However, opaque gemstones or organic gemstones are affected by water or any chemical substance. These are usually porous and will allow the water or chemical to flow inside the gemstone. Once inside they can either build up inside, make the stone loose its color or even cause it to crack. Therefore these kind of gemstones should be kept away direct contact with any kind of chemical in sprays, cosmetics and even from water.

There are advanced methods using certain technology to help clean gemstones. Expert jewelers and dealers are well-versed with all these methods and know how to clean each specific kind of gemstone. Therefore it is advised that you do not do the cleaning yourself and rather, have it done by someone who knows more about how to deal with them. If you can afford to buy a gemstone, why not spend a little more money on keeping them safe and clean?

Gemstones are hard materials. In contact with some other gemstone or the metals which contain them such as gold, they can crack each other or the metal. Therefore care must be taken with jewelry how it is kept and handled. Jewelry is expensive and valuable, especially those with precious gemstones in them, therefore they should be treated with care.

The first of these, carat, refers to the weight and mass of the stone. A carat is approximately equal to one-fifth of a gram. Color is just that. Diamonds for sale come in a wide variety of colors that range from ice-clear to black depending on what other elements are present; pink and blue diamonds can be especially valuable. Clarity is determined by any “flaws” – interior cottony patches that are visible from the outside. Diamonds for sale are assigned a fair market value by the process of appraisal. It is very important when considering the purchase of diamond jewelry for investment purposes. Additionally, if you plan to insure pieces such as diamond earrings or even diamond wedding bands, you will be required to provide such an appraisal report for your carrier.

But these concerns can be addressed by being a smart eBay shopper. After all, when you buy on eBay, the savings can be huge and you can find really unique jewelry items!

Before bidding on any diamond or precious gem (such as emerald, ruby or sapphire), make sure you understand how value is determined for that particular stone. There’s no excuse for not being an educated shopper. If eBay sellers don’t address these characteristics in their auction listings, click on the “Ask seller a question” link and get answers before you bid!

Determining Value

For diamonds, that means evaluating the four Cs: clarity, color, carat and cut.

Clarity is the term used to describe the size and number of inclusions (minute traces of non-crystallized carbon) in a diamond. Most are invisible to the naked eye; the larger and more numerous the inclusions are, the less valuable the diamond.

Diamond color grades start at D and go up through the alphabet. Truly colorless stones, graded D, are extremely rare and very valuable. The closer a diamond is to being colorless, the rarer and more valuable it is and the more it will shine.

Carat is how the weight of a diamond is measured. The larger the diamond (the rarer) the more expensive per carat it will be. Carat refers to weight, not size or diameter, although diamonds of identical weight can look larger or smaller depending on the cut.

The cut of a diamond determines how it refracts and reflects the light; a well-cut diamond will seem brighter and properly cut.

To find the best diamond that fits within your price range it essentially comes down to a compromise between the 4Cs and your consideration of which factors are most important to you.

There is a “fifth” C, or Certificate. A certificate diamond has a “report card” that grades the four traits mentioned above, including listing specific items about that particular diamond that are unique to it. A certificate goes a long way towards establishing the trustworthiness of an online diamond seller.

Gemstones such as rubies, emeralds, and sapphires usually undergo treatments to enhance color and fill cracks. The jewelry industry considers treatment of these three gemstones standard practice. Such treatments include oil and resin treatments; heat treatment, and chemical or “diffusion treatment.”

Most eBay sellers will provide details about any treatment applied to their gemstones. If they don’t, request the details before bidding on the item.

As you can see, what to look for specifically depends on the type of stone you’re looking for – and it’s not possible to explain all that in one article – but this is the type of info to look for, especially if you intend to spend very much money.

Finding Deals

Finding a deal on a diamond or expensive gemstone requires some counter-intuitive thinking. You’re looking for listings that won’t attract a lot of bids. Lots of bids mean lots of competitors and a higher final price.

How to find these less-popular listings? Try searching for misspelled words (e.g. “dimond” instead of “diamond”). Look for items that end at odd times (say, 3:00 AM), when most bidders are in bed. And listings without pictures don’t attract as much attention, either – you may find a real “gem” by taking the time to look.

Who to Trust and What to Look For

As with any eBay auction, the seller’s rating is extremely important. This is an aggregate score based on how other customers have rated them. Look for sellers with a very high rating (I suggest over 98%) and look at the customer feedback they’ve gotten. Sellers with lots of happy customers are pretty reliable.

Second, check for any return or exchange policies. A reputable seller wants repeat business and repeat business means happy customers who leave positive ratings. Getting that means they need to bend over backwards on returns and exchanges to avoid getting negative ratings on eBay’s services.

Third, see if the seller has an “About Me” page (look for the word me in blue and red letters in the “Meet the Seller” section) or an eBay store (there will be a link that says “Visit seller’s store”) or an “About Me” page.

Many times, the store or About Me page includes further information on the eBay seller. Often you’ll find addresses or phone numbers of a physical brick-and-mortar store, which can be very reassuring. Don’t hesitate to call and ask questions!

Protecting Yourself When Paying

Figure delivery costs into your final price – and look for suspiciously high shipping costs (a sign of an unscrupulous seller). If you spend a lot of money, make sure the seller will insure the item when it ships.

When paying, use a credit card – preferably through PayPal. PayPal allows you to pay securely with your credit card and it’s owned by eBay, which makes it the preferred payment mechanism for eBay sales. And there’s additional protection when buying through PayPal, up to $1,000 in value.

Following the steps above should help ensure a hassle-free diamond or gemstone buying experience on eBay. Good luck!
