Deep blue steadiness
A pear-cut blue sapphire with lab diamond accents
A pear-shaped brilliant blue sapphire of about 1.72 carats, set with lab diamonds.
Thread holds a pear-shaped brilliant blue sapphire of about 1.72 carats at the front of the pendant. The stone measures about 9 by 6 millimeters, and its deep blue tone is rich and even, with the pear's pointed tip leading the eye toward the collarbone.
Lab diamond embellishments sit around the blue sapphire and add small points of light beside its depth of color. Each lab diamond is grown in a lab with the same chemistry as a mined diamond, so the setting catches the light while the sapphire keeps its quiet, steady presence at the center.
Blue sapphire is the September birthstone, which makes Thread a meaningful gift for a September birthday. The deep blue suits navy knits, tailored jackets and evening dresses, and it stays elegant through a long day.
Elegant and steady
A necklace that rests well at the neckline
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 puts the blue stone in clear view. The extender lets you lower the pendant for a relaxed line or raise it for a close, neat look.
The metal weighs about 2.53 grams, a steady weight that suits a pendant worn all day. Yellow gold vermeil adds a warm frame that sets off the blue, while sterling silver keeps the sapphire crisp and cool.
The meaning of loyalty
Blue sapphire is often associated with wisdom and loyalty, the steady trust that holds friendships and partnerships together over many years. Its deep blue has long been linked with calm thinking and with a faithful, dependable character, so Thread suits anyone who values lasting bonds. The meaning is yours to choose, and the necklace makes no promise of a particular result.
Some people give a blue sapphire necklace to mark a September birthday or to a friend who has always been there for them. Others wear one as a quiet reminder of the people and commitments they keep close.
Choosing your finish
Yellow gold vermeil adds a warm frame that makes the blue look especially rich, while sterling silver keeps the sapphire crisp and cool, which suits a clean, modern wardrobe.
Measure a necklace you already wear and check where the pendant sits on your neckline. The extender gives you extra length, so you can try two positions and see which one suits you best.
Caring for the blue sapphire and finish
Blue sapphire is very hard, but it can still be chipped by a hard knock, 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 blue sapphire, the lab diamonds and the finish, so the blue keeps its clear, deep tone.
Find your metal tone
Two finishes with the same blue sapphire necklace. Choose yellow gold vermeil for warmth or sterling silver for a cool, clean line.

Frequently asked questions
Is the blue sapphire natural?
Yes. Blue sapphire is a natural gemstone, and its blue tone varies from one stone 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. Blue sapphire is often associated with wisdom and loyalty, 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 blue sapphire 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 blue sapphire and the finish.
Why is it a birthstone necklace?
Blue sapphire is the September birthstone, and the pendant suits anyone born that month. The stone is the same whatever the birth month.
