Crescent Vert jewels possess first-class quality
Crescent Vert jewels are not imitation gemstones. In order to provide the true joy of wearing beautiful jewels of rich color, Kyocera, with its high technology, crystallizes Crescent Vert gems in the ideal environment through careful quality control. Therefore the jewels we manufacture have only minimal impurities, and thus possess the finest color and transparency the likes of which are rarely found in natural gemstones. Moreover, we select only the finest gems and only the best of the best are used for our finished jewels. Only a small percentage can be named and sold as Crescent Vert. Chemically, physically and optically, Crescent Vert are the same as natural jewels.
Kyocera’s Crescent Vert is available in varieties such as emerald, ruby, padparadscha sapphire, alexandrite, sapphire and opal. Opal is not “crystal” but is actually amorphous, and so we call them “Created Opal.” As for other products, we also sell natural jewels.
Making of Crescent Vert
Making of Crescent Vert Emerald
We purify the crude beryl ore and process it into the most suitable state for a jewel.
We purify beryls which are formed with the same elements as natural Emerald (beryllia, alumina and silicic acid). However natural emerald has inferior crystal formation and transparency.
We grain crude beryl ore.
We put grained beryl into a melting pot and heat it to 1,410 degrees Celsius. This reproduces the same state as magma inside of the earth, and thus dissolves the beryl.
A small piece of emerald is put into the pot for the nucleus of the crystal.
By gradually lowering the temperature over a long period of time, the emerald crystal grows.
The crystal gradually grows around the nucleus. Then the emerald crystal with a hexagon pillar, roughly the size of a thumb, is formed.
Experts polish the gems one by one carefully by hand, and only then is a first-class brilliance born.
Making of Created Opal
We put spherical silica (silicon dioxide) into a liquid tank in order to form opal.
Many balls of silica (silicon dioxide) are dispersed. From a distance they appear white in color; however, individually they are actually transparent. Natural opal is also formed by balls of the silica in underground water.
After silica sinks and piles up neatly, it start shining.
Opal can shine in various colors only when balls of silica are piled neatly without gaps.
Silica completely sinks into the bottom.
The \"Created Opal\" is produced through careful handling over a long period of time.
Completed Created Opal
Hardened opal after heating and drying. Natural opal is also heated and dried and hardened in the natural environment.
Created opal's loose stone
Because it has a more stable structure than natural opal, it can be more easily cut and thus used for bold designs.
Just as earth does, Kyocera creates jewels with love.
\"The appeal of jewels is their ability to provide hope and to enliven people's spirits.” Based on this view, we reproduce jewels on behalf of the earth. Our aim is not to produce fakes, but to reproduce the most beautiful colors of jewels possible. We have been manufacturing jewels with unswerving passion and we will strive to continue to develop technology and enliven people’s spirits.
