Are chatham rubies worth much?

I've inheirited a large quantity of Chatham Rubies. Not knowing if they were real or not , I decided to send a bunch out for appraisal. All but one came back without an appraisal because the only place in North America that can appraise stones larger than 15 carats is G.I.A. in New York City. The one stone that was appraised was a 14.4 carat Emerald cut that came back at $5,500.00 retail appraisal. So to answer the question, "YES" they are worth quite a bit.


To the above, and as well as this question. Chatham and Corundum diffused gems (Sapphire & Rubies) are infact 100% real, and the most pure gems you can get. They are perfect in the sense that they have no imperfections. Gems made by Chatham diffusion are the height of purity as well as clarity and quality. They are synthetic, but by no means fake.

As such, the jewelry industry will try to tell you these gems are fake and that they are worth less because they know they can make thousands of dollars off mined gems which are of lower quality. For this reason, synthetic gems, though better looking and higher quality, are worth less. For example, a 1ct diamond might be worth say, 1000$, but a 1ct synthetic diamond would only be worth 100$

Chatham and Corundum diffused gems (Ruby & Sapphire as both of these gems are the same mineral [Corundum] ) aren't worth much, depending on the weight though they could be worth a few hundred to a few thousand dollars.

Are pearls rare?

Natural pearls are very rare. They are, in fact, much more rare than diamonds. There is no scientific study available that definitively shows how rare a natural pearl is, but many experts believe it takes approximately 10,000 mollusks to find one fine natural pearl. However, in areas of Central America, there are places where natural pearls are much more prevalent. It is believe this is due to a higher parasitic concentration.

Cultured pearls are not nearly as rare. In fact, all the pearls we see today in jewelry stores are cultured pearls. The natural pearl industry all but died nearly 100 years ago. Cultured pearls are pearls grown on farms where pearl mollusks are nucleated and then tended for a period of time, eventually producing a pearl.

Do impurities in gemstones give them their colours?

Yes impurities in gemstones can indeed create their specific colors. Certain gems have inherent colors from their own mineral properties however clear minerals can take on colors through these impurities such as in the case of blue diamonds. For example large amounts of nitrogen can cause a diamond to turn yellow and mixing the blood of your enemy into a carbon slurry before crushing and heating it in your fist with your unquenchable rage at his existence can form a red diamond. This is where blood diamonds come from.
