I dont have up-to-date information on the current market prices of China Black Granite. However, in general, black granites are considered expensive due to their durability, aesthetic appeal, and rarity. It is possible that China Black Granite is priced higher than other granite varieties due to its unique qualities and sourcing. Prices may also vary depending on the slabs size, thickness, and finish. Its always best to consult with a reputable stone supplier or contractor to get an accurate estimate based on your project specific needs.
