OK, that makes sense. Thanks. I just spoke to my wife's grandfather about this because he is originally from near the Pochaiv monastery in Volynia, Ukraine.
Here is what he said and suggested for you. The icon of the Theotokos of Pochaiv in the Pochaiv monastery itself is covered with an elaborate riza, hanging over the Royal Doors of the iconostasis
The riza is made in the shape of a star pattern with rays many jewels.
In our parish we have a small copy of the icon and riza also hanging over the Royal Doors. But the riza we have only has stones (not jewels) in the eight corners of the star. Also the original icon and riza in Pochaiv is quite large so consider a smaller version as in our parish.
Here is what my in-law suggested:
Contact Istok Church Supplies at 403-220-9316 or via their web site at
http://www.istok.net/and see if they can get a copy of the icon for you and also have the riza made for you out of metal with engravings of all the rays but without the real jewels or with a few rhinestones or other stones in the corners as in the riza at our church. They would have it made for you in either Ukraine or Russia at a cheaper rate than here. You can ask them for an estimate. Also ask for a discount since you are donating it to a church.
There are a number of Ukrainian Orthodox parishes in Canada that have the Theotokos of Pochaiv icon and riza so my in-law said it must be being produced somewhere and thus available for you to buy. Also he said there are many churches in Ukraine with copies too.
Istok Church supplies has been in business since 1999 and is very realiable. Their prices are very very fair.
Good luck and we hope it works out and you can order it.
