Everything You Need to Know about Diamond Treatments

First of all, diamonds are a rare natural occurrence. Shaped underground over millions of years, your gorgeous diamond went through a remarkable transformation from a simple carbon rock to a transparent sparkling jewel. In that lengthy creative process, a diamond often developed natural inclusions inside the stone. People may refer to them as flaws or blemishes. Inclusions lower the clarity grade and affect the beauty, and of course the diamond’s value.

Today however, tremendous strides have been made in the diamond industry to improve upon the beauty and clarity of diamonds through methods of clarity enhancement. Let’s discuss the various enhancements to natural diamond that improves its beauty.


Laser Drilled Diamonds

One successful method of improving a diamond’s clarity and beauty is through laser drilling. This procedure utilizes micro-laser drilling into the area where an inclusion is present. The laser produces a drill area less than the width of a human hair, and produces clean results by entirely removing the flaws. This method is often the treatment of choice when the internal blemishes are dark (black) and quite obvious to the naked eye.


Fracture Filling

Fracture filling treatments use highly sophisticated laboratory techniques to force a clear substance into the flaws which make them seemingly disappear to the naked eye. The filling treatment is in a liquid state when it is forced into the stone. It’s important to note that this filling in no way disrupts the stone’s integrity. Diamonds are coveted for their remarkable durability. A fracture filled stone maintains that strength. And this is also important to know; the filling has the same optical properties as a diamond. Therefore, while it improves the clarity grade of the stone, it also aids in the appearance of a more brilliant and sparkling diamond.


Color Enhancement

As rare as diamonds are, once in a great while they are discovered in an array of naturally occurring colors. Of course finding such diamonds, also called fancy colored diamonds, is thrilling news. Those diamonds are often sold for hundreds or thousands of times more than their colorless counterpart.

Today the public is becoming more and more familiar with fancy color diamonds thanks to the celebrities seen wearing them at red carpet events. So technology offers diamond lovers an affordable solution to these pricey but colorful stones. Color enhanced diamonds develop their stunning hues in a few different ways: Irradiation, diamond coating, and HPHT (High pressure, high temperature) Treatment.



The technique successfully used in creating colored diamonds first occurred over a hundred years ago when a chemist used irradiation (chemical salts) in a controlled laboratory setting to produce a diamond with a dark green color.

Today that irradiation process has been refined to safely turn genuine earth mined diamonds into a rainbow of colors like vivid grass green or even turquoise blue. These colors are stable—meaning they will hold their rich tint forever.


Diamond Coating

The process of diamond coating is not a new technique. Early jewelers in Georgian and Victorian times (18th and 19th centuries) applied colored foils to the back surface of gemstones and created exciting new colors not found in nature.  But today, a more sophisticated approach based on the same idea is turning out sensational diamond colors including yellow or even violet. Modern surface coatings require a proprietary lab environment to vacuum coat a sheer film of color on diamonds with remarkably beautiful results.  These and other procedures are disclosed of course in their sale by reputable dealers so that consumers understand what they are buying.


High-Pressure High-Temperature Treatment

Did you know that small amounts of diamonds are discovered annually with a natural brownish body color? They are still attractive stones and have all the fine qualities of the colorless variety. But they are often singled out to be treated with high-pressure and high-temperature in the lab. This process is also called HPHT for short. The stones are subjected to extremely high temperature in a pressurized environment. The results are a whitening of the subjected stones, producing some alluringly colorless diamonds. Of course this diamond treatment is disclosed by reputable jewelers.

Diamonds in all forms are some of the most sought after valuable items throughout the world. Their sustained popularity is also due in part because these precious stones represent the love between two special people. Their durability reminds one of the unbreakable bonds of love that two people share.


Now that you know more about enhanced diamond techniques available today, you’ll have more knowledge to shop for your special stone. When you’re ready to make a diamond purchase you’ll be able to consider the remarkable milestones that science contributes in producing spectacularly beautiful diamonds. What was once out of reach in the diamond world to most of us is now affordable. Beautiful diamonds of all kinds are a lovely way to celebrate the cherished memories of our life. ♦
