I purchased the Tiger Iron cufflinks. These cufflinks are beautifully made. Tiger Iron is a combination of Red Jasper, Golden Brown Tiger Eye and Hematite. You can see all three in each of these 20 mm cufflinks. The attention to detail is quite evident. I searched for a pair of Tiger Iron cufflinks for some time. When I consider the size and value these are the best I found. I absolutely recommend these cufflinks. I'll be looking to purchase more from Thomas Earnshaw in the future.
