"Love is not love which alters when it alteration finds"

This week i have mostly been obsessed with my new Shakespeare ring. It reads

"Love is not love which alters when it alteration finds"

it's from Sonnet 116. I'm thinking of buying another one because it's not real silver and i know I'll wear it to death and it will turn green. I'd love to find more Shakespeare inspired jewellery, but it seems to be a rarity.

Let me not to the marriage of true minds
Admit impediments. Love is not love
Which alters when it alteration finds,
Or bends with the remover to remove:
O no! it is an ever-fixed mark
That looks on tempests and is never shaken;
It is the star to every wandering bark,
Whose worth's unknown, although his height be taken.
Love's not Time's fool, though rosy lips and cheeks
Within his bending sickle's compass come:
Love alters not with his brief hours and weeks,
But bears it out even to the edge of doom.
If this be error and upon me proved,
I never writ, nor no man ever loved.
