Mimetolith is defined as a topographic feature on rock, Mineral specimen, loose stone etcetera
with any combination of shape and pattern that resembles a real tree, plant, animal, human etcetera. The stone shown in the pictures is a chert on which clearly seen an old lady's topography which is naturally formed.
"Yooperlite" is a trade name used to refer to fluorescent pebbles found along the beaches of Lake Superior in Michigan. These unique rocks are a type of syenite containing the mineral sodalite, which exhibits a distinct fluorescence when exposed to ultraviolet (UV) light.
The term "Yooperlite" pays homage to the residents of Michigan's Upper Peninsula, who are colloquially known as "Yoopers." Using a UV fluorescent light to illuminate these rocks reveals their captivating glow, making them a popular find among rockhounds and collectors.
Gemology is the study of gemstones, which
includes gem properties, locations, and origins. Gemology is often studied by
people in the jewelry business, including business owners, buyers, designers,
and appraisers. Others studying gemology include antique dealers. People in
these jobs need to be able to identify gems and gemstones and describe their properties.
A gemologist is someone who can identify the
gemstone with the help of Instruments.
What is mineral?
Mineral is defined as the substances which have
the following characteristics
Naturally occurring
Inorganic
Defined chemical composition
Orderly atomic structure.
What is Gemstone?
Gemstone is a natural, inorganic or organic substance
that has substantial beauty, rarity, and durability. Organic Gems: An organic
gem is one that was made by living things, present or past. Examples include
pearls, coral, jet, ivory, shell and amber. Inorganic Gems: Inorganic
gems are those which are created by geological process and (usually) dug from
the ground.
1.Beauty 2. Rarity 3.
Durability Beauty To be
considered a gem, a material must possess to a large degree this preliminary
qualification. Beauty in gemstone may depend on such qualities as color,
transparency, luster, brilliance, pattern, optical phenomena and, in some
cases, distinctive inclusions. Rarity This is a valued attribute of gems. It is is natural for man to esteem most
highly the things, which are hard to obtain, and this can come about if the
gemstone is simply unavailable in the marketplace, or genuinely scarce(limited
or short supply) in nature, even if it does not possess qualities above others
of similar beauty. A good example of this is taaffeite, which is not especially
attractive, (Usually a pale reddish-violet color like some spinels), but will
fetch (take) a very high price because of its rarity. Durability Durability depends upon on three factors 1. Hardness 2. Toughness 3. Stability 1) Hardness is the ability to resist
scratching. Commonly measured on the "Mohs" Scale of 1 - 10. Talc
lowest (1), diamond highest (10).
