Tanzanite Blue & Ultraviolet Colors in Edisons.. Another innovation.

[Yens]

The evolution of the Edison pearl continues to surprise even the most seasoned gemstone enthusiasts, marking a genuine breakthrough in natural pigmentation. While we have long admired the soft lavenders and high-sheen "metallic" pinks of previous harvests, a new era has arrived characterized by deep, saturated, royal purples. To see this level of intensity—entirely natural and free from any treatments—is a landmark moment for the industry. Even more remarkable is that these rich colors are appearing in substantial sizes, ranging from 13mm up to an astounding 17.5mm, a feat previously thought nearly impossible for organic gems.

Because these specific hues have never been available on the market until now, they represent a rare opportunity for collectors and designers alike. These pearls are the "impossible" made real, offering a level of velvety depth and scale that was once only a dream for pearl lovers. Owning one of these gems isn't just about the jewelry; it’s about capturing a piece of history from a harvest that is truly rewriting the rulebook of sustainable cultivation.

But, do they fade over time?

But, do they fade over time?

We learned that color changes over time is determined by how much processing was done to the pearls after harvest.
At the early stages of FWP Edison, farmers treated these natural colors like they would with white pearls. Optical brightening, high heat polishing, etc etc. Doing all of that is actually bad for the nacre and damaging. Yes, it did make the pearls look extra good, but changes quickly.

Now, producers would only do light wash with clean water and some may not even polish the pearls. This is to minimize damage to the nacre that they previously were doing. Hoping this would stabilize the pearls.

Lastly, the hybridization of shells has gone through several generations compared to when it was first released. Then there's length of growth in the water and age of mollusk used.

There are also other factors such as body oil, acidity of sweat, storage, etc etc.

Producers are learning from the past and improving the pearls. What we've seen on recent trip in China has shown new promising things for the future.
