Olivine from Hawaii
Olivine from Hawaii
Paid a visit to Lumahei Beach, here on Kaui, and scooped up a little ‘green sand.’ Be
glad to share, if you will send me an sase with a small ziplock type bag for the sand.
Want more? Send bigger !
I am still on Kauai, but can start mailing in a week. Please note my new address:

You, sir, are no.1, and never to be forgotten. Every time I go in my closet
I stumble over 3 huge scopes, and I mutter something about that Lorez!!!
There is a secret cave on the South of Kauai, where I will be in 2019. I hope
to wrangle permission to get a small sample of their rare green sand.
Aloha
oh, I should fix that. it is dalejohnfiorillo@outlook.com

Re: Olivine from Hawaii
I am just starting out but collecting sand is definitely on my short list! The sand here in Florida seems rather generic compared to the sands in Hawaii! I'll get a SASE on it's way to you if you don't mind.
Thanks,

Re: Olivine from Hawaii
No wiki, oops that’s Hawaiian, I mean no hurry. I did not collect much, only a few cups, as it is a
semi-private and sacred beach. There should be alot of olivine in it.

Re: Olivine from Hawaii
I received my sand today! Quite a bit more interesting than my local sand, with quite a bit larger grains. Taken with a point-and-shoot camera and my biological microscope at 40x magnification. Side lighting (Ikea lamp).

Michael Brock,
Very nice photos, Michael. I have a couple of questions. First, when magnification is mentioned, at what point is the calculation being done ? A scale bar would go a long way in clarifying size, but I completely understand the limitations of the point and shoot camera so this is not a criticism. If these sand grains are the same sample as I received I wonder about the comparison you made to you local sand. As I compare my sample from Dale to my local sand it is quite the opposite. A second question is about the illumination. Did you use transmitted light as well as the Ikea lamps ? I looked at my sample and tried to apply some of your techniques, but since I am currently without a microscope mounted camera or desk top illumination, I didn't have enough hands to do it all, so I just looked. I used polarized light with a wave plate in addition to the little LED flash light and the view was amazing.
If you, or anyone reading this, are sand enthusiasts, I would like to visit about some trades.
All the best to everyone in the group.

Re: Olivine from Hawaii
I totally understand with regards to the magnification. Once you factor in the camera, cropping, etc. it doesn't mean much. They were taken with a 4x objective and a 10x eyepiece. I have a few 10x eyepieces with a reticle. I'll have to research that. Some day I'll have a more permanent camera.lorez wrote: Very nice photos, Michael. I have a couple of questions.

The sand grains from Dale are quite a bit larger than the sand I have collected here in Florida, most of which is very fine sugar consistency. And it has a much more diverse composition. The sand here is comprised almost entirely of fractured quartz.
These were taken with no transmitted light at all. Just an Ikea Jansjo lamp pointed at the slide, at about a 45 degree angle. The incidental light seems to make a much more pleasant image given how thick the grains themselves are. I would definitely like to see sand under polarized light when you do get set up for photography.lorez wrote:A second question is about the illumination.

I am quickly becoming a enthusiast but at this point my collection is comprised completely of a few sands I ahve collected locally (and I'm an hour from the coast!) and the sand from Dalelorez wrote:If you, or anyone reading this, are sand enthusiasts, I would like to visit about some trades.
Re: Olivine from Hawaii
We are in similar positions with respect to quantities of sand. Through the generosity of Dale and others I have collected about 100 samples from a variety of locations. Since many were sent from Europe the quantities are quite small. I'm keeping my samples in 15ml tubes. What I have above my display tube is reserved for trading and a contribution to the college's "world sand collection".I am quickly becoming a enthusiast but at this point my collection is comprised completely of a few sands I ahve collected locally (and I'm an hour from the coast!) and the sand from Dale
Future plans include making a slide of each sample and a cabinet to hold the slides... when does retirement start ???

What are your top 3 most interesting sand samples? I am just curious.
I have around a dozen sand samples, mostly oceanic ones, from around the world (Trinidad & Tobago, Bahamas, Alaska, ect). I like the Hawaii ones best, which have some micro shells and corals pieces there.
Except for those arranged/selected/micromanipulated sand samples, nothing that I have seen beats this one, IMHO: https://www.google.com/amp/ocean.si.edu ... cope%3Famp
I would really like one of those sand samples. Don't know where it came from though. The diversity of that sample seems almost impossible, though I doubt it is selected/arranged/micromanipulated.

Re: Olivine from Hawaii
That sand is definitely unusual! I did a little digging and the photo was taken by David Maitland. He has a website (done entirely in flash...), www.davidmaitland.com. His email address is on the contact page. Would definitely be interesting to know where he collected it. He lives in Norfolk, England and I'm guessing he didn't collect it locally
Re: Olivine from Hawaii
That's a pretty tough question... all of them have aspects that are interesting. More than the sand, it is the story of acquisition.What are your top 3 most interesting sand samples? I am just curious.
Although there are dozens of sites dedicated to sand "swapping" and collection with innumerable members who boast of collections numbering in the thousands of samples, I have found it a bit of a challenge to actually find someone who will swap. It seems that just "not having" a specific sample is not necessarily the catalyst which will lead to a swap. I am not one of those... I have sand that you don't and I will be happy to trade.
Thanks to Dale and all who have helped me with my efforts.

Re: Olivine from Hawaii
I have been looking around for sand swapping sites as well and found the same thing. Lots of suggestion from people that they swap sand but I found none that seem very active. I expected to find a facebook page or two for it but found nothing.
I just bought some sand on Ebay and I'd be glad to trade some with you when that comes in. I'm collecting in 16ml vials currently. Seems like a good volume.

Re: Olivine from Hawaii
I just didn't find my 17 sand samples that interesting, compared to diatom strews or pond water, based on my peculiar taste. So I wonder what an really interesting natural sand sample would look like.
I mean, the foraminifera star sand from Japan is pretty cool, Hawaii sand samples are decent and have some micro shells, Alaska samples have some color and structural diversity, but the rest (Barbados, Trinidad/Tobago) are kind of plain.
It is probably just me

Re: Olivine from Hawaii
This raises an interesting question... "who do you trust?" I imagine there is that unscrupulous entrepreneur who sees that fill sand from the home center looks a lot like that rare sand from just north of the Gobi. There are many collectors who caution against buying anything, but by the same token, I cannot prove the authenticity of any samples I have traded for (except Dale, of course) so I just believe the best and continue my quest.I just bought some sand on Ebay
I will be happy to trade samples. If you would like sand loaded with diatoms I can also provide that. The diatoms are alive when the sand is collected and if I send the sample quickly they will probably be alive when they reach you.

Re: Olivine from Hawaii
I am quite peculiar As a casual hobbyist, I only care if a sample is interesting-looking or not (if I can use it to amaze myself and my kids). Whether or not it comes from a rare or exotic locality does not really matter to me.
It is just like how I collect seashells. I would never pay $$$ for super rarer shells, if it is not pretty/interesting looking. In fact, most of the rarest collector seashells are not pretty at all - they are just rare and nothing else - that rarity itself can command top dollars from some collectors - though rarity can change, once a new revenue (habitat) is discovered.

Surprisingly, I have only a couple of samples from Florida... so, next time you visit Florida think of me.

Re: Olivine from Hawaii
I understand completely. That's not how I operate, but I definitely understand I'm a collector and I have a "collector's attitude". I appreciate just accumulating a variety of things. Obviously the more unique the item is the more collectible it is but like you I don't spend $$ on rare items. In part because I don't have it to spend, but also because there is always something that I don't have that doesn't cost as much. That said, other than postal stamps, sand is the only thing I see collecting to any degree, at least for now. I definitely appreciate the beauty of sand under the microscope , even a pure quartz sand has appeal. And that chance to see something unique is what will keep seeking out more.

Re: Olivine from Hawaii
I have been living in Florida for 8 years and visited many locations but only started collecting sand very recently. I have a grand total of 1 sample collected locally along a stream. I would be happy to trade that of course. I'm hoping to get a chance to go to the coast (one or the other) in a few weeks and start building up some trading stock.
Last night I purchased a few samples from this Ebay seller:
https://www.ebay.com/sch/Other-Mineral- ... sn=papurko
Seems trustworthy on its face. He lists 34 samples from various locations in Bulgaria and definitely all unique images. We'll see. The sands all seem quite different from each other.

Re: Olivine from Hawaii
In my naïve and lazy mind, I don’t understand why people would bother to sell fake sand samples.
First, the small profit ($3 per a routine sample?) is probably not worth the effort. You need list it at eBay, write down GPS coordinates, package it and maybe even drive to post office to send it. Only enthusiastic hobbyists would bother to do that.
Second, faking it takes more effort, at least for beach sand, for example. You need to mix in some micro shells.
Third, in such a niche market, buyers may be very knowledgeable and they examine the sand under microscope. For a popular beach from Hawaii, for example, fake sample may be found out sooner or later and seller’s reputation will be ruined, for little financial gain.
I can see how exotic desert sand would be difficult to prove though.

Re: Olivine from Hawaii
oooooooops, I just made a wild guess, my bad. Try 4 miles at 285 deg. Actually, I
was right by the river, half way between the surf and the trees. Can’t do much
better on this Ipad.
I would not go back to that resteraunt, I got mild food poisoning from bad fish.
Probably cause removing sand from Hawaii is cosidered very bad juju.
