Instead, try to make all the tags first, then take those exact tags (4-7 of them) and string them together to make your title. You can separate the phrases (tags) with commas to make it easier for the shopper to read.
The reasoning behind this is:
The way search works (usually) is when a shopper types "wide band ring" into search bar, it will see all of the listings that have "wide band ring" exactly in title AND "wide band ring" exactly in one tag. After all those listings, then it shows items who have it in one place (either in tags, or in titles). Then after those, it shows items who have it spread out or a different order than what the shopper typed, "ring with wide band" for example.
So it is extremely important to
1. Think of good phrases that shoppers use
2. Have that phrase in title
3. Have that phrase in one tag exactly the same as it is in title
