Estimating Carat Weight And Effect Of Carat Weight On Gemstone Price

May 14th, 2009

The carat is a unit of measuring the weight of a gemstone. One carat equals 0.2 grams, or 0.007 ounces (avoirdupois). 5-carats makes 1 gram, 10-carats makes 2 grams and so forth, and 141.7 carats makes 1 ounce. The carat weight is measured in points or fractions. 100 points makes 1 carat. Explaining with the help of an example, if you buy .50 carats gemstone, then it equals to 50 points or I/2 carat. Ideally speaking carat weight has major affect on the price of the gemstone. There are certain specifications to follow in the carat weight measurement as well. For instance, 1/4-carat total weight may be 0.21 to 0.29 carats; 1/3-carat total weight may be 0.30 to 0.36 carats; 1/2-carat total weight may be 0.45 to 0.59 carats etc.

The best and easiest way to estimate the carat weight of the gemstone is through a gem scale. The scale is marked in carat and grams respectively. Another simple way to measure the carat weight is the postage scale. The scale gives the readings in ounces. Convert the ounces to grams. One ounce has 28.4 grams. After you have converted them into grams, multiply the figure by 5 and you get the estimate in carat weight. Carat weight also holds direct relation with the diameter and the depth of the gemstone. The bigger the carat size of a gemstone, the greater will be its depth and diameter, which will eventually reveal a price estimate for that particular gemstone.

Color, cut and clarity of the gemstone also plays a very crucial role in ascertaining its price and value. A 0.42-carat gemstone with refined color and clarity may cost more than a 0.62-carat diamond having lower color and clarity. However, if you have a gemstone, which is of 0.76-carat, and another gemstone of 0.58-carat, and both have the same clarity and color, the 0.76-carat gemstone will be more expensive. Note that there are other factors that go beyond the carat weight estimation when it comes to estimating gem stone price. If a gemstone of 0.65-carat with a crack in it is compared with a .34-carat gemstone that is greatly refined, then, obviously, the .34-carat gemstone will cost more when compared to the 0.65-carat gemstone.

You need to check that the gemstone has no cracks. It is because cracks also reduce the prices of even the most precious of a gemstone. Try to purchase the evenly shaped gemstones, which have a proper symmetry. If you are not so sure about how to find a crack on the gemstone, try to take the expert’s advice. A slight change in the symmetry will definitely result in reduced price value. These are all possible factors that affect the price of the gemstones.

Information on Loose Pearls

April 20th, 2009

Author: Editor123

Pearls come in a variety of sizes, types, and shapes. A sure way to save money on pearl jewelry is by buying loose pearls which are usually sold by the bulk. To make sure that your wholesale pearls are authentic, you need to understand the basics about these gems first.

Natural and Cultured

Natural pearls are pearls which have been honed without the aid of human hands. These are more lustrous than cultured or farmed pearls because they are fruits of years of natural calcium formations. Cultured pearls are not fake pearls, but are cheaper because they’re easier to produce. While a single natural, well-rounded pearl would cost you your liver (because of its rarity), a whole strand of well-rounded loose pearls is fairly affordable.

To know the difference between a natural and a cultured pearl, you can conduct the old front tooth test. Cultured pearls would feel smooth and slippery when brushed against your teeth, while natural, pricier pearls would be less perfect and feel slightly gritty.

Imitation and cultured pearls

Never mistake cultured pearls for imitation pearls. Imitation or synthetic pearls are usually painted-over glass or plastic beads. They should, therefore, cost a lot less than cultured pearls. To make sure that the pearls you’re availing are real and not synthetic, ask the dealer to scratch his/her knife against the pearl bead. If it’s synthetic, the paint will wear off. If it’s real pearl, the scraped off material should be powdery.

Pearl shapes

Valuing pearls are slightly tricky. The way pearls are graded depends on their luster, their size, and their type. Naturally, rarer pearls cost a lot more. Natural, black, well rounded pearls would probably cost an arm and a leg. Unless you’re an avid collector, you should probably go for cultured pearls which are semi- or well-rounded. Some dealers “dye” their cultured pearls, so they resemble the rarer black Tahiti natural pearls, or the purplish or pinkish hues of deep sea water pearls. The leading pearl farming countries that produce loose pearls are China and Japan.
