Why buy a Diamond?

Diamonds to express wealth - and magic

This marvel of a shiny stone dazzles people since its discovery around 400 BC. It captured men and women alike with its magnificent glow and inexplicable magical properties. It has also been confirmed that it is the most robust material ever known to man.

Kings and queens used diamonds to adorn their crowns. That's why people of all nations and classes could not wait to get their hands on this precious stone. Unlike other materials, the diamond does not seem to lose its value, brilliance and overall greatness. People around the world dream of having at least one piece of diamond jewelry. This gem just seems to have that something—a sprinkle of magic if you will. It simply makes you feel wonderful.

Diamonds as an investment

Buying a diamond is a considerably big investment. Like all investments, there are a few factors to take into account before diving into. Diamonds come in different shapes and sizes but also in different colors. We speak about the 4 C's of diamond valuation: carat, color, clarity and cut. These four determine a diamond's value.


According to popular belief, different diamonds have different meanings. You can choose from deep to light red (like a pink hue) that denotes passion and commitment. Or you can choose a more royal approach and gift someone with a deep blue stone. There many options out there when it comes to its design too. You can choose from tear shaped diamonds, a traditional round one, or a square cut diamond. The sky is the limit.


Some people buy a diamond as an investment. They realize a diamond lasts a lifetime. It is not a piece of clothing or even a car that can be replaced easily. Each and every piece of diamond is unique. If you already splurge your money on various things, do not opt out of making this once-in-a-lifetime investment, simply because it is a bit more expensive than all the other options.

Diamonds for your loved one

The wedding proposal and marriage are a huge deal. Buying a diamond engagement ring adds beauty to that special moment. Diamonds are the true symbol of love, commitment and “durability”, which marriage definitely requires.

Overall, there is definitely something inexplicably magical about this gem. It seems like it continues to capture hearts throughout the ages. Additionally, it seems like they are not just girls’ best friend… Kings and queens used it in ancient times, actors and actresses love to show off their bling on the red carpet. But also stay-at-home moms appreciate that little stone and cannot wait to put them on for a special night out. There are many reasons to buy a diamond. If you can afford it, go ahead and get one, you will not regret it. Our diamond consultants are standing by and gladly help you to find your perfect piece.
