Diamonds and Gemstones

QUESTION 1: What is the difference between Diamond-cut and Faceted-cut gemstones?


Unlike diamonds, most gemstones are cut to save weight and enhance color. This means you can have bulging bellies and other symmetry and make issues in gemstones that you wouldn’t see in diamonds.

Diamond cut means the gemstone is cut closer to the standard proportions we see on Round Brilliant Diamonds. This can make setting gemstones much easier.

QUESTION 2: What is a lab-grown diamond?


Lab-grown diamonds are diamonds. They are not simulants like CZ. Instead of forming over millions of years in the earth’s mantle, they are created in rough crystal form by scientists. They are optically, visually, and chemically identical to natural diamonds.


QUESTION 3: What is the difference between synthetic vs lab-grown vs imitation stones?


Synthetic gem is a laboratory creation with essentially the same chemical composition, crystal structure, and properties as its natural counterpart. Other terms that are often used to describe synthetic gems are lab-created, man-made, created, and cultured. An imitation gem is any material that looks like a natural gem and is used in its place.


QUESTION 4: What are clarity enhanced diamonds?


Clarity enhanced diamonds are diamonds that have had additional treatments that make their visual clarity better. The two main techniques used are laser drilling and fracture filling. Laser drilling is used to burn away an inclusion or to create a channel where bleaching agent can be used to improve an inclusion’s appearance.

Fracture-filling involves injecting a feather with a glass-like substance to improve the stone’s apparent clarity. Stuller does not carry fracture filled diamonds.



What are color enhanced diamonds?


Just like all diamonds, color-enhanced diamonds are known for beauty, hardness, and durability. They require no special attention in daily use. By using either Irradiation or High Pressure/High Temperature (HPHT) methods, fancy colors can be achieved.

Some colors require both methods. These are considered permanent treatments as it would take extreme temperatures to alter the color. Stuller’s color-enhanced diamonds use the following methods:
