The Fall NJ Gem Show starts on Wednesday October 8th and the excitement around the venue in Edison, NJ is starting to grow. Gem lovers from around the world will gather at the NJ Convention & Expo Center and explore a gigantic selection of gems, fossils, jewelry and more from vendors from around the globe. Here are some unique gems we’re excited to see at the gem show this week.
Alexandrite
Often called the “emerald by day and ruby by night,” alexandrite is famous for its remarkable color-changing ability. In natural light, it appears a vivid green or bluish-green, while under incandescent light, it shifts to shades of red or purplish-red. This optical phenomenon, known as pleochroism, makes alexandrite a gemstone of mystery. Its dramatic transformation symbolizes adaptability and balance that makes it appealing to gem collectors. High-quality alexandrite is exceptionally rare, and spotting one at the Fall NJ Gem Show is a true treat.
Tanzanite
Tanzanite is one of the most captivating gemstones on the market today, known for its deep blue-violet hues that shift in tone depending on lighting and angle. Discovered in Tanzania in the 1960s, it remains a single-source gemstone found only in the foothills of Mount Kilimanjaro. Its rarity and vibrant color make it a favorite among gem collectors and jewelry designers alike. Tanzanite’s mesmerizing color variations—from sapphire blue to violet and even hints of burgundy—set it apart as one of the most unique stones featured at the show.
Tourmaline
Tourmaline stands out as one of the most diverse gemstones due to its broad range of colors—from bright pinks and lush greens to deep blues and even multi-colored varieties known as “watermelon tourmaline.” Each stone forms under unique geological conditions, resulting in stunning color combinations that make every piece distinctive. Its versatility and vibrant appearance make it a favorite among jewelry artists who want to showcase creativity through natural color.
Sapphire
Most people associate sapphire with a rich royal blue, but this gem actually comes in nearly every color of the rainbow except red. Each hue carries its own charm and character. Blue sapphires symbolize loyalty and truth, while pink and yellow sapphires bring warmth and positivity. Known for their hardness and brilliance, sapphires are both durable and timeless—ideal for fine jewelry and heirloom pieces.
