The Diamond is made out of a lovely plastic, and I say "lovely" because it has some texture other than just being glossy. It has an almost matte finish and feels very smooth and velvety to the touch.

Safety Features

The design of the Diamond is very simple: 4" of black plastic (including the battery compartment cap), and the G-spot stimulator extends about 1/4" out from the inside of the curve.

The battery compartment lid measures 1" in length with just over half of that being encrusted with "diamonds" of three different colors - every other row has the white diamonds, and the rows in between alternate between a darker pink stone and a periwinkle stone. That is, it has one column of white, one column of pink on top and blue on bottom, and then one column of white, and so on.

Battery installation is very easy.

The control dial turns easily, and I had no problems with it changing speeds while being used.

The care and maintenance instructions were a bit tricky to find at first, mostly because they were located on the bottom of the box, and the only time I ever look on the bottom of the box is to get the answers to the trivia question on the back of the box. Location aside, they were still better than some I've read in the past.

When you first remove the lid of the battery compartment, there is a little sheet of paper inside that has a picture of a AA battery with the positive and negative ends in the "correct position" that the battery should be in when inserted. That is basically pointy side down so that the spring of the lid can rest against the flat end.

Personally, I just sprayed the Diamond down with a Lover's Lane toy cleaner I already own, wiped it down, and then put it back in the box for storage. I recommend removing the battery from the compartment in between uses to prevent corrosion.
