Is a Gem a Stone?

As a stone of value, a gem is cut and polished to serve as ornaments in jewellery, among others, and is usually made of minerals. Many gemstones are minerals with a unique crystal structure. These gemstones can be formed when minerals, under heat and pressure, are fused together through movement of tectonic plates. Gems are mineral crystal pieces that are cut to assume a shape that will suit the intended jewellery piece. Gemstones can be transparent, opaque or translucent.

The value of gems is based on rarity, and to qualify as a gem, the stone has to have beautiful clarity and hardness than can resist scratching. Gems can come in different colours such as blue, pink, purple, yellow, and orange, that are often the bases for gemstones names, and can even come with crystals meanings.

A List of Rare Gemstones For Sale

  • Alexandrite – This June birthstone is exceedingly rare, which is why you won’t see natural Alexandrite very often in a piece of jewellery. Its true color will vary depending on its origin, but the most desirable colour change is when in incandescent light it changes to red, violet/red or purple/violet from green, teal bluish green, or olive green.
  • Aquamarine– As its name implies, this gemstone reminds you of seawater. With sea green to sky blue tones, this is the birthstone for March. Albeit better known for its light watery tones, its finest colour is deep blue.
  • Beryl– This gemstone takes its name from the Greek word; ‘beryllos’, which means “precious blue-green colour-of-sea-water stone”. Beryl can come in pale shades of yellow, green and pink and even in raspberry orange. Aquamarine, Emerald and Morganite are popular varieties of this stone.
  • Emerald – This is the birthstone for those born in May, and is also used in gifts by those celebrating their wedding anniversaries for the 20th and 35th time. Emeralds can come in different shades of green, with blue and yellow hues, but the rarest and most sought after colour is deep green.
  • Garnet – The birthstone of January, its namesake is derived from the Latin word for ‘grain’ due to its rounded crystals, which also reminds you of a pomegranate’s red kernels. Garnet has a beautiful glassy lustre and is usually thought to have red or wine red colour. A red garnet with a tinge of purple and a reddish brown hue are also commonly seen. Garnet can also come in some shades of orange and many other colours including rare colour-change material.
