Yes, all our pearls are natural and ethically sourced. We have our own pearl cultivation farms, which allows us to carefully select only the highest quality pearls. We prioritize ethical standards and use gentle, sustainable methods to produce non-nucleated pearls with exceptional luster and superior quality.

4A pearls offer superior luster, shape, and rarity — perfectly round pearls are rounder, and baroque pearls have a richer shine. These are reserved for our finest pieces. 3A pearls still meet our high standards for beauty and quality, making them a more accessible choice without compromising elegance

We use high-quality sterling silver, plated with genuine 18k gold, enhanced with a rare rhodium coating that adds a luxurious shine and durability. Our pieces are nickel-free and hypoallergenic, offering a superior look and feel compared to standard silver jewelry.
