Frequently Asked Questions

Buying for yourself:
Lucky you! We’d advise that you refer to our ring size guide. Each style of ring differs from another and this may alter your usual ring size.

Do bear in mind that more delicate rings tend to feel looser, which may mean you wish to opt for a half or whole size down from your regular size. Meanwhile the wider the band/ring, the tighter the ring will feel, so you may find it more comfortable to choose either a half or whole size larger.

Be mindful of which finger you would like your gift/ring to fit on, as each finger size can vary a lot. Please also be aware that ring size can fluctuate due to weather conditions and fluid retention, especially during menstruation. It’s best to take this into consideration when measuring and ordering your rings.

Buying a gift:
Lucky them! There are several ways you can find out your recipient’s ring size:
1) Measure one of their rings.
Secretly borrow a ring of theirs that fits well (ideally a ring worn on the same finger as the ring you’d like to purchase, as fingers can vary a lot) and trace the inside circumference on a piece of paper. Then measure the diameter of the ring. The measurement will correspond to a ring size – check out our ring size guide.

2) Pop to the shops.
Secretly borrow one of their rings and ask a jewellery shop to measure the size for you. Again, try to borrow a ring that you know fits them, and ideally which sits on the same finger as the ring you plan to order.

3) Phone a friend.
Ask a close friend or family member if they know your recipient’s ring size. Just be sure to remind them to keep it a secret!

Don’t worry. If you have followed our instructions to determine the right ring size and there is still an issue, we can resize the ring for you. Please contact our customer care team via hello@codebyedge.com quoting your order numbers. Please be aware that there might be additional charges for resizing and shipping.

Lab-grown diamonds are produced in a very tightly controlled laboratory environment, designed to perfectly mirror the conditions in which mined diamonds develop deep below the earth’s surface.

Starting with a diamond seed and an external source of carbon (the key molecular component of diamond), extreme pressure and temperature is applied, allowing the carbon source to grow on the diamond seed, atom by atom and layer by layer. This process creates a laboratory-grown rough diamond that can be cut and polished in exactly the same way as mined diamonds.

According to the Gemological Institute of America (GIA), “a lab-grown diamond has essentially the same chemical composition, crystal structure, optical, and physical properties of diamonds found in nature”.

Conflict-free, safe to produce and every bit as dazzling as mined diamonds, these incredible jewels are an exciting and sustainable way to wear your heart on your sleeve. Or your wrist, or your finger.

Consumers often translate synthetic into ‘fake’ or ‘look-a-like’ and associate it with such materials as Cubic Zirconia or Moissanite. But lab-grown diamonds are chemically and optically identical to earth-mined diamonds. That’s why the FTC (the Federal Trade Commission in the US) has recommended the term ‘lab-grown diamond’ and ruled against the term ‘synthetic’.

Hydrothermal gemstones are created using the natural convection powers of heat and gravity, just as they are in the earth. Like lab-grown diamonds, hydrothermal gemstones offer a sustainable alternative that is physically, chemically and optically identical to their mined siblings.

We love them for their beautiful consistency in colour, and for the double-sided chequerboard cut which brings our necklaces, pendants and earrings alive. They move with you, filter light and shine from every angle.

Like many other global brands, we are facing the challenge of counterfeits. If you’re in any doubt as to a piece of jewellery’s authenticity, please contact our customer care team via hello@codebyedge.com.

To care for your precious metals, diamonds and natural gemstones and keep your jewellery’s natural brilliance, we recommend the following care instructions:

How to wear and care for your jewellery
– Remove your jewellery when you shower, bathe or engage in heavy exercise, particularly when swimming in the sea or in a chlorinated swimming pool.
– Be gentle – all of our gemstones are natural and therefore can be vulnerable to chipping and absorbing dirt. Settings may also become loose over time.
– Avoid spraying perfume and applying creams or any other liquids directly onto your jewellery.
– Keep your jewellery away from extreme temperatures, humidity and direct sunlight.
– Avoid wearing your jewellery when using bleach, cleaning products or other harsh chemicals.

How to store your jewellery
– We highly recommend that you store your jewellery in the original packaging provided, or another soft pouch or suitable lined box. If you live in a humid climate, place a small packet of desiccant crystals in the packaging.
– Ideally store your pieces of jewellery separately, so that they don’t rub together or become tangled.

Cleaning precious metals
– To keep your jewellery looking radiant, we recommend using a polishing cloth to remove the build up of dirt and any premature tarnish.
– A silver cleaner can be used to clean sterling silver pieces – but not 18ct rose or yellow gold.
– Do not use tissue paper or paper towels to clean metal, as they can cause scratching.

How to prevent tarnishing
– All our sterling silver products are protected with an anti-tarnish solution, but this may eventually wear away over time.
– Silver tarnishes rapidly when exposed to certain substances in our everyday lives so we recommend caring for, wearing and storing your jewellery as mentioned above.
