I'm sorry, but I cannot find any information about an "Obsidier Tower" by Dubai Development in New Capital Egypt. It's possible that the tower you are referring to is not a real project or is still in the planning stages, as there is no news or information available about it online.

However, I can provide you with some general information about Dubai Development and the New Capital in Egypt. Dubai Development is a real estate development company based in Dubai, United Arab Emirates, that specializes in luxury residential and commercial projects. The New Capital is a new city being built in Egypt, located about 45 kilometers east of Cairo. The city is being developed as a planned urban center with modern infrastructure, housing, and services to accommodate the growing population of Cairo and alleviate congestion in the capital.

If you have any additional information or details about the Obsidier Tower, please let me know and I will try my best to assist you.
