Chlorite in Quartz
The layered inclusions on the face of the crystal look like that of a thumprint, check out the zoom up below:
Chlorite inclusions are very common in alpine-type environments, and generally occur in fissures and pockets inside igneous and metamorphic rocks, and in sedimentary rocks that are rich in clay minerals. "Chlorite" is actually the name for a group of phyllo-silicates (sheet-silicates), minerals of mica-like appearance. The name refers to the very common green color, although chlorite minerals do not have to be green.
Chlorite minerals form at low to moderate temperatures. Often quartz from alpine-type clefts has a chlorite "icing" on the crystal surface, giving them a rough and dull look, because the crystals started to grow at high temperatures, and when their growth slowed down at lower temperatures, chlorite formed in the pocket and settled on the crystal faces.

Amethyst flowers
Unlike its deep, dark purple cousins, this piece demonstrate the diversity of amethyst in general, and the highly unique and rare character of this amethyst in particular. This gorgeous mineral is simply elegant!

Chinese seal carved from quartz
Most people in China possess a personal name seal. Artists, scholars, collectors and intellectuals may possess a full set of name seals, leisure seals, and studio seals. A well-made seal made from semi-precious stones can cost between ¥400 and ¥4000.
Seals are still used for official purposes in a number of contexts. When collecting parcels or registered post, the name seal serves as an identification, akin to a signature. In banks, traditionally the method of identification was also by a seal. Seals remain the customary form of identification on cheques in Mainland China and Taiwan but not in Hong Kong where signatures are required. Today, personal identification is often by a hand signature accompanied by a seal imprint. Seals can serve as identification with signatures because they are difficult to forge (when compared to forging a signature) and only the owner has access to his own seal.
Seals are also often used on Chinese calligraphy works and Chinese paintings, usually imprinted in such works in the order (from top to bottom) of name seal, leisure seal(s), then studio seal. Owners or collectors of paintings or books will often add their own studio seals to pieces they have collected. This practice is an act of appreciation towards the work. Some artworks have had not only seals but inscriptions of the owner on them; for example, the Qianlong emperor had as many as 20 different seals for use with inscriptions on paintings he collected. Provided that it is tastefully done (for example, not obscuring the body of the painting, appropriate inscription, fine calligraphy, etc), this practice does not devalue the painting.
Seals are usually carved out by specialist seal carvers, or by the users themselves. Specialist carvers will carve the user's name into the stone in one of the standard scripts and styles described above, usually for a fee. On the other hand, some people take to carving their own seals using soapstone and fine knives, which are widely available and is cheaper than paying a professional for expertise, craft, and material. Results vary, but it is possible for individuals to carve perfectly legitimate seals for themselves.

Enhydro Quartz Crystal
Defacing the art of Mother Nature?
Not really... but rather the arrow marks the location of an important inclusion in this crystal! It is a Enhydro Quartz Crystal .
Technically speaking, an enhydro is "a hollow nodule or geode of chalcedony containing water, sometimes in large amounts" per the The American Geological Institute’s Glossary of Geological Terms. As such, these crystals are actually not enhydros but more accurately referred to as "quartz with bubble fluid inclusion".
These crystals formed millions of years ago (220-400 million years ago by some estimates) as the edges of the quartz formed faster than the center. As this happened, troughs were formed that trapped the water solution or other foreign matter. When these troughs were covered by more crystal growth, the captured water (sometimes salt water or other liquid) would "gas out" or cool and contract and a bubble would form in the liquid.Enhydro water bubble quartz is a true spectacle of nature. Being able to see gas bubbles move in solid rock that was formed millions , or perhaps even billions, of years ago is hard to imagine but enjoyable to watch!
