Jewellery Investing - Hints and Tips

It may be tempting to think of jewellery as a safe haven of value. However, anyone considering jewellery as an investment needs to choose wisely.

The notion that jewellery retains its value is ingrained in cultures around the world with the implication that jewellery endures and retains its value over the long term.
The first caveat about jewellery is that if you buy new from a high end retailer, you will be losing from the start. The retailer usually imposes a 100% mark-up. Then there's the wholesaler's margin and the manufacturer's. You are also paying for marketing. Then there are taxes. If you sell the piece the next day you might get $.30 on the dollar. It might take many years to get back what you paid.
While brand-new jewellery fills a role in the market, wealth preservation isn't part of it. This general rule doesn't always apply to pieces designed by up-and-coming artists. To have any chance of acquiring jewellery that will be a good investment, you need to buy second-hand. Art Deco jewellery from 1920 to 1935, is worth considering. Anything signed by Cartier, Van Cleef and Arpels, Boucheron, Tiffany or similar will always be sought after because their pieces are of exceptional quality.

The worst possible 'investment' is jewellery containing lab created diamonds. There is virtually zero resale value for man-made diamonds.

Chrome Tourmaline

Chrome tourmaline is a special member of the tourmaline group. Found only in east Africa, it is usually found in small sizes. What it lacks in size it makes up for in color - it displays perhaps the richest, most intense green in the gemstone world.
There are similarities between chrome tourmaline and tsavorite garnet. They are found in the same locations in Tanzania, and both are colored by chromium and vanadium. Chrome tourmaline, in many ways, is equal to the finest tsavorite.

Chrome tourmaline is a distinct variety of tourmaline, called chrome dravite.
Like emerald and tsavorite garnet, fine chrome tourmaline is a pure forest green with slightly yellowish to bluish secondary hues. With a hardness of 7 to 7.5 on the Mohs scale and no cleavage, tourmalines of all types have good durability.

Generally, tourmalines are Type II clarity stones, showing inclusions. However, one can find eye clean green chrome tourmalines. Most would only buy chrome tourmaline graded IF (internally flawless) to VS (very small inclusions).

Amber is fossilized tree resin. It is organic not mineral. The oldest amber dates to the Upper Carboniferous Period, about 320 million years ago.

Scientists and collectors treasure amber that contains suspended animal or plant fragments. These fossilized parts of once-living things were trapped in the hardening amber, creating a time capsule.

Amber's warm luster is featured in beads, carvings, pendants, cabochons, as well as decorative items.

Transparent amber is more valuable than cloudy. A plant or animal inclusion adds greatly to the value of an amber specimen.
Peter the Great’s Amber Room near St Petersburg was made from six tons of amber. A Prussian gift in 1716, It was lost during WW II, but recreated in 2003.

The word amber means brownish yellow, but the gem can be yellow, golden, white, orange to reddish brown, or even bluish or greenish.
Cutting and polishing amber for jewelry makes it more susceptible to oxidation by removing or thinning the harder exterior surface. Fine translucent yellow or orange amber can gradually darken to reddish brown and eventually black.
