Robert Manse Bali Designs 5 Station Marquis Cut Spinel and Sterling Necklace.

The image shows a long necklace featuring black spinel stones set in sterling silver. The necklace appears to be a design by Robert Manse, who specializes in artisan jewelry from Bali. The necklace has a total of five marquise-cut black spinel stones, each surrounded by an ornate sterling silver setting. The chain is made of sterling silver and has decorative elements between the stone settings. Black spinel is a rare gemstone composed of magnesium aluminum oxide and is often mistaken for black tourmaline. It is known for its vitreous luster, which gives it a shine similar to cut glass when polished. The necklace's length appears to be approximately 20 inches, as similar necklaces by Bali Designs featuring black spinel are listed with this length.
