To clean your jewellery is pretty easy to do yourself. If you leave your jewellery in a glass of lukewarm water with some dishwash liquid (no lime or lemon) and some ammonia for a night, you will see that everything looks so much better the next morning. You can then polish it with a soft toothbrush and rinse it afterwards thoroughly so all the soap disappears. Dry it with a soft cloth and if you can’t reach all   with a cloth then use a blow dryer so it really dries in the small spaces. You will be surprised how well your jewellery improves with such a cleaning ritual. Of course you are also welcome to visit us in our shop so we can do it for you. We can also clean it with an ultrasoon to cover all the hidden corners.


Yearly checkup:

We advise our clients to have their jewellery with diamonds and/or coloured stones checked up yearly. Jewellery is worn and just like clothes and shoes is subject to wear and tear. With all our daily routines jewellery will sometimes be hit or scratched or while being active we put some force on it. Gold  is a hard and a qualitative material but it is still possible to bent, scratch or dent it. That’s why it is good to have someone with a trained eye check on it to see if all is still good and to check if the prongs and/or the rim around the stone is still in a good shape. We would like to prevent that you lose the stone.



Diamonds and coloured stones have each their own properties. One of those properties is the hardness of the stone. The hardness can again be split up in scratch hardness and cutting resistance. The scratch hardness is measured in Mohs. All stones who score lower then 7 on the scale of Mohs are easy to scratch with a sharp utensil and therefore should be handled with care when wearing or when stored.

The cutting resistance has to do with the structure of the stones and cutters will take advantage of that. They will make use of certain flat planes (cleavage) and they know from which direction they will cut a stone. That means that from certain sides the stones are more fragile than other sides and that even when it is pretty resistant to scratches it still can crack if hit from a certain angle.
