This logo is in the Persian language. The main concepts of this logo, which also have a common aspect, include the last letter of this logo in the form of a needle as a symbol of sewing work in this profession, and the shape of a diamond as a symbol of jewels, which has passed through the needle (last letter) in the form of a thread and ultimately represents a pearl, which also means pearl in the Persian language. The two dots of the letter T are sewn together with the same needle. The combination of these three concepts refers to the process of jewelry embroidery, especially the pearl-like (referring to the scarcity of pearls).
