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.
when it is dry and hot the air acts as denser medium,when its a wet day the air around act as rarer medium.........sound travels faster in rarer medium than denser medium
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.
Orangutans are the rarest due to their home being cut down for wood or poachers are hunting them down for their fur or the cage up and sell to the highest bidder so the can earn money

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.

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.
If the light travels faster in the second medium, then this medium is called the rarer medium.
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.
That would depend greatly on your idea of expensive. They are not as expensive as higher quality and rarer stones like diamonds and emeralds. Typically, cubic zirconias are a less expensive choice than diamonds and are sustituted for such.
No. Pink diamonds are little more but they are both more expensive then colorless diamonds.
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.
