De Lena Blue is a beautiful tennis bracelet finished with dozens of 2mm blue aventurine natural stones. Making this bracelet takes a lot of time because each stone must be individually adjusted to fit this fine bracelet. All Didyma jewelry is made from 316L stainless steel combined with beautiful natural stones. We chose this material because it is very durable, lightweight, and hypoallergenic. The color will not fade over time. Blue aventurine is a blue type of quartz gemstone.
