Piece of my Heart Necklace

How to measure your ring size:

Follow these directions to measure your finger. They will give an approximate guide to establish your ring size. 

1. Find a piece of string or strip of paper no wider than 1.4 cm (1/2 inch).
2. Wrap it around the base of the appropriate finger.
3. Use a pen to mark the point on the string/paper where it overlaps, forming a complete circle.
4. With a ruler, measure the length from the starting end of the string/paper to the pen mark.
5. Use the chart below to determine your ring size.

But please bear in mind we can not be held responsible for any readings taken this way.

Here are some tips to make your ring size measurement more accurate:

• After sliding the ring sizer on, make sure it slides off fairly easily over the knuckle.
• Don't measure cold fingers. This is when fingers are their smallest
• For the most accurate reading, measure the finger at the end of the day when the finger is the largest.

Care Instructions:

All jewellery will naturally tarnish over time. Tarnishing is not a fault and steps can be taken to ensure your jewellery does not tarnish.

Use a soft lint free cloth to clean silver.

Ideally store your Jewellery in a dark, cool and dry place in a box, this will help to reduce tarnishing, scratching and tangling.

Silver is a bendable precious metal, any pressure applied could cause damage. We would advise when transporting that your jewellery is kept within a box so no external pressure is accidentally applied.

Gold plated silver may fade if the care instructions are not adhered to. Please do not expose gold plated silver to water, perfumes or lotions as this may cause the plating to fade. Gold plated silver may naturally fade over time.

We recommend that you remove jewellery while in water and avoid spraying perfume or applying creams where your jewellery will have contact.

Avoid extreme temperatures, humidity and sunlight. Any contact with perfumes/ cosmetics and chemicals will cause discolouration to metals. This is not a fault and can be avoided by caring for your jewellery as detailed above.

Sensitivity and allergies to metals:

Although allergic reactions are rare, some people are sensitive or allergic to certain metals and finishes commonly used in jewellery. Zo&CO will not be held liable for any allergic reactions that may occur wearing our jewellery.


Brass, Copper and Alloy Metals may cause discolouration when exposed to high acidic skin and chemicals. If you are prone to greening skin when wearing these metals, we would advise you to purchase jewellery composed of metals such as 925 Sterling Silver, Titanium or Stainless Steel. These are Hypoallergenic Metals and will not cause greening or discolouration. Unfortunately we cannot refund or replace any items if greening occurs as it not our responsibility due to certain individuals reacting different to Brass, Copper or Alloy Metals.
