You wont be able to tell. Buy from a reputable retailer and make sure you have a cert of authentication. Let them do the homework. Certain countries that shall remain un named will print a fake cert without blinking. If you buy from a reputable dealer, consumer law protects you.

Saws and Diamond Blades / Re: saw blades...which one to buy???

If you want the best either a Highland Park blade or a Ukam blade. They are both professional industry quality blades.

Only saw I would buy would be a Highland Park from flat lap in Townsville

The one in the picture is from lapidary slabs and supplies in Mackay. They are a swing saw and perfect for clubs because they are harder to abuse the blade.

Crystal belts versus Eastwing versus Silicon carbide?

Best and most economical option for moderate use taking in to account purchase cost.

I am starting to think the pink is just to distinguish it from tin oxide

Gemstone Faceting / Nonosital angles.
« on: November 11, 2018, 12:44:15 PM »
I am just starting out so doing some round Brilliants in Nanosital for practice. My diagram is for quartz. What angles should I use for Nanosital? Would I use Topaz angles?

Head to a sheet metal place. Also track down mining engendering ok places. They might have some scrap. Try  the scrap metal places too. Do you want woven mesh or perforated sheet? You will find it  in Mackay. If you search online for stainless steel mesh you will find suppliers but at a minimum amount plus freight.

Contact the term. They will be more than happy to give you the details

Tumblers and Media / Cerium oxide
« on: November 02, 2018, 05:31:22 PM »
Another question I have not been able to find a decent answer to. Pink and White Cerium Oxide. I believe the pink has Praseodymium added but what effect does this have? I am guessing it is actually Praseodymium oxide. When would you use one over the other?

Gemstone Faceting / Nanosital polishing
« on: November 01, 2018, 07:14:51 PM »
Does anyone know if Nanosital can be polished like quartz? That is, with an Ultralap or Cerrium oxide on perspex.

Saws and Diamond Blades / Glueing Dops for slabbing
« on: October 17, 2017, 03:41:21 PM »
What's good for gluing rock to wood for slabbing? Is liquid nails construction glue type of thing any good? A lot seem to say Sodium Silicate but that sounds very old fashioned. Is it or is it the best?

Why not trim close with a band saw instead of using something akin to using a thermal lance?

Notched is generally cheaper but I would go the extra for a continuous sintered blade. For general slabbing use, don't try go too thin either. Check out the general info on smart cut diamond tools website.

Another question on said wheels. Manufacturers often state maximum speed or RPM. What speed or RPM is generally a best compromise for common use such as silica based stones.
