Left to right: Orange Juice, white vinegar, red wine and lemon juice.
Let's see if there's any difference in opals after soaking for one hour.
After one hour, has opal showed any change ?
Take it out one by one,,,
Into a tap water for about 5min.
Dry them with a tissue and let's see...
Left : Before / Right : After
Opal into Lemon juice
Weight : 1.51ct
Left : Before / Right : After
Opal into Orange Juice
Weight : 1.23ct
Left : Before / Right : After
Opal into Vinegar
Weight : 0.83ct
Left : Before / Right : After
Opal into Wine
Weight : 1.23ct
Nothing's changed after a short time of period. So you don't have to be panicked at the restaurant even when you spilled a 'Lemon juice' or a 'Red Wine', etc...
But we'll continue on our experiment just in case.
