Tantalum is a beautiful gray color with a hint of blue. It’s that great gun-metal tone that’s darker than titanium but not black like zirconium. It is quite dense, with a weight similar to platinum. While many alternative metals create difficulties with resizing, tantalum is quite malleable and easily resized up to one size depending on customization. Tantalum is hypoallergenic, and will not corrode or react with exposure to everyday use or chemicals.
