Features to Consider When Buying Green Diamonds (Buyer’s Guide)

Below are a few special points you have to consider when purchasing green colored diamonds. 

Color and Saturation

While the carat and clarity play a special role in grading a colorless diamond, a green diamond’s price and quality depend significantly on its saturation and color. Green diamonds with a strong, singular color come at higher prices than those with a secondary hue.

Also, check for visible blemishes or inclusions and consider the setting and shape that goes well for its color.

Shape

One way to retain and stress a green diamond’s shade is to pick loose stones in a cushion or radiant cut. They are the best cuts for green diamonds as they bring out more of its lush green hue. Other shapes that might diminish its color are far less common, making them expensive.

Treated Diamonds

While treated green diamonds are often cheaper, their color will fade over time. On the other hand, natural green diamonds can retain their intensity and sparkle. 

Certification

When buying an authentic diamond, the standard rule is that you should ask for a diamond certification from GIA or AGS. Although there are several grading institutions, the GIA and AGS offer consistent diamond assessments than other laboratories. 

Budget

When buying a colored diamond, make sure that you have prepared a budget. A green diamond with a deep green hue is expensive, while less vibrant stones are more affordable.

FAQs (Frequently Asked Questions)

What are the famous green diamonds in the market?

Since green diamonds are quite rare, only a handful of these gems are found. One of the most famous green diamond is the Ocean Dream. It has a unique fancy deep blue-green hue that mimics the crystalline image of a deep blue ocean. 

Meanwhile, the Dresden Green is the largest known natural green diamond weighing about 42 carats. There is also the Chopard Chameleon, a famous green diamond that can transform its color depending on the environment. 

Chameleon diamonds normally possess a green color but can transform from brown to yellow, depending on heat and light exposure. When heated or stored in the dark, they give off a bright yellow hue temporarily. When cooled down or gradually exposed to light, chameleon diamonds return to their original green hue. 

What are synthetic green diamonds?

Synthetic green diamonds are created inside a gemological lab under certain conditions that imitate the environment required to form a natural green diamond. Due to the identical process, it is tough to distinguish a natural diamond from a synthetic one. They are even submitted to the GIA to inspect their origin of color before they are released in the market. 

Among synthetic green diamonds, the rarest variety is the fancy green color, making it one of the most special gems. One way to differentiate a natural and synthetic diamond is by checking its radiation stains. Natural diamonds often have green or brown stains along their surface, which cannot be recreated in a simulated environment. 

What are treated green diamonds?

Artificially irradiated green diamonds are less expensive and more abundant. If you cannot afford a natural green diamond, a treated green diamond is a budget-friendly alternative. As many would believe, enhanced or treated diamonds are not fake diamonds. They acquire their green shade by exposing a natural colorless diamond to chemical or heat treatments. 

However, make sure that any diamond you will buy comes with a certified grading report from a reputable lab, such as AGS or GIA. This way, you can verify the origin of your newly-purchased colored diamond.
