The World's Most Expensive Bicycles

Can you imagine paying $114,464 for a bicycle? When it's completely plated with 24 K gold and is embellished with 600 Swarovski crystals you can. There are only 10 of Aurumania's limited "crystal edition" bikes but they can be purchased and delivered anywhere in the world for $114,464. 

The second most expensive bike sold in 2005 for $75,000 at the Lance Armstrong Foundation Gala. This "7-Diamond" bike commemorated Lance Armstrong's 7th victory in the Tour de France. The bike featured seven 1 ct. Gemesis man-made diamonds and 300 white diamonds. 

Gemesis Has Pink – Retail Rollout Expected in Early ‘09

Lab diamond maker Gemesis has announced the beginning of regular production of pink diamonds. This is the firm’s second color range since the commercial production of yellow diamonds was launched

Manufactures are expected to start receiving the rough output by late November of this year, with the first jewelry set with the Gemesis pinks projected to be in stores in early 2009.

Production will start with 1 - 2 carat rough, according to CEO Stephen Lux, though it is understood that larger goods of about 3 carats are expected to be produced at a later stage. The pink lab-created diamonds’ color ranges from fancy purple to vivid pink.

Since Gemesis came onto the market with their range of yellow diamonds, there has been an expectation that additional fancy colors will be introduced. While the company declined to comment, blue diamonds are likely to be offered next.

Gemesis diamonds sell at about a 30 percent discount to natural mined yellows of comparable size, color and clarity. Because of the scarcity of pink diamonds, the discount on the lab-made goods is expected to be less then 30 percent.

Gemesis launches new website

The Gemesis Corporation, producer of gem-quality, fancy color cultured diamonds, has launched a new website that serves as an educational tool for consumers and the trade. The Florida-based company has designed the site to inform the industry about the company, the growth process, general fancy color diamond information and diamond certification. The site also features jewelry brands carrying Gemesis Cultured diamonds.

“We have completely redesigned our new website with a fresh modern look,” says Gemesis President and Chief Exeuctive Officer Stephen Lux. The site can be viewed at http://www.gemesis.com/

Gemesis to launch pinks and blues this year

Gemesis, the cultured diamond producer, said today it expects to launch pink and blue diamonds by the end of this year.

Currently, Gemesis only sells cultured diamonds - diamonds that share the same chemical and physical properties of earth grown diamonds but are grown under laboratory conditions - in yellow and orange.

The Florida-based company said it can currently produce colorless stones, but in sizes that would directly compete with the most prevalent mined diamonds and thus it felt no need to bring a product to market that is so readily available.

However, with predictions of a major shortage looming in larger white goods, the company’s said it is working consistently to grow stones in the 5 – 10 carat range. Gemesis expects these types of goods will be commercially available in about three years.

The supply of cultured diamonds remains extremely limited. Gemesis does not give exact figures, but the company is believed to produce and sell around 100,000 carats per year.

Cultured Diamonds Save You Money

Not that you didn’t know this already, but this article details just how cultured diamonds save you money


Jewelry is always a big seller for Valentine's Day, but for many "diamonds" are not in the budget.

Now there is a new 'type' of colored diamond not found in a mine but grown in a lab.

It's got all the brilliance of a 'natural' stone, but costs a whole lot less!If diamonds are a girl's best friend, a discounted diamond could earn them a spot in the family.

So, for those looking for a fancy colored diamond, cultured diamonds may get you more bang for your bling."

A cultured diamond has the same characteristics as a natural diamond. Same hardness, same refractive index, same brilliance."

But cost about two-thirds less. Why?

Gary Kleinhenz, who is the president of Kleinhenz Jewelers in Westlake says, these diamonds don't come from the ground. They are grown in a lab.

"It's created under the same conditions that diamonds are underneath the ground."

The Gemesis cultured diamond making laboratory in Sarasota, Florida are where the diamonds are made. The process starts with a tiny diamond seed that is placed in a growth chamber. The chamber is capable of generating the 850,000 pounds per square inch of pressure and 2,700 degrees of heat necessary to make one diamond every four days.

"It is just crystals that grow upon crystals to create a larger piece of rough. The rough diamond is sent to the cutter to be polished into what you see in finished jewelry." When you put a cultured diamond on a diamond tester- it registers as a diamond. And when we held it under a blue light, you could see the the seed the diamond grew from, right in the center."

The nucleus of a Gemesis diamond is a piece of diamond.

Right now you can only get them in yellow and orange. Other colors will be available soon. Industry leaders don't expect them to replace the white diamonds everybody loves.

"I think most people want the whitest diamond they can find and fancy colored diamonds are almost for a right handed ring or a cocktail ring, moreso than the engagement ring."

The Gemesis diamonds are certified by the Gemological Institute of America. The key here is to know when you are buying one. Make sure you are dealing with a knowledgeable jeweler who offers full-disclosure about where the diamond came from.
