You may think you're an expert at spotting fake jewels, but with some of the new diamond facsimiles on the market, even a jeweler might not be able to spot the imposters.

1.Ask if the stone is a genuine diamond or if it is a cubic zirconia, moissanite or other synthetic substance. A reputable jeweler will give you an honest answer.

2.Look at the setting and mount. Since stones such as cubic zirconia are so much cheaper than diamonds, they are sometimes set in inferior metals.

3.Check the wear and tear on the stone. A cubic zirconia is not as durable as a diamond and may show signs of scratches or nicks.

4.Take the stone to a trusted jeweler. Looking through a jeweler's loupe, he or she should be able to spot a fake stone right away. If the jeweler cannot tell by examining the stone, he or she will have instruments that can verify its authenticity.

5.It is highly recommended that you obtain a certificate from the Gemological Institute of America (GIA). The GIA, the largest impartial diamond grading authority in the world, issues a grading report after it examines the diamond and details it specifications.

6.Have the stone appraised by an independent appraiser who is affiliated with a professional organization such as the American Society of Appraisers (ASA). Ask for a certificate indicating the value and characteristics of the stone.

Jewelers make rings using all types of metals, including white gold and silver. White gold and silver share a similar whitish-gray color, but beyond that each metal has its own unique characteristics. Knowing the differences of each metal before you purchase a ring helps ensure you get a piece of jewelry that meets your needs.

Color
The only real characteristic shared by silver and white gold is color. Although silver is usually a darker gray than white gold, the difference in color is minimal.
According to Gillett Jewellers, white gold is the second-most popular color of gold next to yellow gold. Different mixes of metal alloys, such as silver and palladium, give white gold its color.

Quality
Silver isn't as strong as gold. It's considered a soft metal. White gold is harder. It contains a certain amount of pure gold measured in carats. Gold of the same carat weight is the same quality regardless of its color.

Use
White gold is a more versatile metal for rings than silver. White gold is suitable for long-term, everyday wear and special occasions. It's an appropriate choice of metals for engagement and wedding rings. Gillett Jewellers doesn't recommend using silver for engagement and/or wedding rings as silver doesn't have the necessary qualities to stand the test of time. Silver rings are best when worn as an accent piece for a special occasion.

Care
Silver oxidizes over time, changing from silver to black. The ring needs to be cleaned with a cleaner made for silver to restore it to its original color. White gold maintains its color with little care. However, if white gold is coated with rhodium to make it whiter, then it needs to be re-plated every year or so to preserve its original color.

Cost
White gold is a superior metal compared to silver. A price difference is notable when evaluating similarly designed rings of these metals as white gold costs more than silver.

The cost of white gold rings varies depending on the percentage of pure gold it contains. The more it contains and the higher the carats, the more expensive it is. White gold also costs more than yellow gold.

The object of the game is to be the player who scores the most runs in a game. Write the numbers one through nine in ascending order on the scoreboard. Players' names are written in a batting order across the top. In batting order, each player throws the darts. For the first inning, each player must aim at the number one on the dartboard. In the second inning, each player must try to hit the number two and so on to the number nine.

Platinum and palladium are both rare elements. Palladium is a member of the platinum group of metals. Both metals have become increasingly popular in the design of engagement and wedding rings as well as other precious jewelry. Palladium shares some physical characteristics with the more expensive platinum. As such, palladium has become an increasingly popular yet more affordable choice of material for rings.

Platinum: Purity and Perfection
Platinum is appreciated by jewelers and jewelry collectors for its pure quality. Platinum does not need to be blended in an alloy with other metals to create jewelry. Its purity makes platinum hypoallergenic. Its natural white color does not reflect a casting color onto diamonds which makes it ideal for engagement ring settings with diamonds. In addition, the natural white color is flattering to a variety of skin tones. Platinum is pliable and can be worked into very intricate designs.

Platinum's Durability
The dense quality of platinum makes the element durable. Rings fashioned from platinum retain their shape and do not tarnish or change color. Additionally, its durability makes platinum ideal for holding a ring's stone in its setting. Platinum does not wear away like other metals which better secures a stone over a period of time. If a platinum ring is scratched, a jeweler can simply buff out the imperfection.

Palladium in Ring Design
Palladium has always been used for more technical applications, such as an engine's catalytic converter. Innovations made palladium more receptive to casting, a technique jewelers utilize to fashion jewelry. Because palladium can now be part of an alloy known as 950 palladium, it is better suited for casting to make rings or other small jewelry.
