    Known as canary diamonds, yellow diamonds are the most coveted among the fancy colored variety. Named after the small songbird, these diamonds have a rich yellow hue. They get this unique color from the small nitrogen components in their structure.

It is set with a 16.07-carat cut-cornered rectangular modified brilliant-cut diamond, flanked by two trillion-cut diamonds. Another noteworthy ring is a GRS-certified Mozambique ruby and diamond cocktail ring. Crafted with a cushion faceted Mozambique ruby and round brilliant-cut diamonds, the ring is fashioned in 18-karat white gold.

Designed with 18-karat yellow gold and platinum prongs, it is crafted with square-faceted rubies. Schlumberger is acclaimed for designing such whimsical, nature-inspired creations.  An Art Deco bracelet crafted in platinum also leads the listings.

    Pigeon’s Blood Burmese Ruby Earrings and Untreated Zambian Emerald Ring Highlight Fortuna Auction’s Upcoming Sale

    The people of Myanmar, formerly Burma, use the term “ko-twe” (pigeon’s blood) to refer to the most sought-after color of ruby. This blood red variety resembles the hue of a pigeon's blood and eyes. Some also liken it to the shade of pomegranate seeds. Prized for its rarity, the blood red ruby signifies warmth and sensuality and is closely associated with royal status. A pair of helix drop earrings studded with pigeon’s blood Burmese rubies and diamonds is a key highlight of Fortuna Auction’s upcoming sale. The 18-karat white and yellow gold earrings are crafted with four unheated Burmese rubies, together weighing approximately 3.30 carats. The pieces are also accented with marquise-shaped rose-cut diamonds and round-cut rubies.  Another rare piece is a cocktail ring designed with a 3.38-carat untreated Zambian emerald and diamonds. A no-oil emerald is highly coveted for its lucidity, which is purely natural and not artificially augmented. The sale also offers a Rolex stainless steel GMT-Master wristwatch. Rolex originally produced the model in alliance with Pan American Airways in 1955. The airline then issued the watches to their crew members on long-haul flights.

    Jewels & Watches

    Henri Rodanet (1884-1956), the descendant of a family of Parisian watchmakers, joined Jaeger LeCoultre after World War I. At the time, small wristwatches were beginning to be marketed toward women. The duo wanted to make small size lady’s watches without compromising on quality. Rodanet brainstormed the idea and came up with an innovative double-sided watch movement for the Calibre 101. LeCoultre's Calibre 101 debuted in 1929 and became world-famous in 1953 when Queen Elizabeth famously wore one of these watches on her coronation day. Fortuna Auction will present one of these LeCoultre watches from the 1930s in the upcoming sale. The available piece is modeled as a continuous line bracelet, each link set with a single white diamond and a tiny watch dial set in a square window. Among the offered 205 lots, a vintage long Alhambra necklace from Van Cleef & Arpels is particularly highlighted. Unveiled in 1968, the Alhambra motif was inspired by the four-leaf clover and is considered reminiscent of the traditional quatrefoil. Also showcased is a Gikas lapis lazuli set. This vintage 18-karat gold set includes a bracelet, earrings, and necklace. Explore the full listings and register to bid online on Bidsquare.

    March Fine Jewels

    Available in the upcoming March Fine Jewels auction, offered by Fortuna Auction, is a 4.95-carat diamond ring. Set in platinum, the piece features a pear brilliant-cut diamond and two tapered baguette-cut diamonds. Included with the lot is a GIA report stating the gem’s D color and VVS1 clarity. According to the American Gem Society, clarity grades of 1 or 2 fall in the category of “very, very slightly included.” This means that the diamond has “... minute [imperfections] that are difficult for a skilled grader to see under 10x magnification.”  Another highlighted lot is a diamond, opal, and sapphire necklace, set in platinum and gold. The cabochon-cut black opal is an uncommon variation of the stone, almost exclusively mined in the Australian town of Lightning Ridge. Due to traces of iron oxide and carbon elements, black opals tend to have darker and more vibrant colors as compared to regular opals. Shades of coral, yellow, blue, bright green and purple can all be seen in the available piece. Below the opal is a lozenge-shaped sapphire weighing approximately 2.60 carats. Flanking the sapphire are two half-moon step-cut diamonds.  Also featured is a sapphire and diamond ring from Van Cleef & Arpels. The central sapphire in this piece weighs approximately 9.0 carats and is accented by round brilliant- and baguette-cut diamonds. A Cartier Egyptian Revival diamond cuff will be presented, showing a falcon with its wings extended. The bird is detailed with round diamonds. Rounding out the sale are several emerald pieces from Orianne, including a statement necklace, a set of earrings, and an emerald and diamond bracelet.

The diamond is placed in an 18-karat white gold ring and is flanked by two smaller diamonds. Another ring presented in the sale comes from the Harry Winston jewelry house.
