Lab-Created Stones from Chatham
Here’s what Chatham has to say about their stones –
"Chatham does not make gemstones, we make environments in which crystals grow naturally."
You love Chatham's diamonds and gems, but you may have some questions. We'll try to answer these questions below:
Are Chatham gemstones real or imitation?
They're real. Our gemstones and diamonds are cultured just as many pearls; natural components are placed in an environment created to duplicate nature's. Once the required combination of chemical and environmental factors is created, the crystals grow over the course of a year, the length of time depending on the gemstone. As a result, quality diamonds and gemstones are developed with identical physical, chemical, and optical properties to those found in nature.
Can I tell the difference between created gemstones and mined gemstones?
Unless you're a certified gemologist with a powerful microscope, you won't be able to tell the difference between created and mined gemstones. Every gemological laboratory in the world has reference samples of Chatham gemstones to aid in the separation. Chatham is at the forefront of full disclosure, contributing samples and updates whenever something new is released.
Why do Chatham gemstones and diamonds often look better than their mined counterparts?
Under laboratory conditions, computers control temperatures, while foreign materials found in the earth are eliminated from our starting chemicals. This makes our crystal growth more predictable and consistent. We strive for the best qualities and colors found in nature. Lower qualities are not released for sale.
Are there cost savings with Chatham gemstones?
Significantly! Price differences between Chatham created and natural gemstones of like quality are notable, sometimes as much as $100,000 per carat as in the case of colored diamonds.
Does Chatham offer a warranty?
