Leave it too long between cleaning and this film can accumulate, blocking the reflection of light and stopping your diamonds from looking their mind-blowing best.
So regular cleaning is key to retaining that Montluc sparkle. And while diamonds are the hardest substance known to man, you need to take care.

Avoid detergents and cleaning agents which leave a soapy scum. They can also contain harsh chemicals and abrasives that not only affect the diamond but also the gold setting.

Avoid vigorous cleaning, which can dislodge a diamond if dirt has built up. A loose diamond can scratch, erode and wear the surrounding gold – not to mention the fact it can fall out…

Avoid ultrasonic cleaners, which can leave your diamond a little the worse for wear.

Oh yes – and avoid old school secrets like toothpaste, baking soda and old toothbrushes. Toothpaste is an abrasive and can leave scratches. Old toothbrushes can dislodge diamonds.

We’ve even heard of people using gin or vodka. Well, yes… that can work. We suggest pouring a generous measure into a glass. Adding two ice cubes and a slice of lemon or lime. The mixer of your choice. And enjoy. Now it’s time to get to work…

Now here’s how to actually clean your Montluc diamond jewellery

1. Mix one part washing up liquid (yes, really) with three parts very warm water.

2. Let it soak 20 to 40 minutes – or overnight if particularly dirty.

3. Gently brush the stone with a soft toothbrush.

4. Rinse under warm running water and dry with a soft lint free cloth.

5. Repeat if required.

You can use a dental water pik to flush away small bits of grime, or a wooden toothpick to very carefully push away any lingering dirt.

If any scratches remain or your diamond still looks a little dull, you haven’t done anything wrong. It just needs a professional polish.

Check for loose diamonds

As we’ve mentioned, a loose diamond can not only damage the gold setting but may also end up falling out altogether. So it’s well worth checking to make sure once you’ve cleaned your jewellery. Remove the tip from a cotton and use it to gently nudge the diamond. If it appears to move, try to get it checked as soon as you can.

How should I store my diamond jewellery?

Whether or not you wear your diamond jewellery on a regular basis (although let’s face it, it’s there to be admired) you should always keep it separate. Diamonds are the hardest gemstones on earth, but despite popular theory they can still be scratched by other diamonds. We suggest you store your jewellery in the original box, a soft pouch, or a custom-designed jewellery box.
