There are various possible answers, as "rockhoundese", the language of mineral collectors, comes and goes, and varies by country. Some possibilities are:
- killer
- top shelf
- choice
- grade A
- real humdinger
- sick
- display quality
There are no doubt others.
People commonly refer to the mineral halite (NaCl = sodium chloride) as rock salt. Rock salt is formed by the continuous evaporation of sea water. In the sequence of minerals precipitating out of the water halite comes after gypsum and anhydrite (calcium sulphate minerals) and before the rarer types of chlorides like potassium chloride.
Yes, onyx is much more expensive than marble. This is because onyx is considered to be a much softer stone than other stones.
All the elements found on Earth and in the whole cosmos can be found in stars. However the rarer elements like Gold are only created in stars up to 10 times the size of our Sun in a supernova explosion. The energy released in a supernova is massive resulting in very high temperatures. These temperatures create the conditions for these elements to be formed. As a result of this the elements made in a supernova are very rare. That's why on earth Gold is very expensive as it is in demand as there isn't much of it compared to other elements.
Yes, platinum is considered a rare metal. It is rarer than gold and is often found in small quantities combined with other metals such as nickel and copper. Its rarity contributes to its high value and use in various industries.
The value of agates can vary greatly depending on factors like size, quality, and color. In general, the price of agates can range from a few dollars per pound for common varieties to hundreds of dollars per pound for rarer and more valuable specimens.
Most carbonate minerals are either calcium carbonate (limestone) or a mixture of calcium carbonate with magnesium carbonate (dolomite). However other metals can also combine with carbonate to produce much rarer carbonate minerals.
A R. Powell has written: 'The analysis of minerals and ores of the rarer elements'
Carbon.
It's prettier and rarer.
Platinum is a rarer element on the earth.
Both are considered expensive, but a diamond is more expensive simply because it's a harder mineral.
No, it does not. A magnet produces a magnetic field, which attracts only ferromagnetic materials, such as iron, and also repels other magnets. Other ferromagnetic materials include: cobalt, nickel, iron, some alloys of rarer earth metals as well as natural minerals, such as lodestone.
Quartz is more common than emeralds. Quartz is one of the most abundant minerals on Earth, found in a variety of locations across the globe. Emeralds, on the other hand, are much rarer and tend to be found in select regions with specific geological conditions conducive to their formation.
Normal types wouldn't be. but leopard geckos come in different morphs, or colors. Nicer and rarer colors will cost much more. A normal looking gecko can cost $25, while a rarer coloration could cost $3000.
Buy a BMX frameset and put your own selection of components on it.Switch parts out for rarer, more expensive parts, have it repainted.
No. Diamonds are formed deep within the Earth's mantle, under extreme high temperature and high pressure. They erupt to the Earth's surface by way of deep source volcanic eruptions,which leave behind plugs of solidified magma called volcanic pipes, which may contain pieces of minerals they gathered on their way up, including diamonds. These events are much rarer than ordinary volcanic eruptions, in fact we have yet to observe one in action.
There are lots of sorts. The most common (because of its cheap price tag) is chronic, but there are rarer and more expensive types for example: blue cheese and blueberry.
