Frequently Asked Questions

Your guide to fine jewellery, tanzanite and diamonds.

At Tanzanites & Diamonds of Hermanus, we love helping our customers discover beautiful jewellery and understand what makes each precious metal and gemstone so special.

We often get asked questions about white gold, platinum, rhodium plating, tanzanites and diamonds. So, we've put together a few answers to help you make an informed choice when selecting your next special piece of jewellery.

1. What is the difference between white gold and platinum?

White Gold

White gold is made by combining pure gold with other white-coloured metals to create a beautiful, durable alloy. It is usually coated with rhodium to give it a bright, brilliant white finish.

Platinum

Platinum is a naturally white precious metal. It is denser and heavier than gold and does not need rhodium plating to maintain its naturally white appearance. It is also highly durable and an excellent choice for everyday jewellery.

Which one should you choose?

Both are beautiful choices! White gold offers a luxurious look, often at a more affordable price, while platinum is a naturally white, premium precious metal. Your choice will depend on your budget, lifestyle and personal preference.

2. Why must white gold be rhodium plated?

White gold is naturally slightly yellowish because it contains pure yellow gold mixed with other metals.

Rhodium is a precious metal from the platinum family. It is applied as a thin coating over white gold to give jewellery its beautiful, bright, silvery-white shine.

Why is rhodium plating important?

• It gives white gold a brilliant, bright white finish.
• It enhances the overall appearance of your jewellery.
• It provides a protective surface layer.
• It helps your diamonds stand out beautifully.

Over time, everyday wear can cause the rhodium coating to wear away, particularly on rings. This is completely normal. Your jewellery can simply be professionally rhodium plated again to restore its original sparkle.

4. What makes Tanzanite so special?

Tanzanite is one of the world's most fascinating gemstones.

Found in only one known commercial mining area near Mount Kilimanjaro in Tanzania, this beautiful gemstone is extremely rare.

Its captivating blue and violet colours make it a favourite among jewellery lovers around the world.

One of the most special characteristics of tanzanite is its pleochroism, meaning it can display different colours depending on the angle from which it is viewed.

Tanzanite is a wonderful choice for someone who wants something unique, colourful and truly special.

5. What should I look for when buying a diamond?

When choosing a diamond, it is important to understand the famous 4 Cs:

• Cut: Determines how beautifully the diamond reflects light and sparkles.
• Colour: Measures how colourless the diamond is.
• Clarity: Refers to the natural inclusions and imperfections within the diamond.
• Carat: Refers to the weight of the diamond.

All four characteristics influence a diamond's beauty and value. The perfect diamond is ultimately the one that you fall in love with!
