Alexandrite: The World's Most Magical Color-Changing Gem

Alexandrite: The World's Most Magical Colour-Changing Gem. In a nutshell: Alexandrite is a chrysoberyl that changes colour depending on the light source: greenish in daylight, reddish in artificial light. Natural stones are among the rarest and most expensive coloured gemstones in existence; in the jewellery trade, you will find almost exclusively synthetically produced or colour-changing alternatives such as Zultanite. For everyday use, the difference is primarily a matter of price; visually, high-quality synthetics are hard to distinguish.

Alexandrite Quality Factors

If a piece is to mean something, what matters most is that it is worn and not left in a drawer. The stainless steel charm bracelet from €38.95 can be added to over the years, the pendant chain in 32 to 36 cm from €33.95 wears a pendant right at the throat, and the small hoop earrings from €29.95 work with them without any sizing questions. Everything is made of stainless steel, so it is also problem-free when showering or exercising.

Overview of all necklaces

Which chain length sits where?

What do you get in which price range?

Beyond a certain point, you are no longer paying for durability with jewellery, but for the brand and packaging. A piece for twenty-five euros that you wear two hundred times is cheaper than one for ten euros left in a drawer. Those looking for substance that lasts for decades end up with solid gold and a different price level.

What goes with jewellery?

The principle is simple: one dominant piece, the rest takes a back seat. Gold with gold and silver with silver is the safe foundation; mixing is done via a piece that contains both tones. In the end, what counts is whether you feel comfortable with it; everything else is just a guideline.

Frequently asked questions

How do I find the right chain length?

Without further information, 45 cm is the most reliable length. It sits at the collarbone and looks neither tight nor long. If you want to be precise, measure your neck and add two centimetres.

How do I combine two chains without them tangling?

Yes. The distance is important: with a difference of less than five centimetres, the chains will tangle during the day and the layered effect is lost.

How do I clean a sticking clasp?

The clasp is rarely defective, usually just sticky. Warm water with dish soap and a soft brush are sufficient.

Can I combine multiple orders?

It makes sense to combine all desired parts into one order. From two items, the volume discount of 20 percent applies, and shipping is free from 59 euros. Two separate orders lose both benefits.
