These awesome weights are entirely handmade from raw materials here in my UK workshop. I have a range of stones that are available for these weights which I will try to keep up-to-date but if you want something specific that isn't on the list just drop me an email to see what I can do for you. There are several options for the metal copper/brass are the main materials I use for these and cost no extra, but I can also order in silver or gold specially for these but they do add to the cost and production time. Please note that these are a very time consuming item to make, and depending on my production queue will likely take me longer than the 2 weeks aim to get them made and ready for shipping.
There are 2 size options available in this product listing the mini weighs roughly 20grams per piece and measures 18mm at the widest point and 50mm high. The full size weighs roughly 35-40grams per piece and is 28mm at the widest point and 80mm high. As each one is hand made and some stones weigh more or less so there will be some variance in these dimensions/weights. The coils are made from 3mm diameter wire and are roughly 25mm in diameter with a 5-6mm gap.
The designs on these vary between the full and mini size, the full size is the rose quartz in brass setting pictured and the mini is the green moss agate in copper so please keep this in mind when making your selection.
