Benefits and features of semi precious
gemstones
Many people buy gems by type - for example, they want to buy a natural smoky
quartz, a tourmaline or an amethyst. But something we have learned in the gemstone
business is that most customers are primarily concerned with colour and less
interested in the variety of gems. Since colour is actually the most important factor for
most people when it comes to buying loose gemstones, it only makes sense to start
your search by buying precious stones by colour.
Semi precious stones
The semi precious gemstones have a very different value among them and it is much
easier to get semiprecious stones of great size and purity (clean) than precious stones
of such characteristics.
The oscillation of its value or cost will depend on the same conditions that influence
the precious stones: hardness, rarity and beauty and perfection. There are
approximately 130 mineral species catalogued as semiprecious, in addition to amber,
which is a fossilized vegetable resin.
Finding rainbow moonstone by colour can often be difficult, since web pages tend to
organize their inventory by variety of gems instead of colours. So for those who want
to know what their options will be in particular colours, here is a list of types of gems
organized by colour.
Since there are hundreds of colour variations in colour gems, we have organized this
list based on "base" colours or families of colours. This means that an orange-red gem
can enter the category "orange" or "red" and a green-blue stone would be in the
category "green" or "blue".
Red gems
Red gemstones are actually quite rare and are found mainly in ruby gemstone,
spineland garnet.
Pink gems
The most famous pink gemstones are tourmaline and spinel. Pink sapphire is
charming but rare, especially in gems weighing more than 1 carat. Garnet rhodolite
tends to be pinkish-purple.
Blue gems
The classic blue gemstone is sapphire. Intense saturated blue is also found in spinel
and kyanite. There are many choices in the lighter blues, including pink topaz, zircon
and aquamarine. The Tanzanite and iolite have a more violet blue tone, while the
tourmaline Paraiba, the apatite and fluorite tend to have a blue-green colour.
Green gems
The peridot, which tends to be olive green, has become an important jewellery
gemstone.
Yellow / golden gems
Citrine is the most common golden-yellow gem, but yellow sapphire is most sought
after. There are also good choices in tougher gems such as beryl and chrysoberyl.
Canary yellow tourmaline from Malawi is very rare.
Violet / purple gems
The amethyst is the classic example, though fluorite can also be found in a similar
shade of purple amethyst. There are wonderful violet tones in the spinel, the
tourmaline and the sapphire. Chalcedony is often found in a unique lavender tone.
Orange gems
The espesartite garnet is the most famous orange gem but there are also several
options. The orange sapphire is produced by heat treatment, while the finest fire opal
is in orange-yellow to orange-red tones.
White gems
This category includes both colorless gems, such as diamond, sapphire, zircon and
topaz, as well as precious white stones such as opal and moonstone.
