The Romans brought examples of blue and green spinel into England, during their occupation, which date back to 51 B. The actual mining of spinel began in Afghanistan between and A. Red spinels have always been favored and have the most dramatic history. In Moscow, a Red spinels were used frequently in the Renaissance and became quite fashionable in the 18th Century.
The largest collection of spinels, which includes a carat gem, is part of the collection of the Royal Crown Jewels of Iran. Spinel is a mineral group that produces some of the finest gemstones , yet it has never been accepted by the general public as a valuable adornment due to poor marketing. It has a hardness that is equal to topaz and is very durable. In antique jewelry, one will hardly ever encounter spinel although the jewelers from days gone by may have used them as rubies or sapphires.
One will for that reason not find many spinels in antique jewelry from the Georgian period hitherto although spinel is gaining in popularity in present times. The different optical and physical properties should pose little problems for an experienced gemologist to distinguish between them.
Couples should reject Spinels in which inclusions are obvious, as they negatively impact the value and beauty of the gem. Common Spinel inclusions across all colors are fingerprints partially healed crystal fractures and crystals.
Some Spinels get their coloration from iron, like mine. I know this because I can see a small iron-oxide rust! Natural inclusions like these are the birthmarks of your stone — they prove the natural origin and lack of heat treatment! One of the unique characteristics about Spinel is its lack of heat treatment. Unlike many perhaps most other gemstones, Spinel is not routinely given any treatment to enhance its beauty. Instead, crystals are simply mined and faceted. So, should you encounter a gem that has received heat, or any other treatment , you should pass.
All gemstones weigh differently for their size. So, a 2. This is because they each possess a different specific gravity. Instead, I suggest you slap a ruler on your finger and see what size stone you want! I wanted a gem that was at least 7. That translated to a 2. It will be different for every stone, so measurements are the easiest way to get exactly what you want.
Finally, make sure that you purchase from a reputable seller that really knows their stones. Most Spinel is not certified the way Diamonds are. Therefore, couples must be able to trust their seller. While the mainstream popularity of Natural Spinel is rising, it is still not a commonly sold gem. Because of its similarity in color and appearance, Lab-made Spinel has been used for decades to mimic gems like Ruby and Sapphire.
This ensures that your gem will stay beautiful for a lifetime. Those that choose delicate, less protective mountings should take their gems off before any vigorous activity. Cool-colored gems, like blue and violet, look best in white metals like white gold, palladium, or platinum. Warm-colored gems, like red and pink, look great in yellow, rose, and white metal!
