General Information on Crushed Diamond/Tunstall Engagement Rings
The finish was invented by our chief goldsmith Richard Tunstall as an alternative to the pin end finish. Although the pin end finish is a fairly durable finish, Richard felt that it would be possible to create a finish that was even more durable and he came up with this.
Adopted by other companies now, this finish is also known as a 'crushed diamond' or 'diamond dust' finish and is applied to the surface of an engagement ring in much that same way as a pin end finish - ie by distressing the surface of the engagement ring by hand.
This finish is very marked and through will need to be given right from the start of the design process if you are considering this finish for your engagement ring as the finish works best on large flat areas of metal. The finish wouldn't be appropriate, for example, for a delicate engagement ring.
