Jewelry Appraisal

If you are a frequent reader of our blog you may already know that October’s birthstone is opal. In honor of this beautiful gemstone San Francisco’s Bonhams and Butterfields will be holding an auction devoted to opal. This auction will be among the first held in the U.S and the first of its kind at Bonhams and Butterfields. The auction will feature a diverse group of high quality and distinctive jewelry, unmounted stones, mineral specimens, lapidary works of art, decorative objects, decor and opalized fossils, made from the opulent gem. Many of these pieces will highlight opals unique ability to seemingly hold fire, water and air in the stone itself.

Possibly the most unique and expensive item on the auction block will be a opal hat called “The Deep Blue Sea”. Estimated at $200,00, this piece is made from hand-blocked Australian felt, adjourned with feathers and has 26 opals weighing approximately 1,447 carats! A partnership between Australian master milliner Ann Maree Willett, opal miners Vicki and Peter Drackett and opal carvers Daniela L’Abbate and Christine Roussel, resulted in the creation of this one of a kind hat.

Some other exceptional items that will be auctioned off are a opal and 18kt gold presentation box set with large 224.24-carat oval cabochon of white opal, estimated at $100,000- 150,00. There will be a 34.80-carat Boulder opal and briolette diamond necklace, estimated at $90,000 – 110,000 and a Mexican Fire Opal and diamond necklace, mounted in 18K yellow gold, comprised of 40 opal cabochons and 11.3-carats of diamonds, estimated at$20,000- 30,000, with a matching pair of earrings.

O is for October and Opal!

With the month of October now underway today I am bringing you a brief lesson in Gemology.  Since the birthstones (that’s right there are two!) for October are Opal and Tourmaline.  While this article is focused mainly on Opal I will follow up with a second article about Tourmaline shortly.  Opals were revered by the ancient Romans as it was inspiring to them for its beauty was almost impossible to describe in words.  Romans simply called it “Opalus” a word that means “precious stone”.  One philosopher and scholar Pliny described opals as “they equal the deepest and richest colors of painters. Others simulate the flaming fire of burning sulphur…and even the bright blaze of burning oil”.  He was referring to Opals play of color ranging in colors as blue/green such as peacock feathers and vibrant reds and oranges like hot magma shooting out into the sky from a volcano.

One of the greatest things about opal is that the range in varieties and colors make opal such a versatile stone.   It ranges in color and qualities from the modestly priced white opals with a milky base color and soft play of color to intensely vivid black opals with color so intense it can look like it is on fire.    The patterns of the opal’s play of color can be categorized in one of three types; Pinfire, Flash and Harlequin.  Pinfire displays very small patches or “dots” of play of color, Flash displays large areas of play-of-color and Harlequin shows large, distinct angular patches of play-of-color with edges touching each other.

Opals are found all over the world.  White opals are the most common and are found in Ethiopia, Australia, and North and South America.  Fire opals known for having their intense orange and red colors are most widely found in Mexico.  Black opals are found almost exclusively in Australia.   One of the main mining areas in Australia is Coober Pedy.  The name comes from the aboriginal word “kupapiti” which literally means “white man in a hole”.  Because of the hot nature of the Australian outback miners there often live in underground housing to escape the heat.

With the current resurgence of victorian and vintage style jewelery designs, one cannot ignore the importance of opals in todays market.  Usually opal jewelry is offered at a commercial level with small white opals and low play of color but finer quality opals are beyond beautiful.  They have a rich glow to them that cannot be compared to by any other  gem.  At Raymond Lee Jewelers we have a wide selection of opal jewelry of fine quality.  Come in today to see our selection!.

Jewelry Terminology: Opal

Opal from Yowah, Queensland, Australia.

Opal

In jewelry terminology, the word Opal is derived from the Latin word opalus, meaning “seeing jewel”.

Opal is a fine gem that has seen its popularity rise and fall over the decades. In it’s most recognizable form, it tends to resembles the earth as seen from outer space, an array of blue-green swirls punctuated by random otherworldly flashes of color. Opal is unique in that it has practically unlimited variations. The one characteristics all its variations share is that they all shine and sparkle in a continually changing play of colors which is called “opalising”. Opals are differentiated by the kind, place of occurrence, and color of the main body. There are Dark or Black Opals, White or Light Opals, Milk or Crystal Opals, Boulder Opals, Opal Matrix, Mexican Opals called Fire Opal, these are only a few common variations. Opals that lack the characteristic flashing of colors are referred to as Common Opals.

One reason why the Opal has had diminishing popularity in the past is due to its composition. Opal is a living stone that actually has water within it. This water can cause the Opal to suffer from instability and crack, a process known as crazing. Due to this it is best to not place an Opal where you would not put your skin, extreme heat or cold. Also Opal is considered one of the most difficult stones to value.  Unlike Diamonds who are evaluated using the four C’s: cut, clarity, color and carat weight, the Opal goes well beyond these terms. Some factors that play into determining its worth are if the Opal has recognizable patterns, how thick its color bar is or if it can be domed.

Over time these problems have become less significant and Opals popularity has started to rise as a result. Many collections now include Opals, often times set in simple pieces or accompanied with pearls.
