All about gemstones

Where do precious and semi-precious stones come from ?

They can be found everywhere on the globe.

Some are discovered on their original site, ie where they were formed, while others are a little further away, transported by elements such as wind, water or lava.

Choose the opal of your jewelry : rings, bracelets and pendants

Opal is a fascinating stone, but of all precious stones, is certainly the most difficult to choose to be mounted on a jewel.

It's indeed complicated to give a physical description of the opals as they vary in color, transparency and reflections depending on the country of origin and often same, vary greatly depending on the extraction mine.

Unlike a ruby or a diamond for which it's easy to compare prices according to some criteria (the famous 4Cs of diamond), all opal stones are unique in their colors and light effects.
