GOLD:

 What's the difference between gold filled, gold vermeil, gold plated and solid gold?

Let’s talk about it! There are so many options when it comes to purchasing gold jewelry now of days so I wanted to give you a rundown on the different types so you can make the best decision for your style and budget!
.
There are no BAD types of gold, let’s start with that. They all serve their purpose in the jewelry world but brands want you to be confused when shopping so they can charge you whatever they want! That is not the way I do things at Halie & Co. transparency today and always!
.
I make 95% of my jewelry in gold filled and the last 5% in solid gold. As a trained metal smith I have gotten to work with all types of gold and feel that durability for everyday wear is most important to me and the jewelry I put into the world. That being said I want my jewelry to be accessible to various styles and budgets and working solely in solid gold would isolate a group of people (me included!) from getting to treat themselves to new stylish pieces that can change and adapt and last with your lifestyle!

I’m an open book and I love talking about all things metal so if you have any questions let me know!
