Dark and grounded
A pear-cut black onyx with lab diamond accents
A pear-shaped brilliant black onyx of about 1.32 carats, set with lab diamonds.
Anchor holds a pear-shaped brilliant black onyx of about 1.32 carats at the front of the pendant. The stone measures about 9 by 6 millimeters, and its dark, polished face reflects light softly, so the pear reads as a clear, steady point at the neckline.
Lab diamond embellishments sit around the black onyx and add small, bright accents beside its deep tone. Each lab diamond is grown in a lab with the same chemistry as a mined diamond, so the setting keeps a clean edge while the onyx stays the strong center of the design.
Black onyx is the December birthstone, which makes Anchor a steady gift for a December birthday. Its dark color suits black coats, dark denim and tailored evening wear, and it keeps the look grounded through a long day.
Steady and clear
A necklace that sits firmly at the collarbone
A 16 inch chain with a 2 inch extender and about 2.53 grams of metal.
The chain is 16 inches with a 2 inch extender, a length that sits at the collarbone and keeps the dark stone in a clear, central position. The extender lets you lower the pendant for a relaxed line or raise it for a neat look.
The metal weighs about 2.53 grams, a steady weight that suits a pendant worn all day. Sterling silver keeps the setting sharp and cool beside the dark onyx, while yellow gold vermeil adds a warm golden edge.
The meaning of strength
Black onyx is often associated with strength, focus and resilience, the steady inner resolve that helps a person keep going through a demanding stretch. Its dark, smooth surface has long been linked with self-control and with a calm, grounded way of facing difficult days, so Anchor suits anyone who values quiet determination. The meaning is yours to choose, and the necklace makes no promise of a particular result.
Some people give a black onyx necklace to mark a December birthday or to a friend who has shown great persistence. Others wear one as a private reminder to stay steady when a plan needs more time than expected.
Choosing your finish
Sterling silver gives the dark onyx a sharp, cool frame that suits minimal and tailored clothes, while yellow gold vermeil adds a warmer edge that looks lovely with gold jewelry and deep, earthy tones.
Measure a necklace you already wear and check where the pendant sits on your neckline. The extender gives you a little more length, so you can try two positions and see which one looks most natural on you.
Caring for the black onyx and finish
Black onyx can chip if it knocks against hard surfaces, and heat, lotion and perfume can dull both the stone and the vermeil. Remove the necklace before swimming, showering, exercise and sleep, and keep it away from hot surfaces and sprays.
After wear, wipe the piece with a soft dry cloth and store it in a separate pouch. Keeping it apart from other jewelry protects the black onyx, the lab diamonds and the finish, so the stone keeps its smooth, dark polish.
Find your metal tone
Two finishes with the same black onyx necklace. Pick sterling silver for a sharp, cool line or yellow gold vermeil for warmth.

Frequently asked questions
Is the black onyx natural?
Yes. Black onyx is a natural stone, and its color and polish can vary slightly from one piece to another.
Are the lab diamonds natural?
No. Lab diamonds are grown in a lab rather than mined. They share the chemistry of mined diamonds.
Is this necklace in stock now?
The necklace is sold as a standard item. Check the product page for the delivery estimate shown there before you order.
Can I adjust the length?
Yes. The chain is 16 inches with a 2 inch extender, so the pendant can sit a little lower when you want more room.
Are the finishes solid gold?
No. The gold finish is 18kt yellow gold vermeil over sterling silver, a thin gold layer rather than solid gold.
Does the necklace promise any effect?
No. Black onyx is often associated with strength, focus and resilience, and those meanings are yours to choose. The necklace makes no promise of a particular outcome.
Can I wear it in the shower or pool?
Please remove it before swimming, showering or exercise. Water, lotion and chlorine can dull the black onyx and the vermeil finish.
How should I clean it?
Wipe gently with a soft dry cloth. Avoid harsh polishes and ultrasonic cleaners, which can damage the black onyx and the finish.
Why is it a birthstone necklace?
Black onyx is the December birthstone, and the pendant suits anyone born that month. The stone is the same whatever the birth month.
