Ivory Ban Enforcement Date Coming Soon (June 30, 2017)


With the signing of Senate Bill 2647, Hawai‘i passed the most comprehensive U.S. state law targeting illegal wildlife trade.

The law was passed by the Legislature in June 2016 and its effective date is June 30, 2017.  Individuals and businesses with wildlife products in their possession only have until June 29, 2017 to lawfully dispossess of the items (sale, gift, or transfer). After that it will generally be illegal to sell ivory (and other covered items) within or from the Sate of Hawaii. The law does provide some exemptions for bona fide antiques, musical instruments, guns and knives, and traditional cultural practices.

Private possession of ivory that was legally acquired remains legal, even though ivory commerce will be generally prohibited effective June 30, 2017. For elephant  ivory to have been legally acquired it generally must have been imported prior to Federal bans beginning in 1975. Retailers should be careful not to display private collections of ivory as the bill includes a presumption of intent to sell clause.

HJA is in constant communication with the Honolulu Police Department regarding any crimes that we gain knowledge about.

HJA is in constant communication with the Honolulu Police Department regarding any crimes that we gain knowledge about.

We have been in collaboration with HPD to discuss the recent increase in local burglaries in order to keep our businesses and community informed.

"The Honolulu Police Department encourages any persons, or entities that are the victims of crimes to report these incidents immediately.  At present we have not identified any patterns indicating a significant rise in crimes perpetrated against jewelry retail establishments, but if these types of crimes are going unreported we may not be able to focus the appropriate resources to address these problems.  It is the Honolulu Police Department’s policy to not disclose specifics of a crime outside of departmental channels unless it is with the consent of the business owner."

Honolulu Jewelry Company creates a big birthday surprise for Wish Child, Shor

This wish was sponsored by Jeweler’s for Children, an international organization dedicated to uniting charitable giving efforts within the jewelry industry to children in need. Make-A-Wish has benefitted from this organization on a national and international level, and on a local collaboration with nonprofit Hawaii Jewelers Association (HJA).

HJA members volunteer by hosting wish celebrations for local kids whose wishes are sponsored by Jewelers for Children. HJA-member Honolulu Jewelry Co. allowed Shore and her siblings to tour the entire facility and gifted her a custom Hawaiian heirloom pendant necklace with her name on it. They watched the bench jeweler engrave an additional surfboard upon her request.

HJA members like Honolulu Jewelry Co. who participate in wish celebrations provide these kids with educational insight into their day-to-day operations by showing jewelry pieces, gemstones, diamonds, and machinery needed for production. At these events, wish kids are gifted a memorable piece of jewelry to serve as tokens of their wish journeys.

The Minute Hand 1:03

The Minute Hand

Welcome to our ongoing series of short articles about watches which should only take a minute or two to read. We continue today with a brief discussion of watch crystals.

Watch Crystals

The crystal on a watch is the "glass" that covers the dial and hands.

There are basically 3 types of crystals used on watches these days. And really, only 2 of them are commonly used anymore.

  • Mineral Crystal - which is a fancy way of saying hardened glass. Even though hardened, it can be scratched by things like steel and brick so you should avoid scraping a mineral crystal against things. Advantages: low cost and better impact resistance than sapphire. Disadvantages: scratches somewhat easily and cannot be repaired (typically replaced if damaged).
  • Sapphire Crystals - man made, synthetic sapphire. They are chemically and structurally the same as  natural rubies and sapphires - all of which are corundum, an aluminium oxide. If a sapphire is red in color, it is a ruby. Otherwise any other color (including colorless as is used on watch crystals) is called a sapphire. So while we often think of sapphires as only being blue, this is not always the case.  The jewels in a watch movement are typically man-made rubies. So outside of their red color, they are the same material as a watch's transparent sapphire crystal over the dial and hands. Advantages: very hard (9 on the Mohs scale - where diamond is 10). Disadvantages: more costly than mineral crystal (glass) and it can be chipped or shattered more easily than hardened glass. One chipped, it can not be repaired (only replaced).
  • Plexiglass - an acrylic  plastic. A particular brand of plexiglass known as "Hesalite" has been used by Omega on their famous Speedmaster chronographs since they went to the moon with the Apollo astronauts Neil Armstrong and Buzz Aldrin in 1969. While it is possible to buy a new Speedmaster today with a plexiglass crystal, most new Speedmasters have sapphire crystals. Plexiglass has been used for watch crystals since the 1950s and is highly impact resistant. You can beat on a piece of plexiglass with a hammer and while you will no doubt deeply scratch it, it is extremely tough and shatter resistant. Even with normal use (no hammering), scratches are common on plexiglass crystals. However, using abrasives many scratches can be polished/buffed out. Advantages: low cost compared to sapphire and virtually unbreakable. Disadvantages: scratches very easily and is not as transparent as mineral crystal or sapphire.

Crystals may be flat or domed (curved). If a crystal is only domed on one side, it will act as a magnifier and will distort your view of the dial and hands. A double domed (curved top and bottom) crystal avoids distortion while still having a pleasing domed appearance and feel.

Anti-reflective (A/R) coating are often (but not always) applied to a watch crystal to help minimize unwanted reflections that make it harder to read the time. If applied to just one side, it will be coated on the bottom (inside) surface where it will avoid being scratched. A doubled coated crystal has A/R coating on both the top and bottom surfaces of a crystal. This does a better job of eliminating reflections but the top coating may be scratched as the coasting is not nearly as hard as the sapphire crystal upon which it is usually applied.

"Flame Fusion" is a marketing term used by low end watch brand Invicta for some of their crystals. This appears to just be a thin layer of sapphire applied on top of a piece of mineral glass. It is generally considered to be a low cost, inferior product compared to a true sapphire crystal.

Another, historically interesting, crystal material was a piece of natural quartz which was used on the famous "Marie Antoinette" watch made by Abraham-Louis Breguet (the most famous watchmaker of all time). This is probably the most famous watch of all and was not even completed during the lifetimes of either Marie Antoinette or Breguet. To read more about this fascinating watch, pick up a copy of the book  "Marie Antoinette's Watch" by John Biggs -  Available on Amazon.

Times up! That's all for today. Stay tuned to the Hawaii Jewelers Association website for the next installment of "The Minute Hand" with your host, Mark Carson of Mark Carson / Individual Design watches.
