This 28.4 carat softly rectangular limestone dendrite specimen is new to me (first piece cut and shaped from slab)! The scene displayed is dendrite formations that occur from water pushing minerals through layers of limestone; time being a major ingredient. This limestone cabochon has a matté finish over a high polish surfacing, and suggests an absorbing softness that resonates to a non-obtrusive presentation. Bezel set and accent links of 22 karat gold. Solid back base and chain of oxidized sterling silver .925. Total necklace length is 20.5 inches. Pendant measurements are 34.5 mm horizontal x 27.5 mm vertical x 6.25 mm gem height.
