Gemstones accompany the four seasons with their everlasting brilliance and color. They are particularly striking as solitaires and in the form of purist pendant earrings. A single gemstone, cut from a transparent crystal, defines a "Clear Crystal" earring by Thomas Jirgens.

As early as March, gemstones capture the spring awakening, their vibrant colors aligning with the blossoming of nature. Green prasiolite is reminiscent of fresh grass, yellow citrine shines like the first warming rays of sunshine or forsythia blossoms, and violet amethyst glows like crocuses or lilacs. Delicate rose quartz crystals dance like cherry blossoms on the wearer's ears like a never-fading spring bouquet. Carefully selected aquamarines, cut into dramatically large pairs in architectural shapes, perpetuate the vibrancy of summer. Their soft shades of green-blue tell of the mystique of crystal clear water in sunlight, and go especially well with blue and green eyes. These aquatic colors are a perfect accompaniment for the intense, bright light of any summer day, but are also wonderful companions on balmy evenings and at night. In the fall and winter months, smoky quartz in all its golden-brown hues caresses the face like a fine cashmere coat. The softer sunlight interacts well with these warm colors and is especially flattering to the complexion. When the gemstones' earthy shades accentuate the color of the eyes, purest harmony ensues.

Tailoring the cut of a single crystal to a woman's face, thus making it resonate like a well-chosen frame for a painting, elevates her face with the jewelry to a holistic piece of art.
