On November 18, Canadian auction house Dupuis will offer for bids an extraordinary collection of jewelry, from bejeweled rings and necklaces to watches and jewelry cases. The elegant designs are sourced from some of the finest jewelry houses in the world, including Cartier, Rolex, Bulgari, Buccellati, Tiffany, De Beers, Van Cleef & Arpels and Chopard.

The exquisite looks range from vintage to modern and offer a glittering array of gemstones and materials, such as opal, South Sea pearls, pink tourmaline, lapis lazuli, sapphires and Colombian emeralds. Here are our picks that are not to be missed:

This diamond and platinum ring boasts a 10-carat emerald with a band embedded with round diamonds. The emerald cut is cut with 58 facets to enhance the radiance of the stone. However, this design did not become known as the "emerald cut," named as such because emeralds were typically fashioned in this shape, until the 1920s, when this simple, yet brilliant look became popular as part of the Art Deco era.
Estimated $109,200 — 124,800

This Cartier brooch is set in a floral shape with a 1.05 carat diamond at the center surrounded by six baguette-cut diamonds, three pave-set leaves, and three clusters of three ruby florets totaling five carats, all set in 18k gold. Cartier was founded in 1847 by Louis Cartier and was referred to by King Edward III as "the jeweler of kings and the king of jewelers."
Estimated $11,700 — 19,500

This diamond and gold necklace by Van Cleef & Arpels is a convertible piece made of four seven-inch segments that can also become bracelets. The design is made of 18k gold and the oval links are studded with diamonds. Van Cleef & Arpels is a Parisian jeweler that was founded by Alfred Van Cleef and his father-in-law Salomon Arpels in 1896.
Estimated $20,280 — 28,080 

This elaborate Edwardian era brooch (c. 1910) is centered on a 2.35-carat diamond, surrounded by six sapphires weighing 4.35 carats. The outer scalloped edges are comprised of smaller diamonds punctuated by pear-shaped diamonds, totaling 2.45 carats, and all is set in platinum and 18k gold. The Edwardian era covered the reign of King Edward VII from 1901-1910 and is remembered as a relatively peaceful and prosperous era that emphasized art, fashion and high society, a milieu that quickly came to an end with World War I.
Estimated $9,360 — 12,480
