We talk a lot about transparency and traceability, but one area we don’t think gets talked about enough (in the industry as a whole) is cutting. As cutters ourselves, we thought sharing a ‘Cutting 101’ of sorts could be helpful. Sometimes just understanding the basics of a process can help develop or form questions you might want to ask when buying your gems. So, here’s our 101 crash course of what it looks like to facet a gemstone. We also love your feedback!...

Working With Emeralds

Working With Emeralds

Many believe emerald to be a softer gem type but in reality, it is a variety of beryl just as aqua, morganite or our signature Neon Green Beryl™. All beryl, emerald included, is actually quite hard at 7.5 on the Mohs scale. The misperception of it being ‘soft’ is likely due to emerald frequently displaying small open cracks and inclusions, which can weaken the structure of the stone. While it is a hard gem, it does have some brittle qualities due to the harsh geological conditions in which it forms. This also means emerald is nearly always included. These inclusions...

May Birthstone: Emerald

For centuries pharaohs, emperors, kings, and queens have used emeralds in their royal adornments.

Fair Trade Friday: Benefits of Traceability

Fair Trade Friday: Benefits of Traceability

Can you name the benefits of traceability? When it comes to colored gems, there are some obvious (and important) answers like knowing the origin or understanding how it’s mined and produced. But what are the less obvious benefits?One benefit we wanted to talk about is how working with a supplier who is involved in all stages of the supply chain will go a long way in eliminating problems such as non-disclosed treatments, synthetic materials, or imitation gems being introduced into the market.This by no means is a comprehensive conversation about all the benefits of traceability but these are a couple...
