Loupe Clean Sparkles for Your Valentine

Wednesday, January 13th, 2010

All over the world, Valentine’s Day calls for newer and different ideas to celebrate. Love never fails to fill hearts with thrill and excitement, this very day. No matter people come with unique ideas of romance and love, novelties like jewelry can never outlive.

Along with the most romantic eve of the year, it is also an important commercial day for many companies. Inclusive of online jewelry retailers, they prepare from head to toe, to embellish their customers.

However, people should take care while shopping for such sparkling charms for their beloveds. There are many fraudulent which tend to fool people. They sell imitations or cheaper specimens at the price of real expensive gemstone jewelry.

Therefore, it calls for actual precautions to be taken care of while examining jewelry before buying. Nevertheless, it is not possible for a layman to assess a gem rock like an expert, unless you have a trustworthy jeweler to help. In that case, a loupe comes in handy.

To elaborate on this new term, loupe (pronounced as loop) is an effective kind of a magnifying glass used for many purposes. Even beginners can examine a stone for any unwanted scratches, inclusions, and flaws with it. However, it isn’t necessary that one should be able to identify all kinds of defectives in a skillful manner, like a gemologist could.

Even a basic knowledge is sufficient to use loupe to stop falling prey to any disreputable dealers. Loupe is a practical device which becomes more and more valuable, as one becomes an expert after constant usage. Always go for a 10X which is a correct one. Also known as triplet, it can be acquired from any optical supply.

Selecting a device of such power takes care of two persistent problems. Firstly, hints of colors found on outer edge of the stone and visual errors, also found at the perimeter of lens.  Inclusive of a round black rim is also necessary. It shouldn’t have any fancy color housing like gold or chrome as it can intervene with the stone color display.

With a loupe, one can check out the flaws or inclusions seen in an emerald. Moreover, a genuine one does show such flaws otherwise it’s fake. A ruby is always misunderstood with a close look alike named as spinel. However, the difference can be detected.

Similarly, there are many stones which can easily be identified as real or fake with the help of a loupe. Celebrate this Valentine’s Day with your valentine as you woo her with best and a alluring of your emotions expressed through gemstone jewelry.

How to tell a real diamond from a fake

Sunday, October 18th, 2009

People want to know if there is some simple test they can do at home or little tricks of the trade to tell if the ring they own is a valuable heirloom or of the Cracker Jack variety. Without question the quickest and most reliable method for authenticity would be an independent appraisal. This can be accomplished easily enough by looking under “Appraisal (Jewelry)” in your yellow pages. When you call to enquire about their services you want to ask three questions:

1)      Can you schedule an appointment or is it first come first served.

2)      Ask the fee; $35.00-$75.00 is considered a fair price.

3)      Ask if the jewelry will always be in your presence. If the appraiser says they will not evaluate the jewelry in front of you, find another appraiser.

If spending 50 bucks seems a little too steep to uncover the identity of your rock, you can head to your local jewelry store and ask their in-house gemologist to take a peek and give you their opinion.

Since opinions are like belly buttons (everyone’s got one) understand that in a lot of these quick 30-second evaluations mistakes can be made. Especially since most jewelers won’t charge you for 30 seconds of their time. (Just like with independent appraisals, don’t let the merchandise out of your sight.)

There are some less reliable methods you can try but there are no guarantees with these:

  1. The old “If it will scratch glass it has to be a diamond.” Well, it is true that diamonds do scratch glass but so do a lot of the other fakes on the market. To boot, it’s possible to injure your rock even if it’s real during your hardness test.
  2. The transparency test. If you flip the diamond in question upside down and place it over some newsprint and can clearly read through the stone, it’s not a diamond. (The problem with this test is some diamonds are cut shallow and can be read through.)
  3. The fog test. This test I like a lot. Put the rock in front of your mouth and fog it like you would try to fog a mirror. If it stays fogged for 2-4 seconds, it’s a fake. A real diamond disperses the heat instantaneously so by the time you look at it, it has already cleared up. (A downfall to this test is oil and dirt on the stone can effect its reliability and the test is not accurate at all on doublets where the top of the stone is diamond and the bottom is cubic zirconia epoxied together.)
  4. The weight test. The most popular of diamond simulants (fake) is a cubic zirconia. C.Z.’s weigh approximately 55% more than diamonds for the same shape and dimension. So if you have a carat or gram scale at your disposal you can see if the imposter tips the scales too much.
  5. The U.V. test. A high percentage of diamonds fluorescence blue when put under an ultra violet light (black light). Since 99% of all fakes don’t, a positive identification of medium to strong blue would indicate a diamond. The bad news is if this method proves you have a diamond, it also proves your diamond is worth less. Diamonds with blue fluorescence are as much as 20% less valuable. Remember, lack of blue fluorescence doesn’t mean it’s a fake; it could just be a better quality diamond.
  6. Under the loop test. If you own some sort of magnifying lens, there are some things you can look for on the stone that might give away its identity:
    1. Look at the rock from the top and see how well the facets (cuts on top of the diamond) are joined. They should be sharp, not rolled.
    2. Look at the girdle and see if it is faceted or frosty (a clear sign it’s a diamond) or waxy and slick (an indication it’s a fake).
    3. While you’re looking at your stone under magnification, look into your stone to see if you detect any flaws (carbon, pinpoints, small cracks). These are typically clear indications it’s the real thing, since it’s very hard to put inclusions in a fake.
    4. After examining the stone, focus in on the stamps inside the setting. A stamp of “10K, 14K, 18K, 585, 750, 900, 950, PT, Plat” indicates the setting is real gold or platinum which gives a better chance that the stone in it is real as well. While you’re looking at the interior of the ring, also look for any “C.Z.” stamps that would indicate the center stone is not a diamond.
