BOTTOM STABILITY WRAP is a little wrap of wire on the bottom of the ring to help stabilize the rings. There is no extra charge for this option. This option is not shown but you can see it here: www.etsy.com/listing/96443601/mahogany-obsidian-argentium-sterling
I recommend this for sizes 8+.
This bead is 8mm which is just over 1/4 inch.
I can make this ring in whole, half and quarter sizes 2-16.
Please let me know what size you need by selecting the proper size in the drop down menu above the green "Add to Cart" button.
