Pearls have long been cherished for their timeless elegance and natural beauty, but not all pearls are created equal. One of the most fascinating aspects of these lustrous gems lies in their origin — freshwater and saltwater environments. While they may appear similar at first glance, the differences between freshwater and saltwater pearls go beyond their surface, influencing everything from their formation to their value. Understanding these distinctions can help you appreciate the unique qualities of each and make an informed choice when selecting your perfect pearl.
Origin Story

Freshwater pearls are cultivated in rivers, lakes, and ponds, primarily in China. They grow within freshwater mussels, which can produce multiple pearls at once. Saltwater pearls, on the other hand, originate in oceans and are typically cultivated in oysters. They are the only gemstone that comes from a living creature. The most common types of saltwater pearls include Akoya, South Sea, and Tahitian pearls. Saltwater oysters usually produce a single pearl at a time, contributing to their exclusivity.
Appearance and Variety

One of the most noticeable differences between freshwater and saltwater pearls is their appearance. Freshwater pearls tend to have a softer luster and come in a wider variety of shapes and colors, ranging, from cream and soft pink to lavender and even metallic hues. Additionally, they form in a variety of shapes, including round, oval, button, and baroque, offering endless design possibilities for unique jewelry pieces. Saltwater pearls, in contrast, often exhibit a more brilliant luster, rounder shape, and classic cream color.
Nacre

Nacre, the substance that gives pearls their iridescent glow, plays a significant role in determining their durability. Freshwater pearls are composed almost entirely of nacre, giving them exceptional resilience and a unique, satiny sheen. Their durability makes them suitable for daily wear without the worry of losing their luster. Saltwater pearls have a thinner nacre coating due to the bead nucleus used in their cultivation, resulting in a sharper luster, but less durability.
Price and Accessibility

Price is another major distinction. Freshwater pearls are generally more affordable because mussels can produce multiple pearls at once, and their cultivation process is less time-intensive. Saltwater pearls, being rarer and more labor-intensive to produce, command higher prices. One of the most compelling reasons to choose freshwater pearls is their affordability, which allows for more creative designs and makes pearl jewelry an option for everyday wear, not just special occasions. Sustainability can also play part in your choice between freshwater and saltwater. Between the two, the cultivation of freshwater pearls is more environmentally sustainable than other pearl farming methods. Freshwater mussels can produce multiple pearls at a time, reducing the need for extensive harvesting. Many farms practice ethical methods, ensuring the process respects both nature and local communities.
What about Natural Pearls?

Natural pearls are incredibly rare and distinct from their cultured (freshwater or saltwater) counterparts. In fact, only 5% of pearls on the market are natural. They form without human intervention when an irritant, like a grain of sand, accidentally enters a mollusk, triggering the slow secretion of nacre that builds up over time to create a pearl. This organic process can take years, making natural pearls highly prized for their uniqueness and value. In contrast, cultured pearls are deliberately cultivated by inserting a nucleus into the mollusk to stimulate nacre production. While both types share beauty and elegance, natural pearls are often considered more precious due to their scarcity and the unpredictability of their formation. Maybe that’s why Roman ruler Julius Cesar passed a law where only aristocrats could wear pearls within Rome's borders (facts).
Choosing the Right Pearl for You

When deciding between freshwater and saltwater pearls, consider your personal style and intended use. Freshwater pearls are perfect for playful, modern designs due to their variety in shape and color. Saltwater pearls lend themselves beautifully to classic, refined pieces that exude timeless grace.
Birth of Venus Collection

Venus, the Roman goddess of love and beauty, has long been associated with pearls due to her mythical origin and symbolic ties to the sea. According to legend, Venus was born from sea foam and emerged from the ocean on a shell, much like a pearl forming within an oyster. The Birth of Venus Collection from Cold Gold is a tribute to Botticelli’s iconic painting, capturing the essence of beauty, transformation, and the sea.
