The Importance of a Quality Yellow Gold Butterfly Back

Losing an earring is always frustrating . Choosing a quality gold earring back is essential to protect your precious jewelry.

Our yellow gold butterfly back uses the traditional "Belgian" or "butterfly" system. This double-roller design creates a mechanical spring effect that firmly pinches the notched post of your earring. It is the safest and most comfortable type of earring clasp before screw-back or Alpa systems.

9K Gold (375/1000): Robustness and Affordability

Why choose 9k (375/1000) yellow gold for your earring findings?

1. Hardness: 9k gold is an alloy composed of 37.5% fine gold. Containing less pure gold than 18k, it is naturally much harder and more resistant to deformation. The rollers of your earring back will retain their elasticity and "grip" much longer.

2. Fair Price: Choosing 9k gold earring backs allows you to replace a lost earring back at a very affordable cost, while still using a noble and tarnish-resistant precious metal.

FAQ: Choosing and Maintaining Your Butterfly Backs

How to choose the right size back for my earring?

It is crucial to check the diameter of your earring post:

• If you have a delicate stud with a very thin post (0.60 mm), choose our Thin Posts model.

• If you have a designer earring or a heavier piece with a thick post (0.95 mm), opt for our Model for Thick Post. A post that is too thick forced into a hole that is too small will damage the clasp.

What to do if an earring back is lost?

Losing the back of an earring is very common. We sell these gold earring backs as a pair so you can complete your set. It's always useful to have a spare pair in your jewelry box.

How to tighten a gold butterfly back that slips?

Over time, the rollers of an earring back can slightly spread apart. To restore their full clamping force, small flat-nose pliers, such as tweezers, and gently squeeze the two outer rollers towards each other to tighten the central hole.
