EMERALD

Emerald is considered to be among the most important colored gemstones because of its tradition and universal acceptance. Since the time of Cleopatra, the emerald has been admired for its lively and characteristic green color. From light to dark shades, from transparent to translucent, almost always with visible natural inclusions, each polished emerald glows with its unique beauty and personality. Amsterdam Sauer is proud to have discovered the first Brazilian emeralds in 1963, thence becoming the leading specialist in South America with a direct supply from the mines, including Colombian emeralds.

IMPERIAL TOPAZ

The official royal gemstone from the time of the Russian Czarinas, the imperial topaz is currently mined only in Brazil, with very limited supply, hence its rarity. The bright transparent faceted gems come in a variety of astonishing colors – from honey-yellow, orange, salmon and pink to the prized sherry-red or cognac color. Imperial topaz jewelry has become a must for connoisseurs and collectors of rare and fine jewelry.

TOURMALINE

A very traditional Brazilian gem, the tourmaline group is polychromatic and possesses great beauty. The green-colored variety is known as green tourmaline, or simply as tourmaline; the red and pink varieties are the rubellite and the pink tourmaline; the blue is the indicolite. There are many other colors and combinations with different intensities, each one with its own personality, giving the Amsterdam Sauer designers an infinite opportunity to create stunning jewelry.

PARAIBA TOURMALINE

Although it belongs to the tourmaline group, the Paraiba tourmaline deserves its own section. A very young gemstone, it was only discovered in the 1980s, and quickly achieved worldwide recognition. The unique, hypnotic “neon” or “electric” effect of its greenish-blue color caused a wave of interest all over the world. Its highest-quality forms are extremely rare since it is only produced in Brazil and Mozambique, in very limited quantities. Possessing a Paraiba tourmaline jewel is the privilege of few.

AQUAMARINE

The most traditional Brazilian gemstone, aquamarine has a soft crystalline blue color with an overcast of green, imparting elegance and delicateness in exquisite jewels. The color comes in pastel shades; hence, the darker the stone, the rarer it is. Over its seven decades of existence, Amsterdam Sauer has become specialized in large faceted gems used in high-quality jewelry.

OPAL

Play of color is the rare gemological phenomenon that makes a common opal become a precious gem. These intriguing flashes of rainbow colors displayed in a mosaic pattern within the cabochon cut are unique to each gemstone; thus, each stone is one of a kind, just like a fingerprint. Opals symbolized hope, innocence and purity to the Greeks and Romans in ancient times. Australia, Brazil and Ethiopia are the main sources of precious opals. New fashion trends have recognized opal jewelry as contemporary.

TANZANITE

A single-source gemstone, tanzanite was discovered in Tanzania in 1967. It is unmatched in beauty, possessing a bright, transparent, purplish-blue color. Amsterdam Sauer was the first South American jeweler to promote this rare gemstone. Fine-quality, deep-blue tanzanite must be properly cut to display the right amount of purple when mounted in jewelry. Light violet hues are also beautiful, and are more abundant.

BLUE TOPAZ

The bright celestial to deep ocean colors of the blue variety of topaz have crowned this gemstone as one of the most popular and affordable, thanks to new technologies for permanent and safe color enhancement. Blue topaz exists in different shapes and sizes, allowing for an infinite array of modern jewelry design.

AMETHYST

Amethyst is the oldest transparent gemstone worn by man, with records dating back 25,000 years. From the rarer deep purple to the soft lavender “Rose de France”, amethyst is among the most popular gemstones. Large fine amethysts are commonly used in high-quality jewelry. Brazil is the main source of amethyst.

CITRINE

The bright, intense golden yellow and the deep brownish-red colors are the signature qualities of finest-quality transparent citrines. Lighter hues are also very beautiful and abundantly used for more affordable jewelry. Both amethyst and citrine are the noblest varieties of the quartz mineral, and exist in different shapes and sizes. The main source of citrine is Brazil.

DIAMOND

A universal symbol of love and eternity, the diamond leads the world of gemstones and jewelry. Produced in many regions of the world, including Brazil, it is present in almost all fine jewelry, either as the main stone or as an adornment for colored gemstones. The quality of the cut of a faceted diamond is of the utmost importance to reveal the beauty and maximum potential of this crystal. The exclusive round-cut Amsterdam Sauer Legacy Diamond has incomparable beauty, as a result of the luminosity transmitted by its ideal proportions and its 82 facets.

The Amsterdam Sauer diamonds are purchased from the countries participating in the Kimberly Process Certification Scheme (KPCS), which determines a strict control on the extraction, import and export of diamonds according to international patterns of responsibility and integrity.
