Amethysts in Ancient History


According to Greek mythology,  Dionysus, the god of fruitfulness and wine,  was angered by a woman named Amethystos.   Amethystos preferred the goddess Diana to Dionysus.   He sent two tigers to eat Amethystos. Diana rescued Amethystos by turning her into clear quartz (not much of a rescue!)  Dionysus was so sorry that he cried into his wine and then spilled it on the clear quartz, staining it purple and creating the first amethyst. 

The name amethyst is from the ancient Greek word "amethustos" which means "not drunk."    Because of the Dionysys myth, the Ancient Greeks thought that drinking from a vessel fashioned from amethyst would keep them from getting drunk.  They probably had a lot of fun testing that theory! 



In Exodus 28-19 in the Bible, the last gemstone in the third row of the High Priest's breastplate is thought to be amethyst by most scholars. 

In Hebrew, the name for amethyst is 'ahlamah' from the word halam meaning 'to dream.'   They thought wearing amethyst would give you good dreams.

In medieval times, amethyst was believed to keep your thoughts pure and make you more intelligent.

In the early Christian church, amethyst was also believed to have spiritual qualities and was part of a bishop's regalia.  The best quality amethyst is often called "bishop's grade."

New Jadeite Filter!

 


We did it! After tons of research and trial and error, we created our very own Jadeite filter.  We know there are other filters on the market, but we think ours is the best.  It gives really strong reactions that are easier to see than other jadeite filters. 


While filters alone are not a definitive test, they can be very helpful. They don't tell you what something IS, rather what something IS NOT.   By the way, there are bigger photos of the reactions on the website and I will be adding more. Please share your photos, too!

Filters can help distinguish between dyed and natural jade. 

They can also help quickly sort stones when buying a lot.  Say you are buying a lot of tsavorite garnet, you can use a filter to do a quick check to see if they are all at least giving you the same red reaction under the filter.  If they don't, that's a heads up that some of the stones maybe something else. In the example photo above, I added some green tourmaline to a lot of tsavorites. As you can see, under the filter the tsavorite reacts red, while the tourmalines are showing the blue of the filter.  Again, not a guarantee that the stones that react red are tsavorites, but at least you know the ones that don't, are not. Pretty cool, eh?

You can find the jadeite filter HERE.

Below are some photos showing the filter in use:







      Some Possible Jadeite Filter Reactions
      Natural Jade = Green
      Dyed Jade = Pink
      Tsavorite/Demantoid = Pink
      Alexandrite = Red

10 Fun Sapphire Facts for November

 


  1. Sapphires have been coveted and worn in jewelry for thousands of years in ancient Persia, the Roman Empire, and throughout the Middle Ages
  2. Sapphires come in a rainbow of colors! Including blues, yellows, orange, pinks, green.  Red corundum is called Ruby. Colors other than blue are called Fancy Sapphires.
  3. Sapphire (corundum) is one of the hardest minerals!  It ranks a 9 on the Mohs hardness scale.
  4. Blue sapphire gets its color from iron and titanium. Ruby gets its color from chromium.
  5. One of the rarest sapphires is a pinkish-orange color called padparadscha. The name is derived from a Sinhalese word for lotus flower. These gemstones can be found in the rivers in and around Sri Lanka
  6. The word Sapphire comes from the Greek word “Sapheiros“, and the Latin word “Saphirus” which means blue.
  7. Sapphires are often heat-treated to improve their color and clarities.
  8. The largest Sapphire ever cut is the Millennium Sapphire discovered in Madagascar, weighing an impressive 61,500 carats.
  9. Sapphires are Pleochroism stones. Meaning, viewing these stones from two different angles (like the top view and the side view), may produce two totally different colors; green in one view, blue in another.
  10. Blue Sapphire is the proper gift for these Wedding Anniversaries: 5th, 10th, 12th, 16th (Star Sapphire), 45th, and the 85th Wedding Anniversaries.
  11.  Some of the best sapphires are mined in Kashmir, Burma, and Sri Lanka (Ceylonese).
  12. The most famous sapphire ring today is the royal sapphire ring given by Prince Charles to Lady Diana Spencer in 1981. Princess Catherine now wears the ring. The ring possesses a 12-carat oval blue sapphire and is surrounded by diamonds.

New Take on Diamond Ring!

 diamond ring
Diamond ring made entirely of diamond!

see the full story here: https://9to5mac.com/2018/11/12/jony-ive-diamond-ring

"Sir Jony Ive, Apple’s Chief Design Officer, and renowned industrial designer Marc Newson – having curated the (RED) auction five years ago – have, this year, designed a unique ring, made exclusively for (RED) by Diamond Foundry®. Consistent with their mutual obsession with transforming raw material into objects of value, Ive & Newson’s design is singular, clear and un-compromised by the traditional metal settings and bands that have previously been required to create ‘diamond rings’. Theirs will be created by removing material rather than adding – an ambition made possible by the extraordinary scale of the stone which will enable the ring to be completely made of this material.

Creating a ring-shaped diamond is no small feat; the diamond block will be faceted with several thousand facets, some of which are as small as several hundred micrometers. The interior ring will be cylindrically cut out for the desired smoothness using a micrometer thick water jet inside which a laser beam is cast. The finished ring will have between 2000-3000 facets which has never been seen before on a single piece.

The gemstone will be created by Diamond Foundry®, the certified carbon neutral diamond producer who has pioneered and developed the proprietary technology to form diamonds safely and sustainably."
