famed Gem & Jewelry Photographer, Robert Weldon described John this way.
"John Dyer has achieved the highest pinnacles of success in gem cutting despite – or perhaps because of – his modest nature. Free of the bounds of arrogance and self-importance, he pursues beauty for beauty’s sake. Along the way, he’s won multiple American Gem Trade Association Cutting Edge Awards. And the 25-year-old has done it all since embarking on the colored gem path less than a decade ago.
“That kid is so young and so talented,” says Gary Dulac of Gary Dulac Goldsmiths, Vero Beach, FL. “When we met at the Tucson Gem and Mineral Shows just a few years ago, I was impressed with the quality of his work and his humble, open personality. He has come to know my needs and invariably recommends a gem that works perfectly with my designs.”
Other jewelers share Dulac’s enthusiasm. Don Fane, goldsmith for Robert Giede Designs, Menomonie, WI, says Dyer’s gems are easy to set because they’re perfectly symmetrical and that they’re so well polished they look exceptional in jewelry."
The very next year in 2005 John swept the entire Faceting Category at the AGTA Cutting Edge Awards...and has walked to the podium to collect an Award every year since.  John has through all the accolades, managed to maintain his integrity and humility, always willing to  offer helpful tips and support to new cutters.

Michael Stars' "Giving Keys" Support The Homeless

This Saturday, June 23rd, Michael Stars will be hosting an afternoon of wine, appetizers and custom-key engraving in support of the Giving Keys

Guests will be able to purchase a blank key and chain and the Giving Keys staff will be available in-store to hand-engrave an inspiring word of the shopper’s choice onto the key.

Each custom necklace is available for $38 and helps to employ the homeless. 

The Giving Keys are meant to be worn for awhile and then passed on at some point to a person whom you feel could benefit from the message on the key. 

See you this Saturday (June 23rd) from 12-2pm and bring your friends! 

You know this story, it has been on the local news...

About The Giving KeysI met this sweet homeless couple on Hollywood Blvd who have had a really tough life. After falling in love with their hearts, and how hard they're working to try and change their lives, I had an "Ah-Ha moment." I realized they were the missing link to The Giving Keys. So I asked them to be my business partners.  After all, the whole concept is PAYING IT FORWARD.

About The CauseProceeds go to keeping Cera & Rob off the streets and in transitional homes and programs that will educate them so they are able to earn a "living wage".  Once we complete that goal, we will use the extra money to donate to the shelters & transitional homes that were most effective in supporting Cera & Rob.

JTV Partners With Gem-A on Education Project

Jewelry Television and Gem-A Partner to Educate Consumers on the World of Gemstones

Retailer collaborates with the world’s longest established gemological institution to offer exclusive gemstone courses

Jewelry Television® (JTV), the nation’s leading broadcast retailer of jewelry and loose gemstones, has entered into an agreement with The Gemmological Association of Great Britain (Gem-A) to develop a proprietary course for the shopping retailer called ‘Gem Basics’. The online course will introduce consumers to a wide variety of gems and explain the basics of gemology and gem identification. The course also covers gem origins and lore, and will include a basic kit of gem identification tools and a selection of gems.
Quote startJTV’s ‘Gem Basics’ provides an entry-level course for beginners and hobbyists, but also provides a stepping stone for more-advanced studies through The Gemmological Association of Great Britain.Quote end

“Gemstones play an important role in our culture,” said Jerry Sisk, graduate gemologist and co-founder of JTV. “As the largest retailer of loose gemstones in the world, we felt a strong obligation to take a leadership role in the education of our viewers as well as the general consumer. To that end, we developed an extensive Learning Library and made the decision to partner with one of the world’s most respected gemological institutions. It is our express belief that a better-educated consumer will make more well-informed decisions, and will purchase with greater confidence. JTV’s ‘Gem Basics’ provides an entry-level course for beginners and hobbyists, but also provides a stepping stone for more-advanced studies through The Gemmological Association of Great Britain. This is a win-win opportunity for the consumer and JTV.”
Gem-A currently offers a range of courses that result in internationally recognized gem qualifications. The development of the Gem Basics Course has been overseen by Dr Jack Ogden, Gem-A CEO and a well-known authority in the gem and jewelry field.
“As the first retailer in the world to sell loose gemstones on television, JTV’s extensive reach has increased the appetite for loose gemstones and colored gemstone jewelry among consumers,” said Ogden. “Gem-A is pleased to help further JTV’s mission of opening the world of gem knowledge to a wider audience.”
Gemology is the science of gems. It encompasses the methods of formation as well as the study of properties and characteristics necessary for classification and identification. Intended for gem collectors, enthusiasts and industry professionals, the Gem Basics course encourages continued learning and a deeper understanding of the beauty and precision of nature.
Sisk went on to say, “As the longest established gemological institution in the world, Gem-A has an international reputation for excellence and we are honored to be associated with them.”

Green Gem Foundation - This is What FAIRTrade Is About!

6.20 ct Tanzanian Chrome Tourmaline by David Dawson
Green Gem Foundation is a fledging organization composed of a group of artists and gemstone dealers making a grassroots effort and working cooperatively towards a common goal. 

The goal is defined as connecting the artists and dealers in gem producing countries with the consumer.

This sustainable model is the future of the gem trade. It is already happening.  Across Africa the values of sold stones in the West are now widely known — Internet access has provided a level playing field.

The model of exporting raw materials then marking those materials up is changing, and will continue to change. At the consumer level it's the added ethical component that shows true sustainability — it is a message understood at the gut level.

The Green Gem approach is simple we are working to add value at the source. We are not concentrating on giving back programs, training, or any approach that does not support this increased added value. We are interested and will address a need if we see it, but our emphasis is to help to provide direct market access thus supporting infrastructure by bringing more cash into the country. Not through the hands of a few but through everyone's hands at all levels.  Cash provides sustainability — it comes without conditions, it arrives direct.

Diamond - in Kenyan Zircon
The gemstone market is huge.  We recognize that we represent one small sphere of influence.  The traditional flow of gems will continue for some time, but with increased market access this tradition will change.  

As we continue to organize as a company, moving forward, more and more people are stepping up.  Green Gem is currently a non-profit — and while we are working toward our charitable 501(c)3 status donations to us are not yet tax-deductible.  The organization is looking for committed individuals to bring unique talents to the table.  We are past the core planning stage and the work lies ahead.

Let us know how you would like to get involved, you can reach us through our website.
