Choosing a ring size
Don’t know your finger or wrist size? You can refer to our simplified size guide :
To find out your size, wrap a tape measure around the finger that will wear the ring, at the joint (where the finger is strongest). Read the value in millimetres. For example, if your finger circumference measures 52 mm, your ring size is 52.
If you hesitate between two sizes, choose the larger one.
Measure your finger at the end of the day. Do not take measurements when your finger is hot or cold. The measurements vary slightly from hand to hand. A ring worn on a finger on the left hand will not necessarily be the exact size of the same finger on the right hand. Make sure that the size you choose allows the ring to slide easily along the length of your finger.
Maintenance advice
Over time, dust, pollution and daily wear and tear reduce the brilliance of the stones, tarnish the gold and weaken the settings.
I recommend that you clean your jewellery once a week by gently brushing it with warm water and mild soap using a soft toothbrush, rinsing it generously and then drying it with a lint-free cloth. This cleaning requires a great deal of delicacy in order not to alter certain particularly fragile stones such as emeralds.
