I am not trying to bash nor insult Indonesian gem dealer, but you have to be very very cautious if you went shopping for gem in Indonesia. I have visited a lot of public gem market, and I know most of them are trying to sell undisclosed treated gem. However, Indonesians' gem market brought it to a whole new level!!! Here's the story:
I was on business trip in Indonesia when one of my Indonesian colleague knew that I was looking for a black opal. He claimed that Indonesia has the best opal in the world. So, he took me to a gem market in Jakarta called Jakarta Gems Center. My first impression was this market is the most crowded gem market I have visited so far. I skim through several dealers and saw a lot of dyed chalcedony which were common phenomenon in every gem market. Then, my friend started asking if any dealers have an Indonesian black opal. All dealers said they only had african opal (I bet they meant ethiopian opal). Since we could not find any indonesian black opal, we started visiting the higher end dealers. This was when things got complicated.
The first dealer (an english speaking arabs):
he sold a lot of higher end gem like sapphire, spinel, etc. He showed me several big indonesian black opals. Unfortunately, they require a high intensity light to show it's play of color. These opal even came with ridiculous price tags!
The second dealer (another english speaking arabs):
Similar to the first dealer, he also sold a lot of higher end gems. He showed me 4ct indonesian black opals. Like the opal from the 1st dealer, it require a high intensity light to show it's play of color, and it also had an illogical price tags. I felt pretty down. So, I asked if he had any australian black opal. Guess what! He laugh, and said that australia does not have any opal mines He also said that all australian opals are synthetic (WTF).
The third dealer (an indonesian dealer):
He showed me a descent quality black opal that he claimed to be an indonesian black opal. So, I took out my loupe and found out a lot of tiny burn residue. when I asked him if the stone has been smoked, he showed me two different certificate from two indonesian lab. Only one of them concluded that the stone has been treated. Unfortunately, when I asked him about this, he lightly said that there is no natural black opal. Every black opal come from a white one, and we have to treat it. Honestly, I never heard such BS in any gem market I have visited.
I will skip the 4th-13th dealers since none of them have indonesian opal and they all also said that all australian opal are synthetic.
The last dealer (another indonesian dealer):
he showed me a 6ct indonesian that require a high intensity light to how it's play of color, and it came with the craziest price tag. He asked for 1,500,000,000 IDR (around 110k USD). My friend and I immediately left him. Unexpectedly, he keep following and offering us the stone until we reach our car!!!
Honestly, I was thinking that either these dealer has been misinformed or something is wrong with these guys. Not only their price tags are insane, but also the fact that none of them know that australia (especially lightning ridge and coober pedy) produces the best natural opal.
