These Tiny Diamonds are not for Engagement Rings.

What is a Nanodiamond?

Nanodiamonds are made by detonating two explosive compounds, TNT and RDX, and then collecting the resulting soot – which contains diamonds approximately 4nm in size. But to make the diamonds fluoresce they have to be exposed to a high-energy electron beam from a van de Graaff accelerator, then heated to 800°C – a very costly procedure.

Now comes a new, cheaper process invented by Taiwanese chemists that makes nanaodiamonds fluoresce by bombarding them with high energy helium ions. This results in structural defects to the point that they fluorecse when hit by a laser light.

The practical applications are important. Nanodiamonds could be used as light beacons in chemotherapy by being attached to cancer cells and tumors in the body so that these medicines are more accurately delivered to the target zone.

Carbon based nanodiamonds are water soluble, have good biocompatibility, and cause little inflammation. Research is ongoing to determine toxicity and how long these nanodiamonds will remain in the body before dissipating. Answers to these questions are necessary before full-scale clinical trials can begin.

High Price of Gold Can Make Your Mouth Worth Mucho Money!

The Associated Press reports that people are digging through drawers for old dental caps, fillings and bridgework they saved years ago and selling them at prices that would make the tooth fairy blush.

Instead of hanging on to the pieces as souvenirs, many are turning them over to pawnbrokers, coin shops and specialized firms that buy “dental gold,” hoping to take a bite out of the metal’s historic run to $1,000 an ounce.

“People are really cashing in. If a dentist passes away, their kids come in with a big pile of good teeth,” said Scott Taber, owner of Taber Coins, a Shrewsbury, Mass., coin dealer that buys dental gold and then resells it to a gold smelter.

He said he used to see only a few customers a month selling gold teeth but now gets that many each week. “People are digging up the gold and starting to sell it,” he said.

A gold crown typically uses about one-tenth of an ounce of 16-karat gold, which would fetch around $40 to $50 at today’s prices, Taber said. Heavier pieces of dental gold can command prices of several hundred dollars, he said.

That deal sounds pretty good to people like Ann Davis, a 63-year-old retiree in Rock Island, Ill., who had gold caps and a bridge removed nearly 40 years ago and has held on to them ever since.

“You don’t want to throw it away because it might be worth something,” she said. “Now that gold’s going up it’s time to think about selling.”

Gold prices have been surging since late last year as the weak dollar, record crude-oil prices and fears of a U.S. recession have enhanced its appeal as a haven for investors.

Gold set a record of $1,038.60 an ounce on March 17 and has since fallen to about $920, but experts say it could soon resume its upward climb. Several precious metals analysts have even predicted $2,000 gold ahead as a global commodities boom pushes the price of raw materials further into record territory.

Gold crowns, fillings and bridgework are usually made of 16-karat gold, an alloy that contains other metals such as silver, zinc and copper. That made gold dental work soft enough to shape but hard enough to form a biting surface.

But don’t expect to get rich hawking gold fillings and crowns.

And replacing a gold crown isn’t cheap. Newer porcelain and gold crowns can cost $500 to $3,000 apiece, and not all insurance companies will pay for the procedure.

Besides the financial benefit, Taber says people don’t mind selling dental gold because it’s far less emotional than parting with heirlooms like grandma’s wedding ring or the family silverware.

“I haven’t seen anybody with sentimental teeth,” Taber said.

Diamonds and Ruby Trophy Ring: It’s a Player!

Few of us have the talent/ability to become a Professional sports athlete and so we use our imagination and live vicariously through our hometown teams. All of us have at one time or another fantasized about making that winning shot or play to win a championship and get that Ticker Tape parade down Main Street. One of the rewards is getting that Championship Ring-Bling!!!

The Boston Red Sox, 2007 World Series Champions received their rings yesterday. The new bling – made by the ring kings at Jostens – features a pair of Red Sox, on the top, each one containing four specially cut rubies for a combined weight of 2.14 carats.

There are 14 princess-cut diamonds in a diamond-shaped bed below the Sox, and 28 more round-cut diamonds running around the top of the ring.

Eight players – David Ortiz, Manny Ramirez, Jason Varitek, Curt Schilling, Tim Wakefield, Doug Mirabelli, Mike Timlin, and Kevin Youkilis – received rings that featured the Sox’ “B” and two World Series trophies on the side because they were on the team in both 2004 and 2007. The rings for the rest of the team feature just one trophy.

On the other side of the ring are the words “7th Word Series Championship,” with a replica of Fenway Park underneath and the words “4-0 Sweep.”

The rings have been appraised at $20,000 and the Sox Team Officials are expected to hand out about 50 of them to players, coaches and staff.

Jostens also made all three of the New England Patriots Super Bowl rings, and are ready to design a ring for the Boston Celtics should they win the NBA Championship this year.

For the rest of us? Dream On!
