Wedding Bands. Emerald Jewelry. Blue Sapphires. Pink Sapphires. Yellow Sapphires. Montana is also the claim to a few other localities: Salesville, Gallatin Co. Other famous occurrences are at Hastings Co. Large deposits of Emery were worked near Peekskill, Westchester Co. Rubies can be found in the U. A few scattered finds were reported in Sparta and Ogdensburg, Sussex Co. The production of gem-quality sapphires in the United States is not new or recent. In , the first U.
Furthermore, corundum crystals, from which star sapphires have been cut, are found in Beaverhead and Madison Counties. But until very recently, with the exception of Yogo Gulch material, the commercial gemstone industry has had limited interest in U. In , the mine was damaged so badly by rain that it could not economically recover. Other attempts have been made to commercially mine the deposit, but to date, all of these attempts have ended in economic failure.
Yogo's are unique among the world's sapphires. They lack the color zoning so prevalent in other sapphires, their uniform "corn-flower blue" color is natural not the result of heat-treating , and their clarity is uniformly high. These features rank them among the world's finest sapphires. Unfortunately, the rough is both small and flat, wafer-like in shape. The majority of the crystals or pieces of crystals recovered are too small to be cut, most are less than 1 carat and finds of over 2 carats are rare.
Reportedly, the largest crystal was a 19 carat stone found in that was cut into an 8-carat stone. The size of the cut stones greatly restrict the market for Yogo's, they are beautiful, small, very expensive sapphires.
Currently, Yogo sapphires are produced from three sources: Rancor lnc. The first two producers market only cut stones and finished goods and the third is comprised essentially of hobbyists. Historically, the amount of sapphires produced from the Missouri River and Rock Creek areas greatly exceeded that from Yogo Gulch. This relationship is rapidly changing. The combination of large volume commercial operations on the Missouri River, and to some extent Rock Creek, plus the advent of successful heat-treating techniques for the material has greatly enhanced the acceptance of these sapphires by the gemstone industry.
This enhanced acceptance has resulted in a significant increase in the market for and value of U. The sapphires from the Missouri River gravels in Lewis and Clark County are a mixture of rough and pitted crystals showing well defined faces and completely rounded and smooth-surface highly stream worn pebbles.
The majority of the material is pale blue or blue-green, with deep blue stones quite rare. Stones also are found in pastel blue, green, pink, pale red, purple, yellow, and orange. Most of the stones recovered are less than 6. Material greater than Not all of these may be active in any one year.
It is the author's understanding that one operation, currently inactive, a self-propelled floating inch suction dredge is for sale. The mines operate from about the last week of May through the first week of September. The Rock Creek sapphires are very similar to the sapphires from the Missouri River but differ in the general shape of the crystals. The stones are basically crude hexagonal plates about the same dimension in width and height, with a much higher percentage of the material being well rounded water worn pebbles.
There appears to be more of the larger sized greater than Additionally, it is reported that the Rock Creek material has a greater percentage of stones that can be heat-treated for color enhancement. During the past several years, there has been only a single producer on Rock Creek. The producer operated both a commercial recovery plant and a fee recovery area. The fee recovery area sold buckets of gravel for washing and also offered, for a predetermined fixed fee, the output of one day's operation of the commercial wash plant.
There is work underway which would result in a second, much larger producer, opening an operation on another deposit in the area.
If things go as planned, the new operation on Rock Creek would be the largest sapphire producer in Montana. There are a number of locations between Dillon in Beaverhead County and Ennis in Madison County that produce lavender, grayish-lavender, bluish-gray, and gray hexagonal sapphire crystals that, when cut, produce stones that contain four- or six-ray stars.
At least one producer from the Dillon area is currently advertising the availability of this type of material. The remainder of the sapphire deposits in Montana appear to be operated by individual hobbyists.
North Carolina. Today a number of dig-for-fee operations are located in the Cowee Valley. Each year many people pay to dig or purchase buckets of gravel to wash in hopes of finding a sapphire, garnets, and other gem materials.
Many of the dig-for-fee operations have enriched the gravels with gem materials from other locations. Every year articles appear in magazines and newspapers about large and valuable sapphires found at one or more of the mines in Cowee Valley.
No doubt large corundum crystals and pieces of corundum are found each year. By the same token, valuable sapphires may be found, but the number of large valuable gemstones are far less than reported, and the values are generally not as great as reported. During the period when the area was commercially mined, gem material was found that would cut fine quality 3- to 4-carat stones, but the amount of quality gem material available has greatly declined. It is doubtful that North Carolina will ever again boast of commercial sapphire production, or that the commercial gemstone industry will seriously consider the State's saphire deposits.

At the end of the day, color is always a personal preference. Most of the green sapphires in our inventory come from Montana, subsequently, one of the only states in the US that can produce sapphires. A sapphire with no inclusions or obvious marks is often viewed with suspicion; it may be a synthetic stone or even a glass imitation.
What are inclusions? Inclusions are a natural consequence of crystal growth and even the best stones are not expected to be totally inclusion free. For surface blemishes, like scratches or chips, it is important you inspect the stone carefully yourself. If the cut is poor it will look dull and lifeless. As a result, well-cut greens are easier to find.
A good cut is especially crucial if the stone color is light. Darker stones can look lively and dramatic, even if the cut is not perfect.
Although not rare, it is unusual to find a green sapphire over two carats in weight. And the larger you go the higher the price. A five carat sapphire can cost five times more per carat than the same quality one carat stone. Most of our green sapphires are between one and two carats in weight, although we do have a few larger stones too. It is very important to find the right setting style and ring metal to make the best of your chosen sapphire. If you are creating your own personal ring design our advice would be to pick your stone first and then test it against different ring metals.
At the Natural Sapphire Company, you can view high quality images of what your chosen stone and setting would look like together.
An unrivaled service. In saying this, green sapphires tend to suit the more silvery metals platinum, palladium and white gold and go well with quite ornate settings. Silver itself is quite a soft metal and is susceptible to tarnish, unlike the other metals mentioned. But, beauty is in the eye of the beholder. It is what you like that counts. Emeralds tend to be more vivid green in color and command a higher price per carat than green sapphires. One of the key differences between a sapphire and an emerald is their hardness and durability.
Sapphires have a hardness rating of 9 on the Mohs scale and are used in scientific instruments and as wrist watch crystal faces. Emeralds are an 8 on the same scale which means they are reasonably durable, but liable to cracking and scratching. As emeralds are type III gemstones, it is common for even very beautiful emeralds to have a great many flaws and inclusions.
It is acceptable for mined emeralds to be oiled to improve their color and clarity, an industry standard. The process of oiling involves immersing an emerald in oil which seeps into the cracks and fissures which are commonly found in emeralds. The majority of commercial emeralds have been oil treated. Another important difference is that sapphire have trigonal crystals while crystals of emerald are hexagonal.
This means sapphires can be cut to many different shapes while emeralds are limited to more rigid-cuts. As with all gemstone purchases, insist on verified documentation; preferably independent examination reports that detail the identity of the stone. Factors such as weight, dimensions, clarity and color rating and whether there are indications of heating should all be recorded.
