How to discern the true and false of agate?

I had bought false agate, also had collected true agate on Xinjiang big desert, say my experience.

If you had gathered stone on Xinjiang desert beach, you can discover actually agate hand is strung together not costly, because be mixed at Xinjiang relatively cropland jade, Ma river jade, lapidary light can meet the baby that cannot beg, desert agate, currant agate is collected relatively easily still, an agate hand strings together 50 money to attribute regular price. But why don't I recommend everybody to be bought in ground booth, because the ground spreads out hand of on a lot of agate is strung together,be to use 2 to 3 true agate, deserve to go up 5 to 6 false agate (artificial synthesis) , holiday of true true and false comprises a hand to string together, such I is duped, young scrutiny is done not have when buying, discovery of ability coming home was duped.

I had collected pure natural agate in berth of the agate beach of Xinjiang, collect cloth, true agate has qualitative feeling very much, have oily, color slants dark but can glance, color is primary it is ivory, dark yellow, wine, sap green, coffee a few kinds, the first look not to have an eye, have foreign matter even, but often such agate is true fellow.

If you are bought agate too too transparent, a bit impurity is done not have, the price is not particularly high (2000 yuan of less than) , big probability is buy a holiday. So, want to do truly know agate must actual combat a few, come namely Xinjiang desert beach turns, see see true natural agate is oily how? Density how? Colour and lustre is bright, if ramble every day jade market, it is to take exercise not to come out of the feeling of this kind of eyesight.
