Precious Colored Stones: How to Buy Emeralds, Rubies and Sapphires

Precious colored stones are powerful, rare gifts. For centuries, people groups across the globe coveted colored stones. In the Roman times, Middle Ages, and ancient China, people sought out rubies, sapphires and emeralds for their healing powers or presentations of objects or feelings.

Today, jewels such as emeralds, rubies and sapphires edify both the giver and recipient. You can harness desires of the ages and learn how to buy rare emeralds, sapphires, rubies and diamonds. Precious colored stones offer brilliant shine and premium color not available in options like gold. Whether you’re at a charity gala, formal party or wedding, establish your influence with shimmering bracelets, earrings and necklaces.


Choosing colored stones are slightly different than diamond rings in Houston. For example, learning how to buy an emerald involves color. The brilliant colors of precious gemstones contain three factors: hue, tone and saturation.
-Hue. Purity in color is the most critical factor when choosing a colored stone. Very pure colors will have few and minor hues from other colors. For example, a blue sapphire should be as pure as possible, with very few other colors tarnishing its brilliance (such as purple or green).
-Tone. Tone is an industry term used to describe the color depth of a gemstone. Like the colors in a rainbow, hue can range from no color to black. The highest of value tones are saturated, or those in the darker ranges, not very light hues.
-Saturation. The final factor determining the color of a ruby, emerald or sapphire, saturation refers to purity of color. Essentially, the stone should have no gray or brown tones in it to qualify as a strong or vivid saturation.


When you work with a reputable jeweler in Houston to choose a precious colored stone, inevitably, the conversation will turn to clarity. Similar to [Link] diamond jewelry appraisal in Houston [/Link], there are two things you need to know about clarity:
The gemstone will have Inclusions, which means there are minute amounts of minerals that make the stone unique. Rubies, sapphires and emeralds commonly have inclusions and they generally don’t take away from the stones’ beauty.
The gemstone will have no inclusions, or no trace minerals included in the stone. The most exceptional stones have no inclusions, like the aquamarine, topaz and citrine stones.


It’s not uncommon for a Houston jeweler to enhance precious colored stones. In fact, you should expect enhancements. Enhancements to emeralds, rubies and sapphires add to the visual properties of custom jewelry in Houston and boost its aesthetic appeal.

These are just a few of the enhancements that jewelers use on colored stones:
Infusion, an oil treatment, is generally applied to emeralds to maintain their color and clarity. Filling the stone with oil (or a resin or wax) boosts its appearance, and jewelers have been using the process for centuries.
Heat treatment is reserved for stones like sapphires and rubies. Only very durable stones can withstand heating without negative side effects, or damage to the stone. The stone is heated slowly to as high as 3600 degrees (or 2000 degrees Celsius). The process results in a higher color brilliance and cleaner color, because the heat can often remove inclusions.
Gemstones come from a variety of regions, including Kashmir, Sri Lankan Sapphires, Burma and Colombia. Some stones, like Kashmir sapphires, are rarer than other stones; however, conflicts in some countries have led to a halt in mining the already rare stones.
