Learning about diamonds and Tanzanite at The Diamond Works

Prior to The Diamond Works experience, my knowledge of diamonds and Tanzanite was limited to Marilyn Monroe quotes and the location of mines in South Africa. Whilst the famous quote may be true, “diamonds are a girl’s best friend”, what else constitutes to these rare gems? Today, I am speaking about my recent visit to The Diamond Works in Cape Town and sharing a few tips when investing in these gems.

The Diamond Works Tour

A complimentary glass of MCC awaits as you enter The Diamond Works. Aimee Lentz, the brand manager eagerly awaits to take us on the tour. She well versed on the subject of diamonds and Tanzanite. I’ve visited a few jewelry stores, but this one is different, the environment and staff are not intimidating. You feel welcomed from the time you enter, it is evident that the staff are proud ambassadors for the brand. Tourists and locals are flocking in, each with a glass of MCC in hand, eagerly wanting to learn about these sought-after collector pieces which capture the heart of Africa. The tour lasts for approximately 20 minutes and teaches you valuable information about diamonds and Tanzanite.

Skilled craftsmanship at The Diamond Works

The first part of the tour focuses on the art of diamond cutting and craftsmanship. According to Aimee, it takes 10 years of apprenticeship and expertise before the diamond cutter is allowed to cut or polish a rough diamond. The tour follows with the making of diamond jewelry (cleaning, bruting and polishing) and the unique history of diamonds in South Africa. After all the information seeps in, you develop a deep appreciation for diamonds as there are many years of skill, artistic vision, dedication and complexity that goes into creating these timeless pieces.

In 1967, on the foothills on the magnificent Kilimanjaro, the most Eastern reaches of Africa, Tanzania, the indigenous Massai tribe uncovered the rare gem –tanzanite. The only tanzanite mine in the world. Compounded by its exceptional rarity, tanzanite’s exclusively African heritage and the alluring narrative of its discovery have proved to be a precious heirloom with love from the African continent. Resembling colours that waft over the Indian Ocean, tanzanite is uniquely trichroic, radiating three different colours from blue, violet hues and burgundy.

According to Aimee, Tanzanite is 1000 times rarer than diamonds. Tanzanite is noted for its remarkably strong trichroism; appearing alternately sapphire blue, violet and burgundy depending on crystal orientation. If you’re thinking of investing in Tanzanite, it is graded by means of colour, clarity, and cut. Here 3 things to consider before investing in Tanzanite.

Tanzanite Grading System

Colour – Tanzanite is considered to have the finest hues of blue. The gem is strongly trichroic, meaning that it displays three colours, namely blue, violet and red. Good quality Tanzanite has a deep royal blue or violet colour. The more intense the colour, the better the quality.

Clarity –  Tanzanite is graded in a similar manner to diamonds, they range between Internally Flawless IF (most sought-after and higher in value) to Included (1-3).

Cut – It is very important for a Tanzanite to be well cut, as it impacts not only on the brilliance and fire of the stone but also on the overall quality. If the cut is too shallow, the light will escape from the stone and will result in a lighter shade of violet or blue.

I enjoyed The Diamond Works tour as the sales representatives do not punt sales or force you to purchase anything. Their mission is to educate tourists and locals about these rare gems. You leave with more knowledge around the subject in order to make better decisions when you are ready to invest. The Diamonds Works branch is located in Lower Long street (opposite the CTICC) and trades every day from 9h00 – 19h30. The tour is completely free of charge.

    Very interesting article! I have driven past this store often (years actually) and didn’t know that they offer such an informatory tour. I didn’t realize the history or value of tanzanite. Actually considered it a cheap stone. But now I know better. The fact that it’s exclusively from SA makes me even happier!!

    • I didn’t know much about Tanzanite and diamonds prior to the visit either. Not that I consider myself an expert now, but I know what to look out for and the type of questions I need to ask before investing. I would highly recommend the tour to anyone wanting to invest in diamonds/Tanzanite, as it gives you a basic understanding of the 4 C’s and what to look out for when investing in these timeless pieces.
