Where Do Pearls and Diamonds Come From?

The origins of diamonds and pearls couldn’t be more different. Though they’re both precious and long-admired jewelry pieces, you’ll find they both have unique histories.

Pearls

From the ancient Greeks to Egyptian pharaohs, pearls have a centuries-long history in cultures all around the world. Mentions of pearl jewelry can be found in several ancient texts—they’ve even been referenced in historical documents from China dating back thousands of years.

While shining gems and sparkling stones are typically formed geologically, pearls are created by mollusks, including:

• Freshwater mussels –Found in rivers, lakes and ponds, freshwater mussels are the most common way to locate a pearl from an inland water source.

• Saltwater oysters – Saltwater oysters can be found on sand ocean beaches, in saltwater marshes or along rocky shores.

Pearls are formed as a defense mechanism against irritant materials. Some mussels or oysters will release nacre, a shiny opalescent substance, as a means of combating parasites or sand grains that have entered their shells. This process can take years—finding a natural pearl is an increasingly difficult process.

In the late 1800s, Kokichi Mikimoto, a Japanese entrepreneur, created the first cultured pearl. By replicating the natural process, Mikimoto was able to create pearls on demand. Over the next several decades, hundreds of pearl farms were built across Japan, lowering the price of pearls and causing massive change throughout the pearl industry.

Key benefits regarding cultivated pearl production include:

• Indistinguishable from “natural pearls” – Cultivated pearls are, in all senses of the word, “natural.” The mollusk goes through the same natural process to create cultivated pearls, and the result is a pearl that is physically indistinguishable from pearls found in the wild.

• Significantly less expensive – For centuries the price of pearls had remained remarkably high. Only wealthy nobles, royalty and aristocrats were able to afford pearls until cultivation was invented. Following Mikimoto’s technological advancements, pearls became accessible to millions and, by the mid-20th century, pearls were an affordable luxury for people across the globe.

• Found throughout the world – Today, pearls are farmed and found in several countries, many specializing in a particular variation of pearls. Whether uniquely shaped or colorful, pearls have retained their position as one of the world’s most beautiful gems, and they remain popular worldwide.

While cultured pearls are natural pearls, they can be confused with imitation/fake ones, determining how to tell if pearls are real can feel difficult.

Diamonds

Diamonds have been a sight of value and wealth for nearly two thousand years. Historians estimate diamonds were traded as long ago as 4 BC, first becoming popular in India where these sparkling gems were found along the banks of major rivers.

Naturally formed within the earth over millennia, diamonds are found in natural deposits deep below the earth’s surface. To bring these natural diamonds to the surface requires extensive mining, and in the late 19th century, the De Beers company began mining operations in South Africa.

Nowadays, there are new options for consumers seeking diamonds. Thanks to innovative technology, you’ll find several options for ethically-sourced and quality diamonds and alternatives to mined diamonds including:

• Lab-grown diamonds – Chemically identical to mined diamonds, lab-grown diamonds are a modern scientific marvel. Through a highly complex scientific process, diamond labs can recreate the natural process of diamond formation, creating a gorgeous, carbon-accurate diamond.

• Diamond simulants – Improving on perfection is never easy. Today, diamond alternatives offer the same look and feel as traditional diamonds, using man-made materials that can replicate nearly every aspect of a mined diamond.

Consumers interested in a high-quality product that avoids the messy history of the diamond industry may find lab-grown diamonds, diamond simulants, or moissanite to be the perfect option for their next jewelry purchase. These options eliminate the deep environmental and ethical costs of mined, natural diamonds while retaining the beauty and elegance of these beloved gems.

What Are The Physical Differences Between Pearls and Diamonds?

Uncertain about the physical properties and look of the gems? Consider the following aspects of pearl and diamond appearances.

Pearls

Whether found in the ocean or cultivated in freshwater, pearls are typically identifiable by the following properties:

• Pearlescence –The shimmering luster of pearls, referred to as pearlescence, is likely the first quality you’ll notice. The nature nacre refracts light, creating an iridescent glow.

• Opaque –Don’t expect to look through a pearl; these gems are completely opaque and won’t let light through.

• Color –Pearls are often prized for their dazzling color. While the standard white pearl color has remained popular, there are several other pearl colors—everything from yellow to blue—to explore. Colored pearls are typically rarer and more sought after than standard-colored pearls.

• Shape –Perfectly spherical pearls are certainly prized as the perfect addition to a ring, bracelet or necklace. That said, irregularly-shaped pearls, known as “baroque pearls,” have come into fashion as well, and may be considered more unique or interesting to some consumers and jewelry designers.

Diamonds

Shimmering, shining and highly reflective, diamonds are unmistakable. Diamonds are widely known for their physical beauty, but it may be worthwhile to explore the 4Cs, the four key ways of defining a diamond’s appearance:

• Cut – Depending on the process of manufacturing, a diamond may be cut too shallow or too deep for a proper fitting. The highest quality diamonds are considered Ideal Cut, meaning they hold the proper shape. Additionally, it’s important to remember that diamonds come in several cut styles, including emerald, round and oval.

• Color – The standard diamond color is a perfect translucence—like glass or ice, two common nicknames for diamonds. High-quality diamonds are colorless, while less-perfect stones may have a yellowish tint.

• Carat – Diamonds are measured in carats. A carat refers to ⅕ of a gram, meaning the higher the carat of a diamond, the heavier and larger the stone.

• Clarity – The clarity of a diamond will vary depending on the absence or presence of blemishes and imperfections. They’re often graded by gemologists on a scale ranging from flawless (without blemishes) to included (containing obvious blemishes under magnification).

Engagements Rings: Pros and Cons of Pearls and Diamonds

Pearls

Pearl jewelry can be found in different variations, from a pearl necklace to earrings and even an engagement ring.

Pearl symbolism includes embodying the virtues of trust and loyalty, making them a beautiful symbol for those interested in proposing with pearls. Pearls also embody elegance and are timeless in jewelry pieces.

Diamonds

Diamonds symbolize commitment, passion and long-lasting love. They remain one of the most sought-after gems in the world, and can be found in a variety of pieces, including pendants, earrings and, of course, engagement rings.
