  • Center lab sapphire — measures 6 by 4 millimeters and features a bead prong setting for a secure hold.
  • Cable chain — suspends the pendant and fastens with a lobster clasp for secure everyday wear.
  • Adjustable chain length — can be adjusted to 16, 17, or 18 inches to suit individual preference.
