What are gems and precious metals?
The three precious metals used most often in jewelry are gold, platinum and silver as they share the qualities of allure, workability durability and rarity. Gemstones and metals are essential to Kaina Jewels and each gemstone has been handpicked from different parts of the world to create a Kaina original.
Are gemstones metals?
Many gems are produced from metallic minerals containing elemental metals as the main part of their chemistry. These gems contain elemental metals such as copper, cobalt, iron, lead, nickel, platinum, titanium and zinc. Others, such as gold and silver, are native elements.
What metals are common to these gemstones?
The most common trace elements in gemstones are beryllium (emerald), chromium (emerald, jade, chrome tourmaline, ruby and topaz), copper (Paraiba tourmaline, turquoise and malachite), iron (yellow sapphire, aquamarine, green tourmaline, chrysoberyl, citrine and jade), lithium (green and pink tourmaline), manganese ( …
How are gems and minerals related?
A mineral is an inorganic, naturally occurring substance with distinct chemistry and crystalline structure. Gemstones are materials that have an economic or aesthetic value. Therefore, not all gemstones are minerals. For example, amber is solidified tree resin, so it is not a mineral.
Are rubies rarer than diamonds?
“Many colored gemstones are much more valuable than a diamond, but it all depends on the quality of course.

Musgravite was discovered in 1967 and is arguably the rarest gemstone in the world. It was first discovered in Musgrave Ranges, Australia, and later found in Madagascar and Greenland.
How are precious metals and gemstones alike and different?
They have a characteristic chemical and physical properties and usually a regular crystal structure. Most rocks that we see today are made of minerals (they are the ‘ingredients’ in rocks) and both precious metals and gems are subsets of minerals. There are over 3,000 known minerals. Some of the most common ones and their uses are:

Why do some gemstones have an intense colour?
The transition metals may be part of the chemical formula of the mineral, or they may be present in the mineral as impurities. Even small amounts of these transition metal impurities, where a transition metal atom sits in the place of another atom which would usually occupy that position in the structure, can lead to an intense colouration.
Why are precious metals important to the economy?
Precious metals are rare, naturally occurring metallic chemical elements of high economic value. Chemically, they tend to be less reactive than most elements. They are usually ductile and have a high lustre. In history precious metals were important as currency but are now regarded mainly as investment and industrial commodities.
