Brimming with elegance, the moonstone is an awe-inspiring gem that has won the hearts of people all over the world. And while many want to own this stunner, very few stop to question its origin.
If you’re one of them, then we highly recommend reading the rest of this article.
Quick background
The moonstone is a semi-precious jewel available in a variety of hues, which includes white, yellow, black, grey, green, etc. True to its name, this gem showcases an alluring moon-like adularescence, which is the main reason for its fame.
An interesting fact about the moonstone is that it is also one of the birthstones of June and is often considered a great alternative to pearls.
How is it formed?
A part of the orthoclase feldspar group, the moonstone is a mineral consisting of potassium aluminum silicate. This jewel’s formation begins with the intermixing of two different minerals – orthoclase and albite, under extreme pressure and high temperatures. This process is then followed by the separation of the intergrown minerals into stacked, alternating thin layers during the gemstone’s cool-down period.
These stacked layers play a huge role in the stone’s unique shine. Instead of simply reflecting light, the layers soften it and cause it to bounce around inside the gem. This creates a mesmerizing optical illusion known as adularescence that resembles the reflection of the moon on the surface of the calm sea.
Is this gem treated?
Most of the moonstones available in the market today are untreated. However, in certain instances, the gems are surface-coated to highlight their adularescence.
How do you pick the perfect Moonstone?
Below we’ve mentioned some important factors that one must take into consideration when picking the moonstone.
1. Color
As touched upon before, the moonstone can be found in both a colorless state and even in white, brown, green, black, and grey hues.
- The best pick: The body color of the stone is typically a matter of personal preference. However, near-colorless moonstones with an electric blue shimmer are the most sought-after. Also avoid stones that display yellowish, brownish, or unattractive green tints.
2. Clarity
A jewel’s clarity refers to the relative absence of any imperfections that could affect its glow or brilliance.
While moonstones generally lack any visible inclusions, they can develop cracks that run parallel to each other. This is due to the extreme pressure under which they were formed. Needless to say, these cracks can negatively impact the adularescence of the stone.
- The best pick: When buying a moonstone, ensure that it does not have any visible cracks or inclusions on the surface.
3. Cut
A good cut enhances the stone’s shine and camouflages any imperfections that could lower the value of the gem.
- The best pick: Round and oval moonstones are extremely popular. Both these versatile options maximize the gem’s adularescence and infuse the piece with undeniable sophistication.
With its soft and unique look, the moonstone is a great gem for all reasons and seasons. The fact that it is a birthstone further adds to its desirability. And now that you know how exactly it is formed, we’re sure that this gem will be a great conversation starter!
So go ahead and bring home a moonstone masterpiece.
