GORGEOUS GRANDIDIERITE: THE 7TH RAREST GEMSTONE IN THE WORLD

A REMINISCENT OF TROPICAL WATERS

Grandidierite is one of those hidden treasures in the world of gemstones, often prized by collectors for its sheer rarity. This mesmerizing stone boasts a unique blue-green hue reminiscent of a tropical ocean or glacier ice. Gemologists discovered Grandidierite in Madagascar in the early 20th century and named it after the French explorer Alfred Grandidier, who had studied the island’s natural history in depth. As one of the top ten rarest gemstones globally, any piece of jewelry featuring grandidierite becomes a true treasure!

EXCEPTIONAL RARITY: GRANDIDIERITE’S GEMOLOGICAL MYSTIQUE

Grandidierite, shimmering in its unique blue-green hue, is a beacon of rarity and luxury in the gemstone world. Securing its esteemed position at #3 on Forbes’ “12 Most Expensive Gemstones in the World” list, its value and scarcity are unmistakable.

The Gemological Institute of America (GIA) once reported that before the summer of 2015, coming across a grandidierite sizable enough to facet was “almost unheard of.” Its exceptional rarity is a significant factor in its price, with specimens with exceptional clarity fetching staggering prices per carat. Beyond its core worth, enthusiasts and connoisseurs celebrate and covet grandidierite as a collector’s stone. They recognize and seek it out as one of the absolute finest gems in the world.

Grandidierite is rare because there are very few places where we can find it. Miners use old-fashioned ways to get it out of the ground. They dig deep holes with tools like spades and pickaxes. The veins containing grandidierite don’t follow straight paths and often lack abundant gems. Miners manually extract the raw, uncut gemstones, collecting them little by little since each spot doesn’t yield much.

Its exclusivity enhances not only its market value but also its mystique in the world of gemology. When set into jewelry, grandidierite becomes an emblem of nature’s beauty and the luxury of owning something uncommon.

GRANDIDIERITE: A 100% NATURAL GEMSTONE

Nature masterfully forged grandidierite, a gemstone testament to the pure and unaltered processes deep within the Earth. This 100% natural gem, untouched by human interventions or synthetic enhancements, captures the essence of the planet’s ancient artistry. When you gaze upon its unique hue and patterns, you’re witnessing a beauty that artificial stones can’t emulate.

Owning such a gemstone means possessing a tangible, irreplaceable fragment of Earth’s vast history. Beyond its aesthetic appeal, the inherent value of grandidierite stems from its natural rarity and formation, establishing it not only as a radiant accessory but also as a sound investment for the discerning collector. Unlike gems subjected to treatments or enhancements, grandidierite promises longevity, ensuring its captivating allure remains undiminished across generations. When you adorn yourself with grandidierite jewelry, you’re not merely wearing a gemstone; you’re donning a piece of the planet’s legacy and showcasing the unparalleled artistry of nature itself.

GRANDIDIERITE  COLOR, CUT, CLARITY & CARAT

• Color:  Grandidierite is most famous for its captivating blue-green hue. The finest grandidierite exhibits a deep, translucent blue with greenish tones that remind one of the tropical oceans. Its color’s vibrancy can change under different lighting conditions, sometimes appearing more blue or green.

• Cut: Due to its rarity and the irregular shape of its rough forms, grandidierite often demands a custom cut. Cutting grandidierite can be challenging because of its cleavage and crystal orientation. A skilled gem cutter will orient the stone to maximize its mesmerizing color, often choosing elongated fancy shapes or ovals.

• Clarity: Top-quality grandidierite is almost transparent, with few to no inclusions. However, this level of clarity is quite rare. Many grandidierites have visible inclusions, but these inclusions often don’t detract from the stone’s beauty, given its dazzling color. In fact, they can sometimes add a unique character to the stone.

• Carat: Miners often find grandidierite in smaller sizes. Larger, high-quality specimens above a few carats are exceedingly rare and, thus, command higher prices. Given its scarcity, even smaller grandidierite gemstones with exceptional color and clarity can be quite valuable.

In the world of gemstones, grandidierite stands out with its unique combination of color, rarity, and the challenges it presents to gem cutters. It’s a testament to nature’s ability to create unparalleled beauty under the most unusual conditions.
