Choosing a black spinel necklace starts with length and detail. These two beaded styles combine black spinel with sterling silver, but their measurements and accents differ. Compare the listed lengths with a necklace you already wear: where a strand falls depends on your neck size and neckline.

Choose the shorter, adjustable strand
The Faceted Black Spinel Sterling Silver Necklace measures 40 cm with a 5 cm extension. Choose it if you want a shorter strand with room to adjust between 40 and 45 cm. Compare its faceted beads, sterling silver accents and heart-shaped end tag in the product photos.
Choose the longer cross design
The Black Spinel Sterling Silver Cross Necklace measures approximately 57 cm. Its textured sterling silver cross sits along the beaded strand. Choose it if you prefer this cross detail and a longer listed length. Both necklaces have a listed weight of around 15 g.
Check your length before buying
Lay a necklace you already wear straight and measure it end to end. Compare 40–45 cm with approximately 57 cm, and consider the neckline you plan to wear. The cross style is approximately 12 cm longer than the faceted style at its full extension. If layering, compare the lengths of the pieces you already own.

Questions about fit and materials
Is the 40 + 5 cm necklace a 45 cm fixed strand?
No. The main strand is 40 cm and the extension adds up to 5 cm. Its usable length is approximately 40–45 cm.
Does 57 cm mean the cross necklace will sit in the same place on everyone?
No. Neck size, body proportions and neckline affect where it falls. Compare a necklace you already wear before ordering.
Can I use silver polish on the whole necklace?
Protect the beads when cleaning silver details. Follow the Jewelry Care guide for the whole mixed-material piece rather than treating it as a plain silver chain.
