I think that this forum allows for a bit more of an intimate approach to replying, and so I'm going to offer a bit of personal criticism to this poem. Please don't take it as something negative, by any means... I mean only the best, because I genuinely respect you and your craft.
In a poem such as this one is, where you are allowing yourself to simply sit back and reflect upon something ("gifts" as you aptly deemed them) in nature, it helps that you re-create the scene such that it is pleasing to all of our senses, rather than giving us your more direct interpretation without placing within us those things that so inspired you.
In particular I would like more concretization, meaning... more colours, textures, simple actions... when you look at anything and bring it to us, it's helpful to present it with a verb if at all possible, to make the scenery more alive. One thing that poetry is capable of doing, that many other more visual art forms is not, is working with time and linear progression---you might benefit from using this a bit more primarily in your writing.
You do this well enough, but it seems that you don't do it consciously enough---do you know what I mean? For example, I love the past tense that you use... it's extremely helpful in a reflective piece, and makes the narration seem more intimate and real.
My favourite line is here:
As I turned them over and over within my grateful hands,
An example of how action in scenery can be effective.
I would have liked a bit more concrete description, earlier on, before your conclusions were presented.
Otherwise, I enjoyed this as I always enjoy reading you. You're a brilliant woman, and your approach to poetry is very respectable, as you've learned to reflect upon your subject matter and present your conclusions in the form of poetry, instead of merely your reflections. That's a practice I absolutely adore, and mourn the loss of in contemporary poetics... but something you seem to want to keep alive and kicking.
Would you mind if I asked what poets have influenced your style? I'm intrigued---
