Aren't these lovely? I am always impressed by those with unusual engagement rings but there's the unfortunate risk that your intended will be thought of as a cheapskate for actually putting a bit of thought into the procedure and not just turning up with the usual boring old diamond. Sorry! Personally I don't like diamonds, I much prefer a bit of colour or just something with a bit of imagination. And something with less of a tainted reputation? Here are some favourites from Etsy:
I love black pearls, they have such a beautiful lustre to them and are so much more mysterious and exotic than their paler cousins.
Ok, you'd need to be particularly fun loving for this one, but wouldn't it just cheer you up every morning!?
This one is rather like my own heh heh. A lovely vivid blue.
And now I want them all!
