This is the Diamond Ashtray available at Opulent Items for a very high price of $7,250. It has a crown shape and sports three 0.15-carat diamonds of G color and VVS 1 purity.
The ashtray is made from borosilicate glass and has Burj Al Arab written on it. Don’t ask me why. Probably the world’s most expensive hotel in Dubai uses these ashtrays too.
