A fine modernist 18K yellow gold ring by Burle Marx set with an intricately carved amethyst in the “forma livre” (free form) style. Haroldo Burle Marx was particularly known for his use of large gemstones, often fashioned by carving or tumbling rather than faceting, a technique he invented in 1948.

The interior of the shank is signed “Burle Marx/750” and “Ind Bras/GB/791”.

An extraordinary modernist fringe necklace in 18K yellow gold and green tourmaline by the famed Brazilian modernist jeweler Haroldo Burle Marx. Burle Marx invented the technique of carving and tumbling forma livre ("free form") gemstones in 1948, and the technique became his signature. Most often, he used colorful stones native to Brazil—tourmalines, amethysts, aquamarines, citrines, etc. The tourmalines in this necklace are of the finest quality, with pure deep green coloring that contrasts beautifully with the gold mounting. Burle Marx never used pre-cast elements in his jewelry, and each piece was completely raised by hand from a gold ingot. All the plain gold links are accented with a brushed texture, and the links set with tourmalines have a contrasting florentined finish. The back of the clasp is stamped with Burle Marx's signature and 18K marks.

Acrostic jewelry spelling out such sentiments was very popular in the Victorian era. The gemstones are 19th century antique cuts and Tiffany apparently custom-set them in this piece at a client’s request. The nature of the clarity characteristics suggests that the ruby is Burmese in origin, while the sapphire is Kashmir. Neither shows evidence of treatment, nor are the emeralds filled. The “Tree of Life” pattern was often set with birthstones representing the owner’s children or grandchildren, but the acrostic “DEAREST” is most unusual.

An extraordinarily fine antique 18K yellow gold ring by Tiffany & Co. set with a mixed cushion cut Burmese blue sapphire surrounded by old mine cut diamonds. All the gems are of the finest quality. The sapphire has been certified by the American Gemological Laboratories (see the following paragraph). The diamonds, ranging in size from approximately .22 carat to .29 carat each, are estimated at G/H color and SI to VVS2 clarity. The sapphire is set in a prong setting, while the diamonds are set in a shared-prong setting that creates a filigree appearance around the back of the crown. The shoulders of the shank are lightly decorated with beaded engraving.

Nearly all sapphires marketed in the last 150 years have been heated to improve the color. This is considered a standard practice. Other treatments, such as filling in fractures, altering the color family, etc., though considered bad practice, are nonetheless quite common. Fine Burmese stones from the Mogok region that have not been treated in any way are exceedingly rare and only show up in upscale jewels from makers such as Tiffany and Cartier. This particular stone, with its bright coloring and beautiful cut, is nothing short of stunning.

The AGL Brief (dated April 2008) indicates that the sapphire is natural; displays specific properties and characteristics associated with stones from Burma; measures 7.39 x 6.69 x 5.82 mm; weighs 2.49 carats; is cut in mixed cushion, has blue color, and shows no heat or additional treatments. The brief further indicates that unheated sapphires are scarce. The original brief will accompany the ring.

Origin: America, ca. 1890. Condition: excellent, all original, interior of shank has a period monogram. Finger Size: 4-1/4 (The ring can be sized up and we would recommend that the work be performed by Tiffany). Weight: 6.0 grams. Gemstone Weight: diamond (estimated by measurement), 2.25 carats; sapphire (by actual weight), 2.49 carats.

A very nice 18K yellow gold Sputnik style ring by H Stern. The dome is bezel-set with round citrines, amethysts, green tourmalines, pink tourmalines, garnets and aquamarines. This design was created in the 1950s to highlight the range of colored gemstones available from the mines of the jeweler’s native Brazil. It later came to be known as “Sputnik” for its resemblance to the spiky Soviet satellite lanched in 1957. Each ring has a unique appearance that depends on the particular selection and placement of the gemstones. This example tends toward the pastel side with a fairly large number of aquamarines and lighter-toned amethysts. The shank is signed by Stern and is marked for 18K gold.

A very rare 18K yellow gold ring set with a black pearl designed by Jean Dinh Van for Pierre Cardin. The design has an overall trapezoidal shape.

Jean Dinh Van is one of the most important modernist French jewelers. He apprenticed at Cartier before starting his own studio in 1965.

The squared-off outline and simple placement of a single pearl is very typical of Dinh Van's work for Cardin, yet this is the first example we've seen of this design.
