Hi Mike. Once again, nice photos. The smoky has a good colour. Is it common, and up to what size do you find them? Best regards.

Thanks Pierre; small crystals (1-2cm) are fairly common; large crystals (5-7cm) are rare. They can be found loose on the ground sometimes, otherwise from miarolitic cavities (where many small or a few large crystals can be found). They are most often damaged at the termination due I think to frost/ice action in the wet mud/gravel in the cavities - one drawback of a cold winter climate !
The few specimens I have which are undamaged were found in cavities that were dry, well-drained, or more open. The next specimen is from a different locality.

Hi Mike,
Small quartzs but with an incredible transparency and beautiful deep color. The association of this kind of quartzs with microcline or amazonite is one of my favorite mineral compositions.
Regards,
Juan H

Hi Juan, glad you like them; I must confess I am a fairly recent convert to quartz appreciation, but I have seen the light ! And it is good !
Combination of smoky quartz and microcline feldspar are even more rare, but I have a couple of specimens, here's one..

Smoky Quartz + Microcline

8cm x 7cm high x 4cm

Be sure you will be possessed by quartz power :-)
The dark quartz with the white-cream microcline is stunning.
Thank´s for sharing it!

Here are four similar sized smoky quartz crystals with different themes of formation, all from the same cavity. The two on the left have damaged terminations; the two on the right have not. Then we have something unusual from a separate location.

| How wonderful to have found that Arran aquamarine. Do you have Mourne examples to go with the Scottish ones? The feldspar twins are also very fine.

Ru, I don't have any similar Mourne Mountains (N.I.) aquamarines, just a small greenish beryl on matrix which I bought. I've never been across the water to Ireland, but if I did, the Mournes' would be top of the 'to do' list !

These specimens are from a different cavity. The smoky quartzes are very deeply coloured, almost black, but with very clean lines and incredible lustre. The feldspar is a bit different also.

Stunning Manebach feldspar twins!! I think Manebach twins are single, not polysynthetic, but they look like so.

Nice sturdy smoky quartz crystal; the termination is a little chewed up (as found) probably from ice-action in the cavity where it originated from. The crystal had actually 'migrated' a short distance from the cavity and was wedged in a crevice. The crystal colour has lightened on one side due to exposure to the sky - best seen in the third photo. Self-collected. |

I've got a feeling I've been calling these feldspar crystals orthoclase instead of microcline. Now I'm confused. It's a pretty poor state when a field-collector doesn't know what he's collected. I'm sorry about this; maybe I should change all my captions on the 'orthoclase' feldspars.
In the meantime, I'll post a few more photo's of things that aren't minerals from Arran, but are hazardous.. and from Arran.
| Description: |
| Cioch na h-Oighe (661m) viewed from Glen Sannox. Around the edge of Arran nearer sea-level the scenery is quite verdant and lush in the summer, but the summer months have added hazards. For example, this photo was taken in July, so it is quite likely there are millions of midges in the trees and undergrowth. They are everywhere if there is little wind and the weather is damp, even on the mountain tops. Sure, you can use DEET on yourself which stops 'em biting, but they still land on you briefly and they tickle. They don't like strong sunlight, thankfully. They don't like cold weather 12C or below. Midge season is usually mid-may to early october. |

| A large deer tick on the prowl. This one was about 4mm long (body) and the red part on it's abdomen indicates that it is mature and has fed on some thing. Mostly they are a bit smaller and can be very hard to spot when they are <1mm. They hang around in long vegetation (grass, heather, bracken, trees) and wait for prey to walk past. They have caused serious infection in some parts of the UK in the form of Lyme Disease. I've been getting bit by these suckers for twenty years or more but I'm still ok (I think). Tick season - probably april to october. |

| Horseflies, also known as Clegs, are nasty. They have a somewhat 'furry' appearance, sort of dusty-grey colour. You can't hear them flying. You can't feel them land. If you're quick and recognise the sensation you can swipe them off you just as they start to bite; then the bite will only itch a little ! Unlike midges these things are active in bright sunshine. They are about during the months of July and August when it's warm. It's best to keep moving when these are around, and keep an eye on them but they are very distracting. They are mainly living in the valleys; it is usual to have several following you as you walk. And they can bite through thin clothing !! |
