Diamonds and Sapphires

We offer conflict free or Canadian diamonds, sapphires and all other coloured gemstones.  Pick the centre stone that fits your budget.  If you prefer a lab grown diamond, that can be supplied as well; however, please read the following article about the misleading advertising of lab grown diamonds from the Federal Trade Commission in the USA issued May 15, 2019:

Last month, the Federal Trade Commission (FTC) shocked the industry by sending out warning letters to eight sellers of lab-grown diamonds and diamond simulants.

The move received a lot of attention, as it’s unusual for the FTC to do any kind of enforcement of its Jewelry Guides—never mind sending letters to eight jewelry companies at once.

In response to a Freedom of Information Act request, JCK recently received the eight unredacted letters, all signed by James A. Kohm, the associate director of the FTC’s division of enforcement. 

Three of the letters were sent to companies that exclusively sell lab-grown diamonds—Ada Diamonds, Diamond Foundry, and Pure Grown Diamonds—and the other five were sent to companies that sell diamond simulants—Agape Diamonds, Diamond Nexus, MiaDonna & Co., Stauer, and Timepieces International. Some of the simulant sellers, including MiaDonna and Stauer, also sell lab-grown diamonds.

The letters to the three lab-grown diamond companies advised that sellers of man-made gems should clearly and conspicuously disclose their stones’ origin. The Diamond Foundry and Pure Grown letters cautioned against using non-FTC-recommended terminology, such as “real diamonds created in California” and “above Earth diamonds.”

Kohm acknowledged in the letters that the companies all had portions of their websites that disclosed that their diamonds did not come from a mine. But “consumers could easily overlook” that, he said. Two of the letters also suggested that solely including a #labgrown hashtag may not be considered sufficient disclosure in a social media post.

The FTC also cautioned the companies not to make “unqualified general environmental benefit claims”—such as using terms like environmentally friendly and sustainable—”because it is highly unlikely that they can substantiate all reasonable interpretations of these claims.”

While there are differences of opinion on the environmental impact of man-made versus mined diamonds, the FTC does not seem to be endorsing any side of that argument. It is simply cautioning companies against using those terms and making those broad overarching claims.
