Diamonds do need care to keep them at their brilliant best. A clean diamond not only reflects light better but actually looks bigger than one that’s been “dulled” by skin oils, soap, cosmetics and cooking grease. Diamonds have an affinity for grease and should be cleaned at least once every month to their fire at its brightest.

Commercial jewellery cleaner
Use the appropriate jewellery cleaner available from any reputable jeweller.

The detergent bath
Prepare a small bowl of warm suds with any mild liquid detergent. Brush pieces gently with a toothbrush while they are in the suds. Transfer to a wire strainer and rinse under warm running water. Pat dry with a soft, lintless cloth.

The cold water soak
Make a 50-50 solution of cold water and household ammonia in a cup. Soak the diamond for 30 minutes. Lift out and tap gently on the back and front of the mounting with a small brush. Swish in the solution once more, and drain on paper. No rinse is needed.


Let your diamond come in contact with chlorine bleach when you’re doing housework. It won’t damage the diamond, but it can pit or discolour the mounting.

Wear your diamond when you’re playing sports, doing rough work or doing the dishes. Even though a diamond is durable, it can be chipped by a hard blow along its grain.

Jumble your diamond pieces in a drawer or jewellery case, because diamonds can scratch each other and also scratch other jewellery.

Forget to take your diamond jewellery to a reputable jeweller at least once a year for a “check-up”. They will examine your jewellery for loose stones and signs of wear will usually give them a “shine-up” too.
