The pendant boasts a massive 56.50ct (approximate) genuine oval cut tanzanite which displays a spectacular intense almost pure blue color with just the slightest violet undertone, one of the most sought after colors you can find in today's market.

Tanzanite continues to rise in value due to its rarity and its beautiful, rich violet-blue color. The pendant is also decorated with approximately 4.00ctw genuine VS2-SI1 yellow diamonds, with round cut diamonds surrounding the tanzanite and rose cut diamonds in a variety of shapes interspersed throughout the perimeter of the piece. The pendant is finished with approximately 2.00ctw genuine VS2-SI1/G-H diamonds creating a filigree-style frame, finishing the piece flawlessly. The pendant shows excellent attention to detail, as the yellow diamonds are set in yellow gold to accentuate their radiant yellow color.
