Conch pearls (pronounced KONK) are among the rarest and most valuable of all natural pearls. It has been estimated that approximately 15,000 conch must be harvested before a single pearl is found. An exceptional piece (pearls over 10 carats and exhibiting a strong chatoyant like flame pattern) may take as many as 50,000. Though pearls can be found in a variety of conch, it is the pearl from the Strombus Gigas or the Queen Conch, that has become the most widely known and collected. This is due in part to the wide variety of colors that it produces. Pearls can be found in colors of white, brown, beige, orange, pink and red, the latter two being the most highly prized. Finding a gem-quality conch pearl is known amongst fishermen as "the lotto". High prices are paid for such pearls, further adding to their allure. Over the last century, conch pearls have captured the attention of prestigious designers and jewelers alike. Conch pearls can be found in the world's most exclusive jewelry stores.

Sparkling with splendor of the sun itself, yellow diamonds are sure to usher happiness and joy into your life. The Contemporary Yellow Radiant Diamond Drop Earrings, made by Spectra Fine Jewelry in 2023, are crafted in 18K yellow gold and platinum and feature two outstanding radiant-cut yellow diamonds with an estimated weight of 12.78 carats total. The yellow diamonds are accompanied by a reort by Gemological Institute of America (GIA) stating they are natural diamonds of fancy yellow color with even distribution and VVS2 clarity with estimated carat weights of 6.63 and 6.15 carats, respectively. Fancy yellow diamonds are not only beautiful, but they are also rare and quite valuable - even more so at this large size. Approximately only 1 out of 16,500 carats that are mined is a yellow diamond, far more commonly in weights under 1 carat. This means that larger stones, which are much more rare, can be even more valuable than their colorless counterparts. It is not only the size of the diamond that makes it most challenging to match in a pair of earrings as symmetrical as these, but also the range of color that will vary with carat weight. Further, faceting changes the sparkle and nuances in color hue and saturation. The gemstones in these elegant drop earrings present visually as exquisite matches and as such, are a rare example of superlative curation and quality. The rectangular yellow diamonds...

These Spectra Fine Jewelry Illusion Asscher-shape Diamond Stud Earrings, made in the 21st century, suggest something much larger. Crafted in 18K white gold, the pair of earrings has an estimated diamond-carat weight of 10.74. The arresting pair has a look equivalent to colossal square emerald-cut diamond studs. Still, in fact, each is comprised of nine pie-cut diamonds, weighing an approximate total of 5.37 carats apiece. The earrings are designed for pierced ears and outfitted with posts and locking backs. Rounding out the rather spectacular diamond offering, each backing is decorated with a halo of sparkling round brilliant-cut diamonds, a lovely detail reserved for the wearer that will make putting on the earrings extra special every time. It is difficult to see that these significant studs are composed of much smaller cut-cornered square emerald cuts placed in the centers. They are surrounded by 8 meticulously matched step-cut diamond halos that fit together like puzzle pieces. Each of the 9-piece studs is mounted in a basket setting, the corners held with 8 strategically well-placed talon-shaped prongs. The shape of the prongs provides an added dash of luxury to the overall look. Talon claws or prongs are crafted based on the appearance of the talons of a bird of prey. They add a certain flair as they are typically used for large gemstones. If these studs were just one whole gem per ear, they would be exponentially more costly and rare than these clever trompe l’oeil composites. When setting gems in Art Deco jewelry of the 1920s and 1930s, a trompe l’oeil convention was popularly used as an effective optical illusion to make diamonds look larger or make rounds look square. The artful illusion was in the setting, generally, a larger custom-shaped bezel in which rounds were pavé-set; however, not in the composite placement of the stones. Therefore, the expert level of stone setting in these studs is a nod and variation of this design sensibility. Additionally, the earrings reference techniques from the Art Deco period, where custom geometric-cut gemstones were tightly set against one another to create a lush, jeweled...

These exquisite earrings feature a pair of pear-shaped diamonds, renowned for their graceful and tapered silhouette, making them the perfect choice for stunning drop earrings that capture attention with every graceful sway. The enchanting brilliance, scintillation, and fiery sparkle of these pear-shaped gems are brought to life through the skilled hands of an exceptionally knowledgeable diamantaire. This master craftsman is responsible for the meticulous cutting, polishing, and transformation of rough diamonds into the finished gemstones that adorn these exceptional earrings. The result is truly breathtaking when these well-cut diamonds are showcased in a simple and sophisticated design. Crafted in platinum and bearing the collaborative mark of Spectra Fine Jewelry and a legendary diamantaire, these earrings are a testament to exceptional quality and expert artistry. Four exquisite diamonds with an estimated total weight of 12.61 carats take center stage, boasting J color and VS1-SI1 clarity, as confirmed by reports from the Gemological Institute of America (GIA), which will be readily provided to interested buyers upon request. The platinum setting adds an estimated 10 grams of precious weight to these radiant gems. Designed for pierced ears, these earrings feature two pear-shaped diamonds, each weighing an estimated 5.53 and 5.54 carats, both of SI1 clarity. These pear shapes are exquisitely proportioned and infuse a touch of classic and feminine charm to any ensemble. The pear shape cut allows light to dance and play within the stones, creating a captivating spectacle. These four remarkable gems are securely cradled by platinum talon prongs that gracefully contour the sides of the diamonds, enhancing their natural beauty and maximizing the radiant play of light. Each diamond is a unique masterpiece, as distinct as a fingerprint with no identical match in the world. Pairing round and pear-shaped diamonds of this caliber demands an expert eye and years of experience to ensure the utmost symmetry in appearance. Achieving such a perfect match becomes even more challenging with larger stones...

If Cleopatra had played tennis, she might have chosen emeralds to adorn her bracelet. After all, emeralds—first discovered in ancient Egypt—symbolized fertility, power, and eternal youth. This platinum Spectra Fine Jewelry tennis bracelet channels that same timeless allure with 28 round Colombian emeralds totaling approximately 19.19 carats. The gems gently graduate toward the center, each set in a round basket with four talon prongs for a fluid, articulated feel. One emerald was tested by GIA and confirmed as natural Colombian origin with minor clarity enhancement. Designed with a minimalist spirit and a nod to the classic rivière style, this bracelet fastens with a concealed clasp for an uninterrupted, regal sparkle. Measures approx. 7" in length. 28 Colombian F1 emeralds...
