The patent restricting sales to the US has fully expired(!), so there are no restrictions on sales or shipments of our Amora Gem to customers in the US.
Moissanite (technically, Silicon Carbide) is currently protected from being cut into gem form by a patent held by Charles and Colvard in approximately 26 countries.
The US patent expired on August 31, 2015, with patents covering most other countries expiring in various months in 2016. Mexico is an exception, with the patent covering those sales until 2018.
This patent covers multiple Silicon Carbide crystal types, including the one specific crystal type marketed as 'Moissanite by Charles and Colvard' (and technically known as 6H-SiC).
Note: Silicon carbide has many crystal variations (polytypes) and is a large family of crystals with over 200 members. 'Moissanite' is simply the one that is currently the easiest to grow and the first to be marketed as a gem.
Therefore, other Silicon Carbide crystal gems, such as Amora Gem which is a different member of the Silicon Carbide family, or Moissanite cut by other parties besides Charles and Colvard, cannot sell their gems into the following countries:
Silicon Carbide Gemstones – Patent protection is in effect until 2016 on most:
Note that the patent in Korea was thrown out due to "lack of innovation" and thus customers in Korea may purchase the Amora Gem.
Until the patents in the above countries expire or are invalidated, we cannot sell any Amora H&A (Amora GEM) to customers in those countries.
Customers in the above countries can purchase our Amora enhanced Moissanite, but again, cannot purchase the Amora H&A lab gem.
US and Indian reservations: A question we have received from those who reside on Indian reservations within the US - most Indian nations are exempt from US patent law and Amora Gem can be shipped there with no restrictions. This is also for example, why gambling can be done on an Indian reservation - they are each sovereign nations within the landmass of the US.
