That is a good question, one that I have heard a lot in recent years. I am going to share my perspective on this with you from my experience, so that hopefully you can soon make a good choice based on a clear vision and a piece of wisdom.
So, the question: Is a large crystal more energetically powerful than a small crystal? My answer to this is No, it doesn't matter a BIT LOL.
I'm going to explain to you why I see it that way.
Crystal Consciousness
A Crystalline Being has his/her own consciousness & Spirit, just like you and I simply IS. One is not better than the other, BUT just like us, each individual crystal has its own frequency, blueprint, Wisdom, operation & set of abilities. No matter how big or small a crystal is, it remains as it is. It does not mean that a large crystal has a large consciousness and a small one has a small consciousness haha you understand where I am going.
So in this case the answer is NO. Absolutely not!
Crystals & Rarity & Codes
You have different crystals that vibrate at higher frequencies, these are often the coded crystalline beings, such as various Lemurians, but also think of moldavite.
In addition, you also have many rare Crystals that come in smaller Crystalline bodies. It just depends on what attracts you. Moldavite, for example, is super powerful and moves at a high frequency and touches deeper layers. But it does not come in a gigantic crystalline body as you see with, for example, a rock crystal, but in a smaller one. This doesn't detract from how Crazy! its power and impact.
Great Crystalline Beings
Crystals that come in a Large Crystalline body still carry their Organic Consciousness.
But (now comes the but) because of their Larger Crystalline Body this does make a difference on another layer.
A larger Crystalline Body can carry & absorb more energy from the environment and then transmit it.
Although more energy is released, and you can certainly use this if it has been properly programmed and taken care of, it makes no difference in terms of operation/downloads that you can receive on the Multidimensional layer.
There is just a little more storage space available for subtle energy and you can feel it.
To go into this very briefly, imagine you have a gigantic rock crystal, it is in your living room and you have programmed it to keep the energy in your house clear.
This energy remains present in your home for a while, allowing your rock crystal to absorb it all into its crystalline Body. This in turn creates a Dance between the Space & Your Crystal, think of it as an energetic communication or exchange. This makes it easier for you to receive subtle energies in, for example, the mental/emotional area from the Basic Frequency of your programming.
Super beautiful of course, but it is completely up to you what feels right for you.
A Crystalline Being calls you based on Consciousness level and whether it is a Mini, Small, Medium or Tripple XL makes no difference at all. It's all about the call and what you need and prefer at that moment, of course.
If that is a Giant Rock Crystal in your space or a Large Crystal to meditate with, do body work, guide your Plant Medicine Circles, etc., it is completely up to you ;)
I hope I have given you more clarity here regarding this question.
Do you have more questions you would like to see addressed?
Then I am always open to commenting below if you have any questions and I will certainly get back to you ;)
I wish you a nice day & Organic Flow ;)
