Well, for things to work out "easily" or "luckily," you would probably do better with divisions of 6 than with divisions of 7 or 8. The last amulet you posted looks more "prosperous" than the first one. Personally, I would study every tiny detail of the amulet before I wore it. I would want to know what the 5 lines of Hebrew say, what the 16 Hebrew letters represent within and around the hexagram, what is each kind of stone and what does it mean, etc. There are tons of symbols, stones, colours, and arrangements all over that amulet. It should take about a day to fully investigate it, if you have the right resources. If you have to hunt for information, it could easily take longer. Doing the proper research is always worth it, though. Don't ever try to use something without knowing what it is. It is very possible to get exactly what you want in an amulet and then accidently harm yourself by using it incorrectly. Once you know what it is and how it is supposed to function, you'll be much better able to make decisions about it. Fortifying yourself with a bit of prayer first might also be a good idea.
