This ring which is partially sand cast with Diamond chips and then additional silver was added to form “rocky outcroppings” - which by the way is what the Shona word, Matombo means.
The “rocky outcroppings” house 3 raw Rubies from the Matombo hills of Tanzania.
Size : fits like a 8 - 8.25 ish due to the organic free form band.
It measures around 7.5 on the mandrel.
