Lingo and abbreviations in the Diamond, Gemstone, and jewelry industry. |
| 6/27/2009 7:54:30 PM |
Today, more than ever, people are shopping online at an ever increasing rate. One disadvantage is that terminology and abbreviations can be used by the jewelry or gemstone seller that you may overlook or not completely understand. Online you have less of an opportunity to ask a quick question to a salesperson. This could come back to haunt you if you find out that a Diamond has been enhanced or a gemstone was synthetic and you didn't recognize the "lingo" or "abbreviations" that the seller was using. Sure, he may have been trying to pull one over on you while covering his bases, but in the court of law your apeal may not stand if his use of abbreviations of treatments is an industry recognized standard.
This segment is going to break down 3 particular groups ( Metals, Diamonds, and Colored Gemstones) and cover the meaning of popular terminology or abbreviations in each group. Hopefully this will help arm and prepare you for your next round of shopping. Armed with this knowledge you'll be more confident, and relaxed, when shopping for that valuable piece of jewelry.

I Wear Designer Clothes When I Want To Shine |
| 6/26/2009 8:50:47 PM |
 How important are designer clothes to you? The answer to that question probably depends on who you are and what you do for a living. For me the importance of designer clothes very much depends on the situation. If I am going to the store for some milk or working from home on my computer then I do not bother with designer clothes or even brand names. However if I have an... Read More |

Birthstones |
| 6/2/2009 6:54:16 PM |
Birthstones | | 6/2/2009 6:49:35 PM | Let's face it, the birthstone idea is all about promotion of certain stones in jewelry stores.This is fine but the list constantly seems to change and now there aremultiple stones for some months. The chart shown below needs to havesome changes made:
The most confusing months, even for many jewelers, are December,November, October, and June. The rest are pretty straightforward. Thefollowing are the changes that need to be made:
1: June- The additonal stone is Alexandrite. This gemstone is a rare, color change Chrysoberyl that is found in Russia, Brazil, and parts of Africa.
2: October- The additional stone is Pink Tourmaline.This stone, primarily found in Brazil, can be expensive in the highergrades and larger, clean gem material. For the most part it isaffordable in the smaller sizes.
3: November- The additional stone is Imperial Topaz.Imperial Topaz will have a peachy yellow color and is not a gemstonefound at your average mall or diamond oriented jewelry store. Thisgemstone was the ORIGINAL BIRTHSTONE until someone decided that Citrinewould be an easier sell and put it in it's place.
4: December- This month has THREE stone choices. Everyone assumes that the main one is Blue Topaz. They are wrong. Originally it was Blue Zirconwhich is not to be confused with Cubic Ziconia....which is a man-madestone. Blue Zircon is a beautiful stone that has very high brillianceand refraction. It's primary source is Cambodia but can be found inother places. Again, Blue Topaz was added since it is more affordableand easier to sell commercially. The latest addition is very popular. Tanzanite was added as a December birthstone just a few years ago. It is a bluish-purple stone in the Zoisite family.
I hope this article has helped you in your desisions about birthstones and their many substitutes.
