This looks great on you! I love the oval chain. When I was deciding on what chain to go with my Tolomeo, my first choice was the oval chain. That was just based on pure visual as it is such a beautiful chain. hen I read about each chain, and the only reason why I went with the round is the writeup on the round chain said it would go well with Tolomeo, so I chose it for that reason. Visually, I love your oval chain.
A couple other tidbits...
Did you know there is a chain guide page? In case you cannot get to the link, I'll post the image below too.

My favorite chain is their Jean d'Arc necklace, which I thought about asking then to do a smaller version in 32." I thought that would be too much drama, and since the Jean d'Arc necklace has round links, I thought.. okay, I'll stick with the classic round.

I think the ribbon or classic round are both good choices, but the ribbon is alternating rounds and ovals, so you may find that too busy worn with the amulet as you may want the amulet to be the star, not the chain. Plus, you already have the perfect oval chain, so now you can have a round chain too. The chain guide gives you really good comparison visuals.
The vine amulet is gorgeous! I think the large is not big at all, as the width only 1.2" hence it's very wearable.
Speaking of your locket, did you know you could engrave it? In case you did not, you can engrave each limb of the tree to make it a family tree if you wish (scroll down to engraving):

For gifts cards... Perfume? Here's a thought for buying something you may not care about, but you may end up falling in love with. I'm a perfume person, and I love florals. Rose is a flower I love, but I have never quite been able to find the perfect true rose scent. I went to London a couple years ago, and in a weak moment, I let a sales lady spritz me with Jo Malone Red Roses cologne. I thought.. "ugh, you are going to regret this now, you will stink all day!" Well, on the contrary, I couldn't stop smelling my arm all day! I'm not really a Jo Malone fan, but this rose perfume is the bomb! I spray it on me all the time, even at night before I go to bed. It feels like I am surrounded by the scent of fresh cut roses all the time, subtle too, but you know it's there. It's very soothing, and I'm usually the bold white floral gal (e.g. tuberose, gardenia). This rose is a true fresh pure rose scent. No vanilla (yuck), no amber (double yuck), no patchouli (barf). Just pure unadulterated roses. So lovely.

Maybe blow your gift card on roses and try it!
