What Brysing says is true, and tools themselves are not "necessary". They are only there to help the mind tie in what is happening spiritually with something he/she can see and touch with ease.
However, previous to Christianity, when magic was an accepted and even "necessary" part of religion and culture, fancy and elaborate things were common for those who had the wealth or skill to obtain them.
Egypt stands out in my mind most when discussing "over the top" tools. The pyramids themselves were placed specifically to coincide with astrological positions and pointed toward the heavens as perfectly built mathmatical structures. Their tombs, pure works of art! We know so much about them due to the amazing amount of detail and dedication they put into their religion and rituals.
The idea of it is that the material used (pure metals, precious stones, etc) resonated pure clean energy. This belief was later repeated in alchemy. "Fine" materials to this day are seen as "special" and used for things that have the most sentiment, in order to demonstrate utmost honor, respect, and care.
Putting a lot of effort into creating an object or structure was a spell in itself. The amount of focus and thought when creating it causes this.
People have always used art, architecture, etc to perform a magickal purpose. The Native American dream catcher, African masks, Ukrainian pysankas, even Catholic churches themselves are known for their "over the top" ritual tools (for mass) with matching "over the top" intricate statuary and archetectural detail.
But just a fancy tool or object isn't going to have any special purpose, in my opinion, unless it is hand crafted by the individual him/herself or specifically for the person who will use it.
