Lab Grown Diamonds 

 

Our diamonds and gems are optically, physically and chemically identical to earth-mined gems, with the same beauty and endurance. The difference? Less impact on the environment.

All of our lab-grown diamonds .50 ct and above are certified and  feature a microscopic laser inscription of the certificate number on the girdle, just as mined diamonds are often laser inscribed with a certification number.

Lab Grown Gems

 

Lab-grown gemstones, also known as synthetic or cultured gemstones, represent a significant advancement in gemology. These gemstones are meticulously crafted in controlled laboratory environments, where scientists recreate the natural conditions that lead to gemstone formation. This process involves replicating the extreme pressure and temperature conditions that exist deep within the Earth, where natural gemstones are formed over millions of years.

In terms of quality, lab-grown gemstones are virtually indistinguishable from their natural counterparts. They possess the same optical, chemical, and physical properties as natural gems.

Recycled Metal

 

As stewards of the environment, we are proud to offer 100% recycled gold and other precious metals supplied by Hoover and Strong and certified by SCS Global Services.

This means that purchasing our jewelry does not contribute to the demand for mined gold, which can be associated with undesirable environmental and/or community impact.

Recycled gold is identical in content to non-recycled gold. It is refined to its purest 24kt form and then realloyed to a karat level suitable for jewelry, such as 14kt or 18kt.
