Yes, this indeed is a question because the less you touch your diamonds the better it is for them. Do you know that every time you touch your diamonds, oil from your skin is transferred to the stone? Over time, this builds up a film on the stone and makes it appear dirty. You don’t want your favourite piece of diamond jewellery to lose its sheen, do you? So, don’t touch it every now and then.
Diamond rings or bangles should also not be worn when applying hairspray, creams or lotions. This can temporarily discolour the diamonds and make them lose their lustre. It is important to note that while diamonds repel water, oils and grease can easily stick to diamonds. This holds true for cut and uncut diamonds.
