What is Sterling Silver?

Posted in Metals at 7:51 am by diamonddude1

John had asked out of curiosity what is sterling silver?

Sterling silver is silver that by composition is 92.5% silver and the rest are other metals alloys. Commonly copper is used as the alloy. Pure or fine silver 99.9% is much to soft to be  used practically for jewelry purposes. Alloys are added to increase hardness and still allow malleability.

Other alloys used is the metal geranium, platinum and zinc which are primarily used to reduce tarnishing but also to improve silver’s workability.

Sterling silver can be identified by 925 stamped on the jewelry piece or the words Sterling Silver.

The Charm of Charm Bracelets

Posted in Metals, Mountings tagged , , , at 5:14 pm by diamonddude1

Julia recently came in to add another charm to her bracelet. It is an unscheduled ritual that every time she returns from a major trip she adds a new souvenir charm to her bracelet.

Some may think that charm bracelets are passe. For others it is a collection of important memories.

Some people have a charm bracelet that is a travelogue of their all the places that they have been to a wonderful reminder of the how big the world is.

Others have charm bracelets that are more personal in nature. They may have hearts with names of their children or grandchildren, charms of their pets, anything that has that personal connection to their memories.

Charm bracelets are any chain bracelet that has links that are large enough to attach a charm. It can be made in gold, silver or even in metal that is not precious.

Charm bracelets are endearing for the things that it represents to the owner. It is an accumulation of all the things we should be grateful for.

The Many Choices In Men’s Wedding Bands

Posted in Diamonds, Metals tagged , , , , , , , , , , , , , at 7:04 am by diamonddude1

Chad came in looking for a wedding band and was astounded by the choices set before him. Men’s wedding bands were seen as kind of an afterthought. There are innumerable ring choices for women, but men, until recently were left out of having as many choices.

Now there are a greater number of choices in materials that are not the traditional choices of gold, silver and platinum.

Men now have other metal choices such as tungsten, titanium, palladium, stainless steel, and ceramic.  There are even combination of these different materials to create even more ring designs like mokume. Diamonds and gemstones can even be added for more bling.

It may actually be difficult now to choose a ring because there are simply too many choices, but having choice is much better than having none. Enjoy the quest.

Are All Ideal Cut Diamonds the Same?

Very little light loss (red) in a nice ideal cut diamond

This question has been posed by several people from time to time, and most people think it is true.

The answer is no, they are NOT all the same.

The actual answer is more complicated. On paper based on the certificates they come with they may appear to be the same but there are differences.  Sometimes the differences are major.

Even AGS (American Gem Society) and GIA (Gemological Institute of America) two of the most accurate and respected grading laboratories do not have the same criteria to determine the ideal cut. It is our observation is that AGS is stricter in their cut grading than GIA.

There are several machines that will visually assess light return and light loss in a diamond. They are the Idealscope, Firescope, our Diamond Photoscope and equipment by GCAL (Gem Certification and Assessment Lab).

Using these equipment you can actually determine which of several ideal cut diamonds are better. The range can actually be quite diverse and with the naked eye once you know what to look for you can actually see the difference.

To choose just by looking at the certificate information is not the best method to buy your diamond if you are looking for the nicest one. You should have someone with access to one of the previously mentioned equipment to verify the best light return before you pay for that diamond if you want the most beautiful, brilliant, fiery diamond.

President Obama Renews Ban on Myanmar Imports

Posted in Uncategorized at 10:40 pm by sweetmomentsbythediamondspecialists

President Obama signed the bill passed by the U.S. Congress to renew the ban on imports of jade and ruby from Myanmar.

In 2003, human rights groups pushed for this ban to stop financing the military junta in Myanmar. They claimed that the military were mistreating the miners, underpaying them, and using the funds to build their weaponry supply.

In 2008, this ban was extended to Myanmar goods that were cut and polished in third world countries such as Thailand.

A group of jewelers, including the American Gem Trade Society requested a release on the ban claiming that the miners were the only ones being hurt by it. Artisianal miners, already poor, were losing their jobs and were not able to care for their families.

Apparently, the U.S. Congress and President Obama disagreed.

How Much Should I Pay for a Gold Ring?

Posted in Metals, Mountings tagged , , , at 10:05 am by diamonddude1

This question was asked by Lacey and it is not as simple as it seems.

The short and sweet answer would have been that the best value would have been the lowest price per gram for what ever karatage gold you were interested in.

What makes this answer difficult is that value is not just based on weight alone. The design factor has to be taken in account along with the labor cost to make it and the personal aesthetic choices of the person.

Some rings are more intricate in design and takes longer to make. Some are made by machines but it has to be programed, manned and the cost of the machine becomes part of the cost of the product.

One of a kind custom design rings may cost more because of its uniqueness. Designer rings are exclusive designs whose value may be based on the personal appeal of the buyer.

The long answer is that if you take everything in account based on the weight of the ring and its design and your personal appreciation of it, thenThe best value is the one that you feel for what you paid is the one that makes you feel the happiest even if it is not the least expensive one.
