Sustainability 
 

All Mirra Tierra jewellery is made of recycled .925 silver. Recycled sterling silver is precious silver that is not mined from the ground. Instead, it is produced from extracting the silver from unwanted jewellery, scrap silver, electronics, even medical equipment or other used metal products. I also use precious and semiprecious gemstones for my designs that come from responsible sources and can be traced.

In an attempt to reduce the environmental impact of my work, I also try to use less harsh chemical materials and techniques that are more environmentally friendly in the jewellery process and sustainable packaging. Mirra Tierra jewellery is packaged in an eco velvet pouch inside a 100% biodegradable kraft branded box accompanied with recycled paper cards, postcards, handwritten thank you notes and eco-suede pouches. 

 

Ring Size Guide

Most Mirra Tierra rings are adjustable so that you will be able to style them on different fingers and mix and match them any way you like!

However, in order to ensure the perfect ring fit, please check the following tips:

-The best time to measure your finger size is at the end of the day and when your fingers are warm, because in the morning or when it is cold fingers may be a bit smaller. Maybe measure your finger size a few times for more accuracy.

How to measure your ring size

1. Use a soft measuring tape, wrap it around your finger and note the measurement.

2. Wrap a piece of paper around the intended finger and mark with a pen the spot where the ends overlap. Make sure that it would allow for the knuckle.

3. Measure the inner diameter of a ring you already have and fits the intended finger. Make sure not to include the thickness of the shank itself.

Once you have your measuments, you may consult the following table and add the Ring size in the note section of your order or choose the preferable ring size on the dropdown list on the product page.
