I would because my ATF is priceless in my mind.

My advice is do what you are comfortable in doing because if you think that she is worth it and you can afford it then do It. for one you eventually feel good and comfortable with her and other things. You just be wise and smart whatever decision that you make.

How many AFTs?  
How often do you . . surprise her with a "gift"?  
Has it become a routine?  
Do you think it has become an expectation?  
How long (not the session) are your ATF's tenure... on the average or is she "the" one ever?
So on how many ATF's (at a time)?  I say this because you are truely my ATF!  (Wink wink)
Maybe a quantity discount is in order?  So another man's 300 is another another one's 3K!  Confused?  It is what this hobby is all about. To take us to that edge of fantasy and blurred reality.

 
Enjoy while "it" lasts cause you can't take "it" with you!

Ok, that was my attempt at a Yoda.

Like Big Joe, if it is what you want to do, and you can afford it, then do it. You worked for the money dude, do as you wish.

Since you are asking for some counsel, let me offer it.  What are your expectations in giving it to her, and what are hers in accepting your most generous gift.   Also depending on her taste she may not like it.

As with any gift giving to a woman, it is not the cost of the gift that matters it is the investment that you made of yourself to obtain it.  Two examples;

1.  There was once a young lad during the depression that spent 4 weeks plowing fields so that he could purchase for his mother a dress. He thought that it would bring joy to her. He saw her admire it in the window. During the depression that was a total luxury, but he thought it worth it.  So, every day, while looking at the back end of a mule, this very light weight 11yo lad was thinking of the joy for his mother the entire time.  That was his investment not his purchase of the dress itself.

2.  A more modern example.  Have you ever noticed that upon receiving a gift, many women will ask the male provider of the gift "when did you get this?".  She asks this because she wants to know something very important to her.  What did I forego in getting it for her.  That is what touches her.  Lets say for this example, the lady (now of course this lady must have great legs and men get neck strain trying to look up her skirt) ascertains that I got it on a Monday night.  Well she knows also I always watching Monday Night Football with Big Joe.  Always, it is a highlight of my week. Then she thinks "he gave that up one night to find something that I might enjoy".  That touches her. In the real world she is thinking "that is major positive points, I am going to fuck him tonight until he is stupid". She sees the giver of the gift more than the gift itself.

Beyond the mutual expectations in the gift, will she see only the gift or will she also see and appreciate the giver of the gift. Many of us see the former and forget the latter.

Do as you feel led, but do so with eyes open.

Yes, to the wise Big Joe do you listen.......

Question number one. Does it make her happy?

Question number two. Does it make you happy?

Forget all about question number one, if the answer to question number two is YES, and of course if you can afford it, then who gives a fuck what the rest of us think, make you and her happy.

One caveat however. If you think you are "buying" her love, STOP, stop right fucking now and reconsider what you are doing. As long as that is not the case and you are doing this simply to make her, and you of course, happy then by all means knock yourself out.

Not passing any judgements on whatever you decide, but 2 questions to consider:

1. If your ATF told you she would not provide you with intimacy again, would you still give her the necklace?

2. Would your ATF give you a similar "gift" based on her esteem for you?

Whatever you decide, make yourself happy, Bro

I wouldn't even buy my wife a 3k necklace, or even a $200 necklace.  It's just jewelry, it doesn't do anything.  At least that's why I wouldn't do it.

If it makes you happy, then fuck it, do what you want. It's her (I mean your) money, do what you like.  I would suggest that you ask yourself, since it is your happiness that you are buying, it THIS the thing that would make you most happy?  Would you rather buy her an HD 80 inch TV instead?  Would you rather buy her a computer, or something . . . better (like a cruise or vacation)?  Then maybe you should also ask yourself, would you rather get more things that are less expensive and give them to multiple ATF's?  Or maybe you would also be happy donating the money (though probably not). All these would be questions as a function of your happiness.

If you feel determined to buy THIS exact thing for this EXACT lady, then I would add that you must absolutely NOT give her this gift on her birthday.  And you should not be in the habit of giving her expensive gifts.  And it would be preferable that you don't give her a birthday gift at all.  Maybe be out of town, or don't mention it.  You MUST give it to her EXACTLY when it is UNEXPECTED.  Giving nice gifts on birthdays and Chistmas, just mean that they are forgotten and less appreciated, as they are somewhat expected (maybe not so nice a gift, but a gift nonetheless is expected).  And buying a 3k necklace for a girl you bought a Ferrari for would be equally as meaningless.  You must give it to her for NO REASON at all.  Exactly how you came up with the idea, you just saw it on another lady, and had to get it for her; waiting until her birthday is just you giving a reason, and a reason that will lessen the impact of the gift at that!  Getting flowers of Valentine's Day means less than nothing, getting flowers just because means everything.

A couple more questions to ask yourself:
How will the lady view this thoughtful, and generous, gift?  
Will she see this as a sign that you want something MORE than a provider/client relationship?

Just my 2 cents. Good luck with your decision!

Yes, those are good questions to ask. A gift "too" expensive will send some women running in the opposite direction as fast as their feet will carry them.

Give her a "pearl necklace."

a client/friend gave me as a gift before we headed to Vegas for a black tie event at the Bellagio.  It is a beautiful necklace and I'm sure he has no regrets of giving it to me. Even though he's moved away and I don't get the chance to see him as much, I think he still loves seeing me wear it in all my pictures as a reminder of the friendship and fun we've had together.

Yes, VERY classy post... Gifts that are just bought without meaning are thought are only worth as much as that... No matter how much money you spend.  If you know something will hold meaning and it makes you feel good to do it, then DO it.  Money is all relative to your financial stability...  I know that I get more joy in giving to others than receiving.  However, I find the things that are going to make them feel very special, it it truly unique and they will cherish no matter how much money I spend on it.  

Its Cliche, but its the thought that counts And, necklaces are a very intimate gift if you think about it... As they are hanging close to your heart

You, in the end, will feel like a dummy.

She had helped me immensely in another area of my life and I wanted to show her my appreciation. Believe me, she showed me her appreciation for the jewelry...repeatedly.

It’s your $, if you feel that she deserves it then why not?

I was seeing an ex ATF for many years. Hung out outside of the hobby, she would call to chat, even invited me out off the clock. Then one day...GONE. Vanished like a fart in the wind. No texts, no calls...nada. Supposedly retired. Good news is I was reasonable with the gifts I gave...a spa day here, a shopping trip there. All in all, only $500-$750 or so. Keep in mind that at the end of the day, you are a customer and at closing time, the doors are locked and they leave.
