Taking Care of Your Pearl Jewelry May 25, 2016 11:38
Shout out to our favorite Californian, Elizabeth, for suggesting we put more "How to take care of your jewelry" information up here. Your wish is our command!
Good rule of thumb for pearl jewelry - especially necklaces, earrings, and bracelets: "Last On and First Off."
The nacre of the pearl is the outside part of the pearl we see and love. It is what gives the luster to pearls and provides the depth of color - think of the term pearlescence. Well, you want to put your pearls on AFTER you put on any make-up, hair treatment, and even perfume. That kind of material can build up on the pearls and a) ruin the luster or b) in extreme cases even damage the nacre by eating away at it.
At the end of the day, you want to remove your pearls BEFORE you start your ablutions for the same reasons. You don't want soap or some other cleaning product that may be harsh to come into contact with your pearls.
We often tell people to do the dishes with their wedding rings on - the hot soapy water disolves the oily residue that makes diamonds lose their sparkle.
If you have a pearl ring - NEVER do the dishes with it on. They way the vast majority of pearls are attached to rings (like the one above), and many earrings and pendants for that matter, is when the pearl is half-drilled and then attached to a post using expoxy. Even the best epoxy will loosen after exposure to water.
I cannot tell you the number of pearl rings I have seen over the years where there is nothing left of pearl's nacre. The seed pearl is still on the ring, but the good part with the luster and shine has been eaten completely away.
So - please keep ALL of your pearl jewelry our of water - even showers or baths. And because of chlorine in pools and even WORSE chemicals in hot tubs - never, ever, ever ever go in a pool or hot tub with your pearl jewelry on.

Ideal Cut Diamonds Without the Huge Price Tag At Chimera Design December 09, 2015 15:00
Did you ever notice how some diamonds sparkle a whole lot more than others? Well, it could be because of the way they were cut. A round diamond cut deeply causes the light to go out of the bottom - we call extreme cases of this Nail Heads. If the cutter shapes it too shallow - then the diamond can appear lifeless - we call them Fish Eyes.
A diamond cut to ideal proportions will return light like nothing else. No other gem can take light in and shoot it back at you like a diamond.
A couple of years ago we met Michael. He is a diamond cutter from New Jersey and is a master of his craft. When he stopped in the shop to show us what he could do, we bought one of his diamonds on the spot (Cliff never does that!). Since then we have introduced couples to his sparkle-fest diamonds. Laurie was so impressed, she wanted two of them for earrings!
There is one company that has been marketing ideal cut diamonds by showing customers the hearts and arrows visible in their diamonds using a viewing device. Te result is the heart shape patterns (above left) seen from the bottom of the diamond and the arrow patters (above right) seen from the top down.
The diamonds Michael cuts are done so well, you do not even need a special viewing device to see the arrow patterns! The ring above is set with a .50 ct VS2 I diamond Michael cut and the one below features an .81 ct from Michael.

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.
NATURAL COLORED DIAMONDS
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.
