As for our name, we are taking your feedback seriously. We'll think about it some more. Lately, we've been focusing mostly on making this product perfect. It's still a work in progress, but we are getting closer to launching. We wanted to somehow associate it with gemstones. Another alternative was "The Gema Grinder", but we didn't like the sound of it. The meaning was great though. Etymology - Latin gemma "precious stone, jewel", originally "bud". In the end, the decision will be only as good as the alternatives, so we would love to hear your suggestions.
Just spitballing, but if you want something gemstone related, I kind of like the Luster grinder given the looks. Or the Petra if you want the "stone" wordplay without being so on the nose. Considered Petro, but to me that's a gas station chain while Petra only really shares a name with the ancient capital of the Nabataean kingdom.
