I just love clear crystal bottles specially this one here. Its all about simple but elegantly carved crystal art, anything inside would just add to the whole awesomeness. I used to have 14 of these bottles and gave away 8 of them to friends and customers. I usually put in my special natural designer perfumes in them .
H&D Clear Art Carved Crystal Empty Mini Refillable Perfume Bottle
H&D Clear Cubic Carved Decor Refillable Perfume Bottle
Opaque Glass Perfume Bottle with Purple and White Flowers and Butterfly By Haysom Interiors
Leolana Decorative Handmade Perfume Bottles - Green 6.5"
Leolana collection is just amazing, price ranges between 18 - 25 dollar a bit higher than other available option but you get a quality hand made piece of art. I am a big fan of leolana but for an alternate you can also look into perfume bottles by steel street. Leolana bottles are more towards glass craft side and steel street is well more steelish in looks bit both would add value to your perfume collection.
