Description: Your browser does not support JavaScript. To view this page, enable JavaScript if it is disabled or upgrade your browser. The Oregon sunstone is a 9 X 6 X 4 mm faceted pear set in a four prong sterling silver basket setting. The gem is 100% natural, genuine and has had no treatments. Oregon sunstones should never be dyed or treated in anyway. This is uncommon in the world of gemstones today, as most gems are treated is some way before they reach the retail market. If the Oregon sunstone is treated or heated, the gem is suspect as being an imitation. Studies have proven that the claim of natural sunstones supposedly found in the Congo called Mongolian sunstone are really doped labradorite. This sunstone weighs 1.20 carats. Its colour is a transparent medium peach. The pendant includes an 18" .925 sterling silver rolo chain, 1 mm thick with a lobster claw clasp. Rolo chains feature twisted links that are created from flat or half-round wire. The shape of the links may be round or oval. Oregon sunstone are in the feldspar group of minerals, one of the most common on the planet. However; Oregon's unique copper-bearing plagioclase feldspar, is found nowhere else in the world. At a hardness of 6.5 - 7.2 on Mohs' scale, it is comparable to gemstones like tanzanite and peridot. It is cautioned as a ring stone unless properly designed for this purpose. Schiller describes the glimmering flash or shimmer which appears in some stones, this is due to metallic copper inclusions which are unique to Oregon sunstone. It can be lightly sprinkled throughout the gem or be deposited very densely to the point of affecting brilliance. Only in the past 15 years has Oregon sunstone grown in popularity as a gem. The colours of Oregon sunstone are difficult to compare to traditional sunstone because so few gems display such a wide variety of naturally occurring colours.

It should be noted that natural plagioclase feldspar deposits are found in India, Canada, Madagascar, Norway, Russia (Siberia), Tanzania and the United States. It is the consensus in gemological societies that Oregon deposits produce the best premier gem-quality sunstone in the world. The current Oregon sunstone mines are dispersed in only a few different locations in the southern part of Oregon, often referred by locals as the "Oregon Outback". Sunstone from Oregon is formed in molten lava and is discharged close to the surface with the help of a volcano. The lava wears away or is broken and gradually makes its way to the surface to expose the gem.The photos have been enlarged to show detail. I have pictured the necklace next to a dime for size reference. I have LED lighting in the photography. Gemstones are creatures of light, the depth of colour will vary with the light source. I will be including the gemstone description with the necklace. This should be kept with the necklace for future reference.I use high quality metals in the jewelry settings. I do not use silver plated settings or chains. The settings & chains are .925 sterling silver and is the standard for silver. It is called .925 because it is an alloy that is 925 parts out of a thousand silver. It is allowed for the other 75 parts to be other metals (usually copper) to enhance the strength, because pure silver is very soft and not structurally strong enough for many jewelry applications. Other "silver settings" come with different elements in their composition. German/Nickel Silver, which is a alloy consisting of copper, zinc and nickel, contains no silver. Many people have allergic reactions to nickel. Other settings may be called Mexican Silver, Indian Silver, Montana Silver, Pewter, Tin, Pot or Base Metal or simply silver. The content of these are less clear and do not guarantee the quantity or silver content. .925 is the best form of silver. It is durable and has a high sheen. Sterling Silver is considered a precious metal.Inside the gift box, the jewelry is placed inside an envelope with a 1" X 1" anti-tarnish tab. The tab provides protection from tarnish for up to 12 months. It does not leave deposits on items it protects. It is non-toxic, non-abrasive, and will not scratch metal or gemstones. Place strips in jewelry cases, storage bags or boxes. Each tab protects up to 30 cubic inches of container space. 11/2020 UPDATE: Mongolian sunstone sold as the equal of Oregon sunstone was first suspected to be man made in 2008. This material was first claimed to be from the Congo and then later claimed to be from Mongolia. Gemologist and geologists from different countries and laboratories have found the following facts based on their evidence: 1) The Mongolian sunstone is really an artificially copper-infused treated pale yellow feldspar; 2) The vast majority of the pale yellow feldspar starter material sold as Mongolian sunstone came from the autonomous region in Inner Mongolia, China, not from Mexican labradorite; 3) Natural red-green andesine with copper platelets does exist and has been found in the lower Yu Lin Gu Valley, Tibet; 4) A small quantity of the Tibetan material is collected and sold by the locals. The Tibetan stone is generally unattainable for the average consumer as it takes traveling to the source. If a consumer can obtain the Tibetan andesine, the only remaining question is how to properly insure you have the natural Tibetan stone and not the artificially treated Mongolian stone. It is still massive fraud to secretly sell treated feldspar to consumers as natural copper bearing andesine. Consumers can still have 100% confidence in Oregon sunstone as natural and untreated with its abundant copper schiller. After all, that is what they tried to replicate.I guarantee my jewelry 100%.
