Genuine Sea Glass is a term that I starting using in 1992 when By The Sea Jewelry first went online. Now used widely, it has become the standard term to indicate that sea glass is natural found glass just the way it was picked up from the beach.
We now use the term Certified Genuine Sea Glass© to distinguish ourselves from the pack. Certified Sea Glass means that we verify the glass in the most complete way possible.
Other terms include, natural sea glass, real sea glass, found sea glass, pure sea glass, true sea glass, unaltered sea glass, authentic sea glass, well,,,,,,,you get the idea.

We Certify each piece of sea glass jewelry we sell to give you the most in depth knowledge of the Origin (if known), Quality and Rarity. Each piece comes with a description of how to tell "Certified Genuine Sea Glass"©2009 Linda Jereb - from artificial craft glass.
Many people have asked "How do I tell the difference?"
Genuine Sea Glass or Certified Genuine Sea Glass© (or whatever term you use) means the glass in your jewelry is unaltered from the way it was found on the beach (not tumbled or created by any artificial means). Real natural sea glass comes from old bottles, jars and other glass items that have been discarded in the ocean and tumbled naturally by waves and sand over many years. It can take many decades for sea glass to be formed.
By The Sea Jewelry is proud to offer some of the rarest sea glass pieces available for public sale.
Genuine Sea Glass and Certified Genuine Sea Glass© (natural sea glass) has many characteristics manmade glass cannot duplicate. Below are some of the main characteristic of your natural sea gem.
1.Pores - are the main feature of real sea glass. Under a microscope, these pores resemble small "c" shaped abrasions this feature is caused by years of tumbling in the surf with the different sizes of sand, gravel and hydration from decades of exposure to the water. Some sea glass can have little pore effect if it was not in a surf environment or if it was obtained while scuba diving old dump areas on the coast. (Fake or faux sea glass seldom has uneven texture because the media used to tumble it in a commercial machine is uniform in size or the glass has been etched with chemicals leaving no pores. While faux sea glass has a certain appeal, it does not have the beauty nor value of naturally collected sea glass).
2.Frost - upon removal from the water, crystalline formations A frost can be seen on real sea glass. You can conceal the frost and magnify the color of your jewelry by rubbing a drop of oil into the surface. Frost is caused by years of exposure to water where the structure of the glass actually breaks down from salinity; hydroxide then leaches to the surface of the glass. It is NOT salt residue. Salinity or the water has a great effect on sea glass (glass from fresh water is usually call Beach Glass) and adds to the hydration process and therefore the quality of the glass. This texture in real sea glass is not achievable by artificial means.(Faux glasses can have tumbling residue but not the have the true frost of real sea glass some fake glasses are achieved by tumbling and acid etching). Frost can sometimes be lost in the jewelry making process but can be brought back by cleaning with alcohol.
3.Quality - An overall term for the remaining factors; Thickness - Shape, Color and Bubbles can be additional features. Thickness and shape - Some real sea glass can be thin but the thicker it is the older is likely to be and it's shape will sometimes have curvature (newer glass is much thinner than vintage glass and many fake sea glasses are made from colored flat rolled glass with no curve like from a real bottle or jar). Color , there are simply colors of sea glass that are no longer widely used or even manufactured today. Bubbles appear in some older sea glass pieces and are from the handmade glass process.
Remember , while not all sea glass pieces have all of the listed features, most natural sea glass pieces have several of them!
What To Look For In Fake Sea Glass
Many companies and individuals are selling tumbled or etched glass as the real thing.
Be careful when purchasing sea glass from someone who claims to sell sea or beach glass at cheap rates. Rare colors are just that, RARE, and a lot of people out there are selling manufactured glass as "SEA GLASS" or "BEACH GLASS".
Ask questions! If buying from a private seller, ask them if they personally collected the glass. Most disreputable will hedge this question in a wide variety of ways from, "I bought it at an estate auction" to "we bought it at a flea market. Believe me I have heard them all!
Cost is the best determiner. If you see a bag of blue or red sea glass for $5.99 and claiming it is real sea glass, it is not. For example - A single piece of bright aqua sea glass (unset in jewelry) recently sold for over $260. Single unset top quality red pieces can go for well over $100 in a pendant size. A pair of genuine blue earrings can sell for a much as $70 where a pair of artificial or faux sea glass will sell for around $25.
We are tireless when talking to the public about explaining the difference between the genuine and artificial sea glass.
