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

Alexandrite: The World's Most Magical Colour-Changing Gem. In short: 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 of all; in the jewellery trade, you will find almost exclusively synthetically produced or colour-changing alternatives such as zultanite. For everyday wear, the difference is mainly one of price; visually, good synthetics are almost impossible to distinguish.

Natural vs Lab-Created Alexandrite

Alexandrite Quality Factors

If a piece is meant to mean something, what matters most is that it is worn and not left in a drawer. The stainless steel charm bracelet can be added to over the years, the 32 to 36 cm pendant necklace holds a pendant directly around the neck, and the small hoop earrings work without the question of size. Everything is made of stainless steel, so they are also fine for showering and exercising.

Which chain length sits where?

What do you get in which price range?

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

What goes with jewellery pieces?

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

What is frequently asked about this

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 around the neck and add two centimetres.

How do I combine two chains without them getting tangled?

Yes. The important thing is the distance: if the difference is less than five centimetres, the chains will get tangled during the day and the layered effect will be lost.

How do I clean a sticking clasp?

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

Can I combine several orders?

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