Comment: Bolder opal in pendant-only-size. Charmingly colored veins in wavy patterns. These blue, yellow, lime and orange flower-adornments are the result of a purely geological process. The 'How?', and even more the 'Why', are open for speculation. If pursued long enough, the 'how' may be explained, but I doubt we will ever know the 'why'. As in: Why would a stone grow with similar patterns of beauty as nature will do millions of years later? A reason I can suggest, is that the unanimated 'stone' and biology shared the same higher source of beauty, which, millions of years later, blossomed again in flowers and trees. A joint universal essence of beauty that resulted in similar appearances whether in stone or flower. A fascinating thought, or I'm plain nuts. But remember the works of those mathematicians who discovered pattern of natural beauty when their formulas were displayed in visual media? Or are we, with eyes coming from the same essence, the true connection? The thought is worthy our time, because the DSEF report guarantees, amongst others, that those colorful patterns have not been painted-on by permanent markers in some Asian sweat-shop but have really grown long before biology had started the journey that resulted in us holding the stone today. See also the side-images, how the patterns reach below the surface, as one would accept from roots. Ask us for a setting, or drop me a line on the universal roots of aesthetics. Happy to learn anytime.
