Crack Mark on Ruby Stone

by Nihar

There is fine crack mark on a ruby gemstone, it is a visible line that can be seen on the stone. Can you please tell me whether it's a good stone or not. If it's cracked, will it bring misfortune?

Hi Nihar,

The answer to your question will depend on the severity of the crack and if the ruby has any additional cracks in the inside of the stone (known as inclusions).

Rubies are extremely hard gemstones, with a 9.0 Mohs hardness rating, and they can generally hold up well even if they have small cracks on the outside. However, if the crack is deep or if the ruby also has inner cracks then you may not want to use this stone in a piece of jewelry and particularly not for a wedding ring.

Outside and inside cracks can affect the stability of the stone – and if the stone is exposed to a hard knock or blow the cracks can either grow or – in a worst case scenario – the stone could break.

If the crack is very minor, you may either have the gemstone set in a protected setting by a professional jeweler – or you might want to consider paying to have the gemstone professionally enhanced with a fill material (like lead glass) to smooth the surface and reduce the outside crack – although a fill enhancement will increase the stability of the stone and decrease the visibility of the crack it will also dramatically lower the overall value of the ruby.

Either way, if you decide to wear the gemstone do not expose the stone to any hard knocks or blows and do not use an ultrasonic cleaner to clean the gemstone.

Will the crack bring misfortune? I don’t believe so. The ruby is believed to be a stone of passion, guidance, knowledge and decisions – but the gemstone is not specifically believed to bring about fortune.

If you are thinking about purchasing the gemstone, use caution. Any visible cracks will affect the value of the ruby, even fine ones, in addition to the stability of the ruby. But if the ruby is priced well, the crack is small and no cracks are inside the ruby, then it could be a good purchase - especially if you are fond of ruby gemstones.

I hope this info helps. If at all possible, take the ruby to a trusted jeweler in your area – and seek the professional opinion of the jeweler as to the severity of the crack and if the crack will affect the ruby’s stability, also how much of the ruby's value is affected by the crack.

Remedy for Cracked Ruby Gemstone
by: Anonymous

If there is a small crack which occurred after hitting a ruby, what precautions should be taken to keep the crack from growing or splitting the gemstone?

- If a crack developed after the ruby experienced a hard blow, it is a good idea to have the ruby assessed by a certified gemologist. The gemologist can analyze the depth and severity of the crack and identify if the crack poses risks to the ruby's stability.

Until you can have the ruby assessed, avoid cleaning the ruby in an ultrasonic cleaner - and definitely try not to wear the ruby at any time when the ruby could be damaged again. Likewise, if the ruby is set in white gold avoid re-rhodium plating the jewelry as the plating process can further damage gemstones that have cracks or fissures.

Ideally, it is best to avoid wearing the ruby until a gemologist can analyze the crack and see how much of a danger it poses to the ruby's structure.

It may be possible to repair or at least stabilize the ruby, depending on the severity of the crack. Setting the ruby in a protective setting too can help to stabilize the gem enough so that it can be worn without worry.

What is the Ruby has a pit on its surface?

What if the Ruby has a pit on its surface?... No cracks just a small pit.. Does that lower the value of the gem too?


Yes, pits on a gemstone will lower the value of the gemstone regardless of the type of gemstone. Any blemishes will lower the value - whether on the outside or inside.
