A Guide to Gemstones

Gemstones have played various roles in the myths and legends of human cultures throughout history. Some tell a story or are believed to have special powers, but all of them share a common beauty. Each gemstone is unique with a special colour, birthplace and story. Gemstones come in every colour of the rainbow and are gathered from all corners of the world, with each coloured gemstone possessing a unique creation of beautiful colour. Some gemstones have been treasured since before history began and others were only discovered only recently. Regardless of your taste or budget, there is a precious stone for you.


Diamonds are the most popular and well known gemstone on the market today. It is an exceptional, naturally-occurring stone, which consists of pure carbon. Every carbon atom of a diamond is bounded by another four different carbon atoms and associated with well-built bonds. This plain, standardised, tightly-bonded series of atoms yields the hardest and most durable natural mineral.

Diamonds are captivating gemstones. They are extremely hard, making diamonds an appropriate cutting tool and for other purposes where hardness is necessary. However, Diamonds also contain some special visual properties such as an extremely high index of refraction, high dispersion and stunning white colour. All these properties and great marketing make the diamond the earth’s most famous gemstone.

Part of the explanation for diamonds fame is an outcome of its visual properties - or how it reflects with light. Several factors include fashion; tradition and marketing. Diamonds compose a high-lustre. This high-lustre is the effect of a diamond that reflects an elevated percentage of the light that strikes its surface, which provides the diamonds an enjoyable “sparkle”. Moreover, Diamond also consists of a high diffusion. As white light outdoes through a diamond, this dispersion makes that light to disconnect into its colours. Diffusion is what makes a prism divide white light into its certain colours. This property of diffusion is what provides the diamonds a colourful fire.

Formed in intense heat and pressure deep under the earth over millions of years, diamonds are the hardest known substance and one of the rarest gems on the planet. Traditionally used in engagement and wedding rings, a diamond is the ultimate symbol of commitment, strength and love.

Nothing quite says “value” like precious rarity. Sparsity is a commodity in the domain of gemstones and few things on earth are as rare as Tanzanite. Found in only one place in the world, it is known as the “gemstone of a generation”, with supply predicted to deplete in the next few decades. Combined with its natural brilliance and ancient roots, this stones exclusivity gives it inherent and unique value that is expected to increase markedly over time.

As reduced supply piques high demand, it is predicted that Tanzanite will attract significant ‘heritage’ appeal from collectors, investors and appreciators from around the globe. Today, owning Tanzanite is rarer than owning a diamond. Tomorrow it may be thought of as owning an extraordinary piece of history.

Originally unearthed in 1967, the formation of this stone 585 million years ago has been described as a geological phenomenon caused by extreme heat and unusual tectonic plate activity, making the probability of finding Tanzanite anywhere else on the planet, one in a million. Discovered by Masai tribesman in Tanzania, popular legends regard Tanzanite as a ‘gift from the Gods’ said to preserve youthfulness and improve vitality.

The elegant appeal of Tanzanite is not only in how it looks, but also in how it feels. Tanzanite has a reputation for being the most beautiful stone uncovered in the last 2,000 years. Depending on the angle from which it is viewed, Tanzanite’s kaleidoscopic magnificence is attributed to its impressive trichroic surface which reflects various shades of blue, violet and burgundy. Rated for their carat, colour, clarity and cut, the demand of Tanzanite amongst leading jewellery designers and other gem professionals for its clarity and potential for large cut stones, makes it a lucrative investment.

Moissanite is a gemstone born from the stars. It was first discovered in 1893 by a French scientist named Henri Moissan, who later won the Nobel Prize in Chemistry. He discovered microscopic particles of the gem that would eventually bear his name in Arizona, in a crater created by a meteorite that fell to Earth. He initially thought that he had discovered diamonds, but later determined that the crystals were composed of silicon carbide.

Natural moissanite is incredibly rare, so Moissanite available today is laboratory-created. After many years of trial and error, the particles Moissan discovered were successfully synthesised to produce what is now one of the world’s most scintillating gemstones. Moissanite is engineered to give the illusion of similarity to diamonds, but is compositionally and visually quite different from a real diamond. The durability, brilliance, and colour of the two gems are quite distinct.

There are many benefits to Moissanite. Moissanite is lab created with minimal environmental impact, making it eco-friendly. Cost per carat is lower than many other gemstones and Moissanite is a 9.25 on the Moh's scale, so their durability is suitable for everyday wear.
