Hi all. After seeing everyone's mex crazy lace I decided to order some. I ordered it from Minerun Gems. And while I was looking thru their website, I came across some blue topaz that looked cool so I ordered some of that also. Well, 1 out of 2 isn't bad. I received the order today and the Mex Crazy Lace isn't bad, but the Blue Topaz musta lost it's color in shipping. I'm gonna send them an e-mail with a pic of what I received and what they advertised and find out what's going on. Mex Crazy Lace    Here's the Blue? Topaz   Has anyone ordered from them before? Were you satisified and if not, what was their response? |

That is topaz. The blue comes from heating. You will need a kiln some charcoal for absorbing O2 and time. Blue topaz is heated for about three weeks at 1500, London is heated for about six weeks, Day is heated at 1700 for about for about three months. That is why a common stone costs so much as rough, and faceted gems.
In heating the stones, it is critical to obsorb O2. A fluxing similar to Choralski method can work if you can control the conditions to that degree. Tanzanite is the same. Tanzanite is brown ziosite that has been heated. Natural Tanzanite is very rare. Ziosite is very common. Heating turns ziosite into a precious gem. Ziosite and ruby is also common. What a gem ruby tanzanite would make.
Treatments are common in gemstones. Common enough that is not illegal in the gem trades to even list the treatments. Oiling from the mine with emeralds is just doing business.
When working with tanzanite, topaz, emeralds, it is common practice to coat the stone with clear fingernail polish before setting the stone. The graver finishing the setting will scratch the polish before scratching the stone. Removing the polish is another matter. Acetone is common to remove the polish from ruby, saphire, diamond. Acetone will remove the oiling from the emerald and poof! it looks crappy.
By the by. Yellow saphire, white saphire, and emerald is heated for clarity and colour shift. Silver flamed over saphire flux produces yellow. Aluminum flamed over saphire produces white. The saphire must be heated to 1800 degrees to go transparent.

That may well be topaz, and blue topaz is mostly made by heating/irradiating silver topaz, but if they sold it to him as blue topaz, then they should have done the treatment, not expect Stoner to do it. And by Doc's description, there can't be many retail consumers who could possibly be set up to do the treatment themselves.
When I look at their website now, I don't see blue topaz listed. All I see is something called champagne topaz, which is in line with what Stoner got. You don't happen to have a pic of what you saw advertised, do you Stoner?
Nice crazy lace though...

and if they had run out of the blue they should have e-mailed or called you to see what you wanted to do not just send something else.
the mex lace looks nice.

Looks like topaz is alot like Sapphire. Sapphire, from my own experice comes in many different colors. The sapphires I found came in very pale blue to dark blue, blue green and even purple and pink.
The place that I got my stones faceted at, heat treated my 50 sapphires of varying sizes for $79.00. Now I don't know if someone just wanted the stones heated and not faceted if he would do that or not. If anyone wants to know if he would heat topaz let me know and I will send him an e-mail.

Tami,,,,, I find it interesting hat sapphire and ruby (moh's hardness 9) are both corundum and that the only difference between the two are color.  BLUE CORUNDUM  RED CORUNDOM Ruby being red and all other colors being sapphire. Does this mean that a blue ruby and a red sapphire would be called inferior? LOL Also they are both considered corundum until they are made gems! Pretty neat!! Tom  |

Hi all. Well, I did go back and check their website, and now I don't remember if it was actually listed as blue topaz, or just topaz. I might have just looked at the pic, which shows a pound of bluish colored stones, and that's where I got the idea they were blue topaz. That's okay, I played with a few on the grinder last night and it looks like they'll polish up nicely.
