Materials

18k Gold Plated Jewelry:

Our gold-plated jewelry is made from recycled sterling silver coated with up to 2.0 micron of 18k gold, 8x thicker than the average gold flash plating.

925 Sterling Silver: 

We only use 100% recycled sterling silver. We believe that’s the least we can do to conserve natural resources, lower our carbon footprint and avoid the environmental impact through mining.

Lab-grown diamonds: 

Our diamonds are sustainably grown above ground, in a laboratory that recreates the same conditions that form diamonds underground. 

We only use the best qualities available: 

  • D-F color (colorless)
  • VS1+ clarity (eye-clean brilliance)
  • Very good to excellent cut
Size & Fit

Frequently Asked Questions

Will the necklace chain tangle easily when worn?

No. Our chains are precisely crafted for smooth movement and lasting durability, allowing them to rest comfortably against your neckline while resisting twists during everyday wear.

Can I layer the necklaces?

Absolutely. Our necklaces feature an adjustable length of 41–46 cm and delicate proportions, making them perfect for effortless layering. Pair them also with our pendants worn on colored chokers or silver chains to create a look that’s uniquely yours.

Are lab-grown diamonds real diamonds?

Yes. Lab-grown diamonds are 100% real diamonds. They are chemically, physically, and optically identical to mined diamonds, offering the same fascinating brilliance— at a more accessible price point. Learn more in our Journal: Lab-Grown Diamonds — What to Know Before You Buy →
