Every man does not wear bracelets
Versatile to suit different tastes of women of all classes and age groups, bracelets are made by the traditional craftsmen, who have inherited craftsmanship from their previous generations, making each bracelet, exquisite and unique. However once the charms were on the charm bracelet the style would be fixed and only large upheaval and cost would alter the style of the bracelet. Every man does not wear bracelets.
That type of Jewellery has not quite caught the fancy of men. There will not be many men out there sporting a bracelet on either their wrist or their ankle. Sometimes, a man can get away with a bracelet if it has the name of his wife or children on it.
Gemstones are so durable
A few are mineraloids not true minerals and are including here: opal, amber, and moldavite. Foremost is durability - it must not easily corrode away, nor can it be brittle. It is so durable that nearly all of the gold ever mined is still in circulation or storage. In some cases, the names are true misnomers, such as Green Amethyst for prasiolite-a transparent green variety of quartz.
In most cases, these variety names are historical, as the gemstones were not recognized as being varieties of other minerals until well after the name was in common use such as aquamarine, emerald, and heliodor as varieties of beryl. And that is related to the third characteristic, ductility. You can see the options are endless and when you are commissioning a piece, why compromise a thing when you can choose!
The color is the greatest difference in the metals
The color is the greatest difference in the metals. The elements which include over one hundred known minerals are a diverse class when taken as a whole. The non metals are extremely diverse. Due to the diversity of the non metals subclass there is most of this diversity.
The non-metals include some elements known as semi-metals who share some properties with metals but differ in other characteristics. The hardest mineral known to man is from this subclass, as well as one of the softest. The Metals Subclass and related metal alloys contains metals whose properties are rather similar due to the common way in which they crystallize and bond.
