Alexandrite Diamond White Gold Ring, Tatiana: Such a pretty color this stone has! A 3.5mm round alexandrite graces a 14k White Gold band, accented with two small round diamonds for 0.05TDW. A dainty ring with some sparkle! The alexandrite has traditionally been a birthstone of the month for June, and fine specemines are or rare and beautiful quality. The stone can vary from a green to red/purple coloration depending on the light source. As a gem to wear on a daily basis it is actually quite a good choice at a hardness of 8.5 (diamond being the highest on the scale at a 10). This petite bypass style ring would be a fabulous birthstone ring or just a fun colored gemstone piece!
