Shape & Colour

Our lab-made/Recycled, conflict-free gemstones are in completely identical to those that are mined. Their chemical makeup and stunning aesthetics are the same. Radiance and a stunning array of color is what define gemstones. It is important to look at a gemstone’s tone, color saturation, and hue when deciding what gemstone is right for you.

Purity of color is what establishes gemstones as valuable. In addition to the primary color of the gemstone, they typically carry slight hues of other colors as well. If they carry only trace amounts of other hues, then they are considered to be of a high value. For example, some rubies may be described as having a color of “orangish-red” or “purplish-red.”

Tone refers to the gradation of the gemstone form “colourless” to “black.” They are described in terms of their lightness and darkness. The depth of our gemstones is highly sought-after, falling within the medium-light or medium-dark depth of gradation.

Saturation describes how vivid the gemstone’s color is, and this is rated based upon how much grey or brown a gemstone shows. The most valuable gemstones have very trace amounts of grey or brown, meaning that their color saturation is especially vivid and strong.

Identifying Marks The identifying marks of the gemstone refer to the unique inclusions and composition of trace minerals that are present in each and every gemstone. These generally do not take away from the beauty of a gemstone.

What to look for?

Each variety of gemstone requires different standards of clarity. Some, such as aquamarine or citrine, will have far fewer inclusions than an emerald or a ruby, for example. Some variations of gemstone will simply have more inclusions, but this does not mean that they will detract from the gemstone’s beauty.

It is important to consider clarity when you compare quality gemstones. Some will have inclusions that do impact their overall appearance. Typically, a moderate amount of inclusions is a satisfactory balance of value and pleasing aesthetic.

DiamondGarden’s colored Gemstone Enhancement Policy

All of DiamondGarden’s lab-made/recycled gemstones are heavily inspected and held to the highest standards of quality.

Because gemstones possess visual properties that are highly unique, the majority of fine natural gemstones are enhanced by centuries-old techniques. Gemstones that have not been enhanced are incredibly rare and, therefore, they will come with a much higher price tag.

You can learn more about the most common ways to enhance gemstones in the descriptions below:

Heat Treatment

Heat treatment is a standard procedure designed to polish and finish the gemstones. It enhances the color of gemstones permanently and is approved by the American Gem Trade Association


Infusion is when a gem is filled with a foreign substance to enhance its overall appearance. These substances can include oil, wax, glass, resin, or other materials. This practice makes the gemstones look clearer, and it a practice that has been in place for centuries.


A coating made of wax, resin, or oil is applied to the gemstone to offer protection to the substance and improve the appearance of the jewel.


Bleaching lightens or enhances color consistency.


Dyeing a gemstone enhances or alters its color.


Radiation is used to alter the gemstone’s color. Typically, the gemstone is then heated. The changes that take place with this process is permanent.

New and Future Technologies

New technology designed to enhance the color of gemstones is continuously being developed. Through any new changes, we are dedicated towards detection and full disclosure, and we always remain committed to the absolute highest quality.

Basic Gemstone Care

Although gemstones are strong, it is wise to care for your gemstone and to reduce the risk of damage that could occur from substances such as household chemicals. Please review our guide below for tips on how to properly care for your gemstone.


Clean your gemstone using jewelry cleaner that is non-abrasive. The cleaner should say that it is safe to sue on your gemstone. You can then use a cloth to remove any residue that might remain.


It is important to separate your gemstones by wrapping them in a soft cloth or keeping them in a lined case. Gemstones can scratch the surfaces of your softer jewelry.


Although gemstones are known for their durability, they are not indestructible. Cleaning chemicals and especially abrasive surfaces can damage your gemstones. Treat them with care and they will last into future generations.
