A Quick Education About Colored Diamonds August 21, 2015 17:09

Colored Diamonds From The Laboratory

We have a line of colored diamond jewelry at Chimera. 

The colored diamonds we sell (usually) are natural, white diamonds that have been changed into colored diamonds. There are three methods that can be used singly or in combination with each other depending on the color desired.

Electron Irradiation - a pulsed beam of electrons that will induce color into the diamonds is fired at them. The light absorbing pattern is changed and so is the color. Used alone, this process gives diamonds a blue or greenish blue color. 

Annealment - To expand the range of colors, super heating them in an oxygen-free environment in temperatures 900 degrees and higher allows us to get other shades of color. The atomic structure of the diamonds rearrange, and a new palate of colors is possible.

High Pressure High Temperature (Hpht) - The HPHT process recreates the heat and pressure that creates diamonds initially in the Earth. Sophisticated machinery is programmed to accent conditions to get yellows, oranges, and greens. 

There is a fourth method consisting of coating the diamond, which is used to create a truly pink color. The coating is done at the pavilion - the lower part of the diamond. This allows the color to shine through the entire diamond.

The first three treatments are more stable than the fourth. Diamonds that have been irradiated and/or annealed will not fade over time and they will wear like a normal diamond. The only caveat is that when being worked on by a jeweler, they need to be careful NOT to expose the diamond to heat in excess of 900 degrees which could occur when sizing a ring.

The HPHT method requires no caution of any kind.

The technology creating colored diamonds has moved forward tremendously in the last decade. When we first opened in 2002, treating diamonds was reserved for those very low on the clarity scale (I1 to I3) because the science was very in-exact as to the results. Sometimes they came out looking terrible. Blue ones could be all over the color spectrum and it was hard to create diamonds that were a good color match even when they were treated together. 

Fast forward to the present day, and companies like Lotus Color can provide colored diamonds with better clarity (SI1-2) and with wonderful consistency. This makes it much easier to design and build colored diamond jewelry that is affordable and beautiful.



They exist and they are extremely rare and costly. A 9.75 ct natural blue diamond (above) was auctioned in 2014 for 32.6 million dollars. Pink diamonds are found in Australia in very limited quantities and typically command prices in excess of what most of us can handle. 

Typically a yellowish tint causes the price/value of a diamond to go down. That is true until the saturation of the yellow color reaches what GIA terms "Fancy" and then the price jumps up like a ROCKET! 

Conclusion - creating colored diamonds in the lab is a wonderful way to make the long lasting beauty of colored diamond jewelry something that regular people can afford and appreciate. We are excited to offer colored diamond jewelry in our store and to you online.

You Can Create Jewelry Online at The Chimera Showcase August 12, 2015 10:50

We are very excited about our new online Chimera Showcase - you can design jewelry, insert various size, color, and shape gemstones and diamonds into YOUR choice of metals. Not only will you get instant visualization of your creation, but you will also have an estimated price that will change when you make changes in the piece, (e.g. from 10kt to 14kt gold or by substituting one gem for another).
This is some of the most fun you can have with jewelry online - we guarantee it.
Deb came in with a couple of diamonds and the desire to make a ring with them that would also incorporate her birthstone - Emerald. We went to the Chimera Showcase and looked around. She loved the contemporary look of the half bezel settings in this ring. We tried several shapes for the center lab-created emerald (Princess cut above), and she settled on a round one that would be slightly larger than her two diamonds - the diamonds are 5mm and the emerald is 6mm.
Once Deb settled on a design, we secured a price and placed the order. Her custom-designed ring was delivered about 10 days later for her to inspect before we set the gems. One great aspect - the jewelry from our Showcase is ALL made in the US - by our friends at Stuller in Louisiana. 
To give you an idea of how accurate the computer images are, here is a picture of the finished ring with the 6mm center and Deb's diamonds. We LOVE technology!
One more thing about our Showcase - Don't worry, we are not trying to lure you into designing a $10,000 piece and then buying it! You CANNOT purchase your design directly from the website.
What you can do is save the final design(s) you like and then Cliff will be notified and contact you with an accurate price quote - how cool is that? 
Please follow this link to our Online Chimera Showcase and have some fun designing rings, pendants, or earrings with the easy-to-use software. If you end up with a design you really love, save it and Cliff will contact you with a quote. Easy peasy!

Learn About Clarity Enhanced Diamonds August 7, 2015 17:06

Cliff has been selling diamonds for over 18 years now. He earned his Diamonds Graduate certification from GIA in 1998. Over the course of his career, he has sold clarity enhanced (CE) diamonds to a lot of people.
So what does "Clarity Enhanced" (CE) mean?

The imperfections in diamonds are called "inclusions" if they are inside the diamond and "blemishes" if they are on the outside. There is one particular type of inclusion that can be "repaired" using the clarity enhancement process: a feather. A feather is an inclusion that reaches the surface of the diamond. This picture shows a nice close up of a feather:

In the clarity enhancement process, a clear glass-like filler is put into the feather at an extremely high temperature and under very high pressure. (The industry guards the specifics, as you might imagine.)

Anyway, the material has the same reflective properties as a diamond, so you do not notice it unless you examine the diamond under magnification. It is also very noteworthy that the lab at GIA has weighed clarity enhanced diamonds before and after the treatment, and since the amount of material used is so minute, it adds no weight to the diamond. Very important since diamonds are sold by weight. GIA does NOT certify CE diamonds, but other labs do.

The CE process is NOT a miracle worker - you cannot take a I2 clarity diamond and turn it into a VS clarity stunner. Most times a diamond will move up one or possibly two notches on the clarity scale. That being said, what the CE translates to in terms of your pocketbook is that you can save about 30% by purchasing a CE gem.

Here are a couple of examples of the difference the CE process can make:

 The top example has multiple feathers while the lower one has a very noticeable feather almost dead center on the diamond. The CE process renders them pretty much invisible. We say "pretty much" invisible because the process can be detected using magnification. Turning the CE diamond while examining it will produce a "flash" of color - most times a purple or orange or combination.

Here is an excellent photo of filled feathers demonstrating the purplish flash -

 Any CE diamond we sell has a Lifetime Warranty on the process.

 CE diamonds are not for everyone - but our attitude is that they are just another enhancement. Shoot, if you take a look at a diamond crystal the way they come out of the ground, you might not be impressed. You would probably walk right by one if you didn't know what you were looking for. It could be argued that cutting and polishing the diamond is a "clarity enhancement".
Here is a totally natural diamond crystal before cutting and polishing:
The ring below is an example of jewelry we made using clarity enhanced diamonds. The person who owned this ring saved about $2,000 by choosing a CE diamond. It was cut to ideal proportions and sparkles to beat the band!


One last example: Two CE diamonds put into halo-style earrings. They weigh a total of 2.13 ctw and are accented by .22 ctw of diamonds. All in all, a gorgeous pair of earrings at a wonderful price, thanks to the clarity enhancement process. By using CE diamonds, this couple saved almost $3,000.00.


 Hopefully you learned a little bit about CE diamonds. If you should have any questions, feel free to email or call Cliff - he loves to talk about diamonds.




Should I Wear My Jewelry In A Pool or Hot Tub? July 31, 2015 18:18 3 Comments

Information about the care, cleaning, and manufacture of fine jewelry.

Swimming pools, hot tubs and your jewelry.

The short answer to the question above is: NO to the pool and NO-NO-DEFINITELY NOT to the hot tub.

A few words of caution about SWIMMING POOLS and HOT TUBS. We do not recommend that any fine jewelry be worn in public swimming pools or hot tubs. Chlorine is a corrosive chemical - it won't do any harm to diamonds, rubies, sapphires, and some other gemstones, but it is not good for your white or yellow gold to say nothing of sterling silver.

Chlorine can also discolor and/or prematurely wear out your watch - even watches rated to be underwater. (See our blog post on that subject: Watch Ratings)



Hot tubs are waaay worse than pools because in addition to harsh chemicals, you have the addition of high temperatures AND the pressure of the water coming out of the jets. We do not recommend that any jewelry or watches be worn in hot tubs. Even watches that are rated to go under water to some degree can be infiltrated by the water coming out of the jets.

Hot tubs are great for humans - they are a TERRIBLE environment for your jewelry and watches. Take the little bit of extra time to remove your jewelry and watches BEFORE you get in.

Kevin asked if it is safe to wear his titanium ring in a hot tub on a daily basis. My answer to that would be.....maybe. If the titanium has any kind of enameling or stone of any kind in it, then NO. If it is a plain band, there will probably NOT be a problem - but if it has any type of a finish on it, you might find that a daily dunking in the chemicals would change the appearance of even a titanium ring. Best bet - take it off - take it ALL off!!

I would make the same recommendation for those folks with tungsten or tungsten carbide rings. We sell them and I wear them and I would take mine off before spending time in a hot tub. Heat and chemicals wreck havoc!

What Do The Ratings on Watches REALLY Mean For Going In The Water July 31, 2015 18:08


What does water resistant really mean?

Answer: Two-thirds of all watches are designated water resistant.
(Government guidelines prohibit manufacturers from labeling their watches "waterproof.") While you might think a water resistant rating such as "water tested to 50 meters" would mean that someone could safely wear a watch, say, scuba diving, it's really not that simple.

Why? Because testing is done in still water, with a stationary watch. Movement greatly increases pressure, so it's necessary to translate the water resistance ratings into practical guidelines.

The following scenario happens in our store almost every Spring, when people are returning from vacation. A guy comes in with a watch rated for 50 feet that is full of water - heck, he was only swimming in 8 feet of water!!

From the least to the most water resistant, the ratings are as follows:

  • Water Resistant  - These watches have withstood testing to depths of 24 to 30 meters (100 feet) and will tolerate splashes of water or rain, but should not be worn while bathing, showering, washing dishes, swimming or diving. Watches with this designation will have the words Water Resistant engraved on the case back.
  • Water tested to 50 meters (165 feet) - Okay for showering, bathing, dish washing and swimming in shallow water. Not while snorkeling or scuba diving. The designation engraved on the case back will be "Water Resistant 5 BAR" (BAR is a European equivalent of the international measurement ATM, or "atmospheres."  To calculate the water-tested depth in meters, multiply the BAR number by 10.)
  • Water tested to 100 meters (330 feet) - These watches are suitable for swimming and snorkeling, but not scuba diving. The case back designation will read "Water Resistant 10 BAR".
  • Water-tested to 150 meters (500 feet) - These watches can be worn for general water sports, including snorkeling. The case back designation is Water Resistant 15 BAR.
  • Water tested to 200 meters (660  feet) - These watches can be worn for general water sports, including snorkeling and skin diving (without scuba gear). The case back designation is Water Resistant 20 BAR.
  • Diver's 150 meters (500 feet) - Meets ISO standards and is suitable for scuba diving.
  • Diver's 200 meters (660 feet) - Diver's watches with the Water Resistant 20 BAR designation on the case back are our most water-resistant models.

The Importance of Cleaning and Maintaining Your Jewelry July 31, 2015 17:49

Information about the care, cleaning, and manufacture of fine jewelry.

The importance of jewelry maintenance.

Jewelry Maintenance - this is a serious subject. For most people, a diamond ring represents the biggest jewelry investment they have. Most diamond rings - engagement, wedding, or anniversary rings - are worn 24/7/365. Just like anything else - your jewelry needs to be maintained - especially a ring on your finger.

When your ring is new - the diamond(s) is secured by prongs and tips.


The tips on the prongs come up over the edge of the diamond and help to hold it secure in the mounting. Over the years you put your hand (ring) in and out of your pockets, in and out of gloves, and generally wear the heck out of it. That is a good thing - but you should have your rings inspected at LEAST once a year. A competent jeweler can look at the condition of your ring and know if your diamond is secure in the mounting.


Look at the picture of the new ring - then compare the tips on it with the other examples. (These are actual rings that have come in our shop.) Tips and prongs can be replaced - for much less than the cost of a diamond! Most ladies will get 8-12 years wear - but we know ladies who wear tips down in 3 years and sometimes even quicker.




We do not charge for inspection, nor do most jewelry stores. Let a pro take a look for you at least once or twice a year. It can save you big money to say nothing of the sentimental value.


This is a new ring. Notice the tips come up

over the edge of the diamond, holding it in place.


You can see how the tips have worn away,

this diamond is ready to fall out.


Another example. This diamond has a 6

prong head, but 3 of the 6 are GONE and

the other 3 are very thin. DANGER!!!



One last example - see how the end of this diamond is exposed and two of the other four prongs are essentially gone.
