Our Materials & Jewelry Care


Good things take time!

We care about craftsmanship and quality and that is why we take pride in making sure you're pieces last. 

You want to get the best quality for your investment, and we are here to do exactly that!

We primarily use Sterling Silver and 14k Gold in our collections, but for our more affordable Fashion collections we use brass that is micro-plate and e-coated so that your pieces last. 

What makes our Fashion line so different? The thickness of gold plating on jewelry can vary depending on several factors, including the quality of the plating process and the desired durability. In general, gold plating thickness is measured in microns (µm) or mils (thousandths of an inch).


For fashion jewelry or lower-quality gold-plated items, the gold plating thickness can range but starts as low as  0.1 microns (or approximately 0.0001millimeters). This type of plating is relatively thin and may wear off more easily over time. Terms to familiarize yourself with. 

Gold Wash/Flashed When you see term ‘gold plated jewelry’, this is the most cost affective plating used by many Fashion jewelry brands. Gold wash/ gold Flashed jewelry items are dipped in gold bath just enough to give an article a gold color and even finish, but they are less durable, hold an extremely thin coating and can tarnish much quicker, relatively in a few months. 

    Micron Plating When the gold coating thickness is above 0.5microns, it is referred to as "micron plating".

      We use 30+ microns or more to ensure you're pieces last above all.

For extra shine, sometimes we give your pieces a nice soak using our jewelry cleaner. Cleaning cloths are complimentary upon request and jewelry cleaner is free with a purchase of $250 or more.
