The Amethyst is made for finding and stimulating the G-spot. It has one end that's just a few simple ripples, ideal for warm-up, but the other end is the one that really shines: it's curved and has a pointy tip with flat sides that's perfect for stroking the G-spot. I normally have problems with very firm toys crashing into my cervix, but the curve on this one makes it difficult for that to happen. I can thrust away without worrying about damaging myself.

While glass ripples can feel awesome anally, this toy is not intended for that purpose. It doesn't have a flared base and is too slippery to be counted on to stay put if you try to use it in your ass.

The Amethyst is made of Pyrex glass. It's nonporous, so it can be sanitized by boiling, washing with soap and water, or wiping down with a 10% bleach solution. You can also put it in the top shelf of your dishwasher, but I'd be too worried about mine getting scratched if I did that.

Glass is odorless and tasteless. It's, of course, very hard to the touch, and completely unyielding, making it great for applying tons of pressure to your G-spot, if that's what you're into. I find that it's a better choice than silicone for this purpose because silicone is slightly bendy and doesn't do the job as well as glass and stainless steel do.

The Amethyst is smaller than I expected it to be, but this tends to be true for G-spotting toys: they're not intended to be filling, just to hit the right spot and stimulate it.

I thought that the G-spotting end would be uncomfortable, because of its intense curve and pointy head, but with my anatomy, the pointy part of the head doesn't jab me. It's the side of the head that does the stimulating, and it feels very good. The Amethyst also has another insertable end, which provides a little bit of texture and is good for building arousal, but I didn't find it all that exciting.

The only thing I don't like about the Amethyst's design is that I sometimes can't tell which direction the G-spot head is facing when it's inside me, so I have to take it out and check. I wish there was some sort of indicator on the handle. I may even make a little Sharpie mark there, so I'll always know which way the dildo is oriented.

Because this toy is so unyielding and usefully shaped, it does its job (applying pressure to the G-spot) very well - better than any other toy I've tried so far. I can thrust with it, rock up into my spot with it, or even just clench around it, and it feels really good. It definitely produces that "need-to-pee" feeling, which is a telltale sign that it's stimulating my G-spot.

I found that I sometimes wanted something a bit more filling because the Amethyst is such a slim little thing. As good as the G-spot stimulation felt, I sometimes just wanted to clench around a huge phallus, which this toy couldn't provide.

The toy comes packaged in a red velvet pouch, which is perfect for storage - I wish every toy came with one of these! It protects my Amethyst from lint, dust, and from touching other toys.

Glass is compatible with any kind of lube you want to use with it. It doesn't eat lube the way silicone does, so you may not need to re-lube as often as you would with some other toys, or at all. It's easy to clean with soap and water, or even just a toy wipe. And like all glass dildos, it can be boiled for ultimate sanitization.
