Anyone know where I can take a collection of my diamonds and have them made into a wedding ring in Dallas?

I have some really nice diamonds from a necklace, ring and earrings that I would like to have designed into a wedding ring. I have been married for 8 years and my husband wants to get me a bigger ring, but we really don’t need to spend the money. I have these diamonds from jewlery that he has bought me and thought maybe we could have them made into a ring.
