Investment Fund needs a timeless logo

Obsidian Equity Management

This logo is for a hedge fund, but instead of being super focused on creating a traditional finance style logo think of this company more as a tech finance company. Modern, sleek, and timeless is what i am going for.

My target audience = high net worth individuals and institutions (endowments, pensions, sovereign wealth funds, family estates, etc.)

I would like a black or a light black to be a part of the color scheme but am open to other colors.

*UPDATE* A few of the designs I have seen so far are for more traditional finance companies. I am looking for something more modern and techy. Here's a question to ask about your design, would the logo look good and unique as an app icon on the iPhone? I am not creating an app, but I think this question will help guide your artistic flair!

-I do like geometric type logo's. It doesn't have to be a literal translation of obsidian, but should be a figurative interpretation of the adjectives I listed below.

-Please don't submit anything cliche to traditional finance companies. Like a line chart with an increasing equity line, or a bar chart with increasing bars

-I am open to different color schemes, but Red is difficult to use since it is associated with losses in finance

A marketing friend of mine asked me for a few things I believe to be apart of my competitive advantage. I posted a few of the adjectives I came up with below to help guide you:
Flexibility
Nimble
Systematic
Perspective
Mathematic
