Which name is better?

[Robin]

I am starting a business called Daydream Box. That is the umbrella name.
However, I am having a branch shop for jewelry. You can see it here: http://www.daydreamgems.etsy.com

My question is, should I call it DaydreamGems or would it be better to keep "Box" in the name so people associate it with my main business (e.g. Daydream Gem Box or Daydream Jewelry Box). I`m worried that "Gems" implies gemstones rather than jewelry.

Which name would be best for marketing/SEOs?
1) Daydream Gems
2) Daydream Gem Box
3) Daydream Jewelry Box
4) Other (your suggestion)

Thanks for any help!
