Considering a recent case of another sellers pre-loaded coins being compromised :

https://bitcointalksearch.org/topic/alitin-mint-adam-smith-2btc-coins-compromised-1814916

To maintain security I am happy for any buyer just to send me a public key & QR code to be engraved, can be generated here:
https://www.bitaddress.org/

You can then keep the private key secret and I will send a hologram to secure to crystal.

If you're going to do this please add something to the design (A small "DIY" somewhere?) to show that the address was not generated by you. These buyer generated pieces will sell for less on the secondary market because there will be no trust at all in the security of the key.

Not a problem hox, if people opt for DIY I will mark it so yours is not negatively impacted (above QR code)

I'd think the COA would be a good place to mark it DIY but I do understand the COA's get lost and someone may believe the manufacturers generated key is on there.

I'd love to see a video of your laser in action doing one of these pieces.

Quick bump.

Also had a few inquiries @ urbanartassociation.com thanks to the Banksy linkage.

As BTC price is on the up I have fixed the price in fiat using btc-priceimg

Are you purchasing #1, Hox?

Mark, is it serialized on the crystal?

The crystals are not serialized but the CoA's are.

Thanks for the comparison pic and weight, it's a really unique item and I'm heavily debating it. Grin

If you don’t believe, why are you here?

I think it's a real nice pick up. Augmenting the Banksy concept is a great touch and will appeal to a wide community. In fact, I was about to be a dick and just send BTC before you but I thought better of it Grin

How/where is the private key attached?

I'll take #1 depending on the answer.

edit: Also any pictures of the CoA?

Mark,
Exceptional work on this piece, it has exceeded my expectations! I did the conversion for the sizing and am wondering if you can add a picture with something else like a dollar bill to show the scale. Also the weight of the crystal would be a desired spec.

Thanks again,
digicoinuser

Its a fairly big chunk of crystal coming in at 1.8kg boxed with the LED light base (which weighs very little)

Crystal size(Large) = 110 X 75 X 65 mm

Here is a pic next to a standard sized bank card to give an idea of scale (LED base adds about another 1/2" to the height) :

Private key is secured under a security hologram on the LED base although if you prefer I could also place it on the COA.

Absolutely stunning piece! I love how the art just pops out.
I'm really tempted but probably shouldn't. I'm terrible with saving BTC. Somehow I'm amazing at spending it Grin

Good luck with the sales. I'll definitely be watching this closely.
