A diamond measures a 10 on the Mohs scale of hardness, making it the hardest natural substance known to occur on Earth. This raises the question of how the stones are cut if they are so hard. There are a number of techniques used in diamond cutting, including basic cleaving and the use of a grinding wheel called a scaif. These techniques have been developed over centuries of jeweling, and most cutters use techniques that were originally developed hundreds of years ago, because they are still the best way to handle the gems. Diamond cutters usually combine several processes to create a sparkling, faceted gem from a rough stone, in a painstaking job where the stone may lose as much as 60% of its weight.

The most ancient cutting process is cleaving. To cleave a diamond, the cutter places a chisel at a point of weakness in the stone and taps it with a mallet, causing the gem to split. If the weakness was misjudged, this can destroy the stone. If the diamond cutter judged correctly, the stone will be split into workable pieces which can be individually refined. Medieval gem cutters cut their cleaved stones with other diamonds, lubricating the surfaces with oil and grinding away at the stone to reveal facets. Some cutters still use other gems as part of their cutting and polishing process.

In the 15th century, the scaif was developed. A scaif is a polishing wheel that is kept liberally lubricated with oil and diamond dust. A cutter can use a scaif to polish a gem held in a dop, a padded holder that protects the stone while it is being worked on, only revealing the side that is currently being polished. The scaif changed the face of diamond cutting, allowing cutters to create symmetrical and even facets that bring out the true sparkle and shine of the gem. By playing with angles, cutters created unique and beautiful gems for setting in jewelry.

In the 20th century, another tool was added to the diamond cutting arsenal: a diamond saw. These saws are steel blades that are lubricated with an oil and diamond dust mixture that is continually reapplied as the stone is worked. Because the saws can generate a great deal of heat, the stones may be cooled as they are worked on in special cooling holders. This is also the case with a scaif, and is one of the reasons that cutting the gems is such a painstaking process, because the cutter must take a break every time the stone starts to warm up. If the stone contains any water in small bubbles or hairline cracks while it is being cut, the heat can cause the water to boil, and the gem may crack or explode.

Riches and Excess:

A cousin to yellow (and orange and brown) is gold. While green may be the color of money (U.S. money, that is) gold is the color of riches and extravagance.

Nature of Gold:

The color gold shares many of the attributes of yellow. It is a warm color that can be both bright and cheerful as well as somber and traditional.

Culture of Gold:

Because gold is a precious metal, the color gold is associated with wealth and prosperity. While all that glitters is not gold the color gold still suggests grandeur, and perhaps on the downside, the excesses of the rich. Gold is the traditional gift for a Fiftieth Wedding Anniversary while gold-like bronze is for the eighth and copper with its reddish-gold tones is for the seventh.

Using Gold:

Add a small amount of metallic gold ink to a project for a special, rich touch. Bright gold catches the eye while darker subdued shades of gold lend richness and warmth.

Using Gold with Other Colors:

Add a golden glow to an earthy palette of orange, green, and brown. Double the riches of a burgundy red or purple palette with glittery gold.

Language of Gold:

The use of gold in familiar phrases can help a designer see how their color of choice might be perceived by others, both the positive and negative aspects.

Good gold

• Gold star - praise, commendation
• Good as gold - valuable, positive
• Solid gold - superior, outstanding, best of the best
• Gold standard - the best, a measure of quality, excellence
• Golden child/boy - favored person
• Bad gold
• Gold brick - trick, cheat, or deceive
• Golddigger - someone who feigns genuine interest but is only after a person's money
• Fool's Gold - mica, anything mistaken for gold, worthless
• Gold Words: These words are synonymous with gold or represent various shades of the color gold.

Goldenrod, yellow gold, honey, bronze, copper

Good evening Ladies and Gentlemen:

Here are your numbers for Thursday, Feb 28.2013:


For gold it looks like 149500 oz will stand as that is the OI for March. (1495 x 100 oz per contract)
Or 4.6 tonnes of gold, which is extremely high for a non delivery month.

The total OI for the gold complex was up only 458 contracts.

Gold Buyers

The OI for April  lowers from 247,653 down to 244,812.


\In silver:  total OI rises to 145,388

The OI for the upcoming MaRCH  contract falls dramatically down to 2597.

The next delivery month of April rises to 76,682 from 70,980.

The volume today was good at 47,026.

The amount of silver that will stand for delivery is only 12,985,000 oz.

The data seems very weird.


Preliminary data for this morning.

Open interest for entire silver complex from 153,319  down to 145,620
Open interest for the front March contract month  9411 contracts or  47,055 ,000 oz
Volume yesterday in silver  78,901


and the first day notice deliveries  799 or 3,995,000 oz


Data for gold:


Open interest falls to 433,750  from 439,990

Open interest for the front March contract:  1,499 contracts or 1,499,000 oz

Open interest for the next May contract  247,653

Volume  184,695 contracts

First day delivery notices:  1,383 contracts or 138,300 oz or approximately 4.3 tonnes of gold

March being a  non delivery month.

Since we had major shortcovering on a high gain in silver and gold price, the OI data seems very suspect.  For the OI in silver to fall so badly during a huge gain just does not make sense.  It looks to me like they are fudging the data.

I will report very late tonight to you  (probably in the early morning hours) on first day notice

World’s most popular gold bullion coins

Gold Buyers

Since their introduction in 1986, more than sixteen million Gold Eagles have been sold. Because American Eagle Gold Bullion Coins (their official name) are the world’s best-selling gold bullion coins, they provide instant liquidity. Still, the Krugerrand is probably the world’s best known gold bullion coin.

American Gold Eagles come in four sizes: 1-ounce, 1/2-ounce, 1/4-ounce, and 1/10-ounce. The 1-oz Gold Eagles are by far the most popular and sell at small premiums over the value of their gold content. The smaller coins sell at higher premiums.  Gold Eagles are minted at the US Mint’s West Point, New York facility.

American Gold Eagles are 22-karat gold, which means they contain 91.6% gold and 8.4% of a copper-silver alloy. Because Gold Eagles are 22-karat, many investors incorrectly believe that Gold Eagles have less than an ounce of gold. This is not so.

Gold Eagles: exactly 1-oz ounce of gold
The 1-oz American Gold Eagles contain exactly one ounce of gold, and the smaller fractional-ounce Gold Eagles contain the gold content stamped on them. The copper-silver alloy causes the coins to weigh slightly more than their stated gold contents.

American Gold Eagles: legal tender gold coins
American Eagles are legal tender coins, but their face values are symbolic, as Gold Eagles do not sell at their legal tender values; Gold Eagles sell at prices that reflect the value of their gold content plus small premiums for being coins.

American Gold Eagles: four sizes
The 1-oz Gold Eagle coins are $50 face value, the 1/2-oz coins $25, the 1/4-oz coins $15, and the 1/10-oz coins $5. One-ounce Gold Eagles come in tubes of twenty but can be bought in smaller quantities.

All four American Gold Eagle sizes carry the same design. Gold Eagles minted 1986-1991 are dated with Roman numerals. In 1992, the U.S. Mint switched to Arabic numbers for dating Gold Eagles.

If you would like to discuss buying American Gold Eagles, or would like to discuss any aspect of investing in gold, call us at 800-528-1380. CMIGS takes calls 7:00 a.m. to 5:00 p.m. MST, Mondays through Fridays.

Notes:
The troy ounce is the unit of weight for precious metals. One troy ounce equals 1.09711 regular (avoirdupois) ounces. Where ounce and ounces are used in this Web site, they mean troy ounce or ounces.

Sell Diamond Earrings - Is Facebook Identity the Key to Concert Ticket Sales?

We’ve all had the experience: You favorite musician is finally going on tour and there’s a concert in your area. You want good seats, so you queue up at your computer to be among the first to buy tickets. However, within seconds of the on-sale time, all the good seats are sold out – sometimes the entire show is sold out. You can still find those tickets, but only on the secondary market from ticket brokers who usually charge a 3X or more markup. What the heck happened?

The practice is called ticket sniping. Think of it as ticket scalping on steroids. It’s where brokers use sophisticated software to game Ticketmaster (and other) systems so they can cut the line and buy huge blocks of high-value tickets. It’s been going on for years and while ticket brokers and others get rich, consumer frustration grows. Counter Measures

Ticketmaster has not sat idly by. Back in 2008, it successfully sued sniping technology creator RMG Technologies. It also started using CAPTCHA technology in an effort to slow down the software and force ticket consumers to prove they are in fact real people. This year, Ticketmaster introduced online ticket reselling for Live Nation, a move that may further undercut third-party ticket brokers by providing some competition.Upstart online event management and ticket agency Eventbrite, which allows virtually anyone to sell tickets for their events (conferences, small concerts), also sells tickets to increasingly large events, including the upcoming Governors Ball concert. [Full disclosure: Mashable uses Eventbrite for some of its own events]

Back when the company secured $50 million in funding, Founder and CEO Kevin Hartz (pictured) was hesitant to say it was ready to take on the biggest names in the business, like Ticketmaster."We have this worldwide market," Hartz said, "In a lot of ways it doesn't make sense to fight it out with one competitor. There's a much broader opportunity."Now, however, Eventbrite may be thinking about taking Ticketmaster, and ticket brokers, head on. Making It Better

Hartz maintains that the prevalence of ticket sniping and speculation (buying large blocks of tickets based on, for instance, how they think a sports team might perform in the coming season) is “a failure of innovation” in the ticketing industry.
The ticketing industry also remains something of a black box. Hartz told Mashable, “One needs to illuminate the industry to understand the dynamics of it to prevent abuse….

Diamond Buyer - Security Flaw Gives Hacker Full Access to Facebook Profiles

A web developer claims to have discovered a Facebook security flaw that could have allowed him access into any part of a stranger's profile.

Don't panic: Facebook has already fixed the problem. The developer, Nir Goldshlager, notified the social network about the issue and waited until it was resolved to go public with his discovery. He explained how it worked in a blog post published Saturday morning.In the post, he says he was able to tweak the service OAuth, used by developers to obtain various permissions their apps need to run — for example, location data from your profile page. Goldshlager was able to manipulate OAuth so a visitor to a Facebook page could get full access — to inboxes, private photos and videos — with no expiration.

He notified Facebook's security team and the security flaw has been fixed. He adds, though, that many parts of the exploit stopped working if the affected user changed the account's password.
