MARKET NEWS:
At the market there are many rubies. 10% are artificial 88% are heat treated and filled, 2% are real and a few of them are clean and a few of the few are cut so they create fire rather than size. Rarely a fine example above 1.5 carat. Colors can range from pinkish to dark purplish red. The pick is between a cadmium red (African) or a magenta (Asian) with the Burmese and Vietnamese on top. Pakistan and India buy most of the poor African rubies in large lots to sell to brides in the sub continent. These are mostly heat treated and filled with flux or ground corundum. Thailand is the main producer of such low grade rubies. Purchasing ruby is difficult as prices can range upwards from a few dollars to tens of thousands. Sometimes in the 88% a few might be discovered that are heated but unfilled. These are worth a reasonable ($100+ per carat} price if well cut with good fire and only natural inclusions.

MARKET NEWS:
One of the most diverse and difficult gems to purchase as many colors, shapes, sizes and origins confuse the issue. Also a myriad of treatments, enhancements and artificial gems flood the market with gems that are difficult to separate from the naturally mined. Kashmir, Sri Lanka, Thailand, and Burmese are all shades of the blue sapphire offered. There are also the rare color change varieties. If you really want a blue gem for its fire then tanzanite is great although a little brittle. You can see why some buyers specialize in sapphire for only a few can pick out the good ones. The price of certification of a sapphire is high due to the difficulty of the task so the average buyer is really at a loss. The market can also offer blue sapphire that is artifically grown on a natural gem to make it larger. I like to search for color change sapphire or buy small blue sapphire for jewelry. Pink and yellow sapphire are usually treated for color. 90% of the blue in the market is heated for color and although green is usually natural it is also common and dull. White sapphire is also good as a jewelry support gem if diamonds are overly expensive.
