The importance of friends in higher places is very evident today. On Odin is a high level Goldsmither (95+) who is a friend of mine, Binyabr.
Now, the problem with Platinum Earrings is that first you need to make a lot of them, and secondly, you need to somehow release them to the AH without crashing the market. Now, I had already turned a stack of Platinum Ingots into Platinum Earrings, and they were selling pretty slowly, but I had five more stacks to go and needed a way to get rid of all of them.
Enter Binyabr.
As a high level Goldsmither, he could use all the Platinum Earrings he can get. At his level, he can also try to HQ either Triumph Earrings or Communion Earrings for a
very nice chunk of change. However, that requires a lot of Platinum Earrings, which aren't exactly flowing out of the AH. Which is where I come in.
In the end, we agreed that I would sell all my Platinum Earrings to him at 140,000 gil each, which is 10k below the AH price- 7.5k if you count the AH tax into things. Sure, it's greater loss, but I wanted to be able to get rid of all the earrings en masse, which was what I was able to do.
So I went about turning all my stockpiled Platinum Ingots into Platinum Earrings. To give aspiring Goldsmithers an idea of how much Ingots you will need, I used up six stacks of Platinum Ingots before getting my level, which is a cause for celebration!

Sure, I took a slightly higher loss/synth than I would've had I slowly leaking out to AH, but I felt that the benefits for being at Goldsmithing 68 were worth it. First off, I get my Goldsmith's Apron. Now
that alone is worth the extra hit, but in addition to that, I can now squeak into the 51-tier for Silver Earrings and HQ them for a tidy profit. I am also in the 51-tier for cutting gems with Goldsmithing 68 + imagery. As such, the potential outweighed the immediate cash hit I'd be taking. Besides, these Platinum Ingots have been stockpiled for so long, I had grown rather not used to having the money, anyway. >_<
In retrospect though, I probably should have asked Binyabr to see if he can split some of the profits with me- it would've made my life skilling in the 70s slightly easier, and he's probably have an extra HQ for profit to himself. (And one more to cover the costs of the Earrings... -_-)
Ah well.
With Goldsmithing 68, I now had the opportunity to take the rank test to become a Goldsmithing Artisan. The test item was a Mythril Breastplate, which was sold out in Jeuno for 50k. >_<
So instead, I set about making it myself. >_<
The required ingredients were two Mythril Sheets, two Darksteel Sheets, and two pieces of Ram Leather. Instead of buying all the ingredients off the AH and synthing it, I decided to travel Vana'diel to get the ingredients myself the cheaper way.
This is in spite of just happily shelling out about a million gil skilling up. Crafting's funny like that sometimes. ^^
Once I handed the Mythril Breastplate in, I finally attained Artisan status at the guild, and with that, I immediately headed over to the guildpoints person, who now asked if I wanted to trade 100,000 guild points for a Goldsmith's Apron.
And so, I have what I consider to be my greatest accomplishment yet so far in my Goldsmithing career, and possibly even in game, although that and BLM75's up to further debate. ^^

So...happy... :D
