Let me introduce myself.
My name is Rene, I’m a Sapphire trader and jewelry designer.
I buy rough material, cut, make jewelry and sell loose and jewelry sapphires all over the world.
I’m a gemologist and expert on sapphires and jewelry.

Now to the issue of cleaning sapphire.
Sapphire is Hard (second only to diamond) you can not do any damage in any cleaning method!

After we finish the ring the goldsmith will run it in an industrial ultra sonic to check that the tiny diamonds are not falling (we don’t even check for a damage to the stone).
During the cutting or heating process we clean the sapphire with the strongest industrial acids.
We polish the gold prongs of the ring after the sapphire is mounted and no damage is done to the stone from the metal file touching the stone in the process .
The only way I know of scratching a sapphire is using a diamond.
Sapphire can be broken (as diamond) but no cleaning method can scratch it.
Don’t use ultra sonic if the jewelry is inlaid with small sapphires or diamond as they can fall
But you can use any method that will not damage the gold,
You just can’t damage a sapphire by cleaning it!!

@AllSapphires:  This is very interesting to say the least.  I was just going by what 2 jewelery designers have told me in the past about sapphires.  I was even told when designing with sapphires the designer should not hold the flame on the stone itself for long because it will cause damage.  I can only go by what others say – so – when I hear new information I always find it interesting.

Blow heating (low temperature traditional heating) is done in 1000 Celsius degree to prevent any damage to the internal of the sapphire. The procedure takes many hours.

Regular heating of sapphire is done in 1600-1800 Celsius degree and in most cases will not damage the sapphire. It takes from 8 hours to one month!

The jewelers are working with low temp fire to bend the gold in a temperature not even close to low temperature heating of sapphire 1000 Celsius degree.

The gold in the jewel will melt long before you can make any dammage to the sapphire.


My conclusion, those designers never worked with sapphire!

They are probably referring to Tanzanite, a blue soft gemstone and a real nightmare for jewelers trying to repair a jewel with it.

I looooove  my stone

I have emerald and trillion cutsides which are least reflective overall but it gives of a steely mirror effect

It does sparkle, I have a cushion diamond and to compare the diamond is like a disco ball and the Sapphire is like the sparkles u see on top of the ocean from the sun  is clearer and cleaner looking but so beautiful

No don’t wish I had color,  I do pair it with a ruby/diamond band and the diamonds look yellow in comparison. 

I clean with warm/hot soapy water

I’m anal abt cleaning it but I’m like that with all my rings

I think it would be gorgeous in rose gold.
