Alexandrite- A Scarce Color-Change Birthstone

Back to top

One of the most often asked questions is about the June birthstone- Alexandrite.  Genuine Alexandrite, a color-change stone, is a scarce and expensive gemstone in a good quality.  It is only occasionally offered in mothers jewelry.  As with all genuine stones, Alexandrite comes in different qualities and price ranges that are generally based upon the color and color-change phenomenon, the cut and  the clarity of the stone.

Because of the price and availability problems associated with genuine Alexandrite, some mfrs. have selected their own genuine stone to represent the month of June.  Some manufacturers use Green Tourmaline to represent the green color of Alexandrite... another offers Color-Change Garnet because it too changes color based upon the light source. Others offer Smokey Quartz... and still others use Pink Tourmaline. These stones are offered by the mfrs. to help keep the price of their products affordable.  If you must have genuine Alexandrite, we recommend the collection below.  Note that stones have only limited availability and finer qualities may also be available (pricing is for "A Quality" Alexandrite).

"Commercial Grade" means a lower quality of genuine stone which is most noticeable in Emeralds, Rubies and Sapphires. Other stones tend to be more acceptable in their appearance.  We offer a few collections that only offer commercial quality stones and the ratings we give them is usually a 3 (+/-) heart rating. 

Two important things determine a commercial grade stone...
Color: Emeralds may be very pale or very dark.  Rubies may be pinkish to purplish red. Sapphires are usually "inky" or very dark blue/black with no royal blue flash.
Inclusions:  Most commercial stones will have numerous inclusions that prohibit light from traveling past the table or top of the stone.  Only the top facets of the stone may reflect light so the stone appears "cloudy" with little sparkle.
 

Inclusions are a natural occurrence in genuine stones but especially noted in Emeralds.  You will find inclusions in most genuine stones.  We do not offer eye-clean stones, stones with no eye visible inclusions, like those shown on the "clear" side of the picture on the left. When searching for the mother's jewelry collection that is right for you, you want to find a balance between price and eye-visible inclusions (meaning inclusions visible with the naked eye or without any magnification).  When you have a stone that has fewer inclusions, light is able to pass through the table of the stone to reflect off the facets inside the stone.  It gives the stone more depth and sparkle.  With Commercial Quality or Commercial Grade stones, the light may only reflect off the top of the stone or there may be numerous inclusions that make the stone completely impenetrable by light. For the best quality emeralds and rubies that we offer, we recommend  collections with a 5 heart rating and look for stone qualities finer than "A".  Good qualities are also found in collections with 4 heart ratings.  Stones will still have inclusions however they will have a better overall appearance.

What is the difference between genuine, synthetic and simulated stones?

Back to top

Genuine Stones: Genuine stones come from the earth and have been created by God/Nature.  Many genuine stones are commonly treated by man to either bring about or enhance their beauty.  Some stones are rather unattractive until they have been treated.
Synthetic Stones: Synthetic stones are man-made or created stones that have approximately the same chemical and physical characteristics of genuine stones.  They are created in a laboratory by man.
Simulated Stones: These are stones that only look similar to a genuine stone... they imitate a genuine stone.  Note that simulated stones seldom look the same as genuine stones.
 

How do I properly care for specific gemstones?

Back to top

The type of gemstones you have or select determines the care they require. Some genuine stones have excellent durability while others require you to be more careful when wearing them.  For instance rubies and sapphires are considered an excellent choice for everyday wear while an opal or pearl require extra careful handling.  This is NOT to say that you can be rough or abusive with your jewelry.  You can break any stone including a diamond.  It simply means that some gemstones are more durable than others.  For a list of details about several varieties of genuine stones, please visit one of our manufacturer's websites at http://www.stuller.com/kb/article.aspx?id=10621

What happens if we have a new addition to our family and we would like to add stones in the future?

Back to top

IMPORTANT: Some of our manufacturer's do NOT offer a stone  addition or trade-in option!  Be sure to visit and read the "Product Information Page" located on each individual product page.

Many of our mother's and family rings, pendants, etc. can have stones "added" at a later date for an additional charge plus shipping as long as the design is still available.  Contact us for current pricing for this service- include style number, whether genuine or simulated stones are set, the number of stones in the ring you currently have and the new stone addition(s) required. Your existing ring is most often traded in for a new one with the new stone additions... you do not get your old ring back. One exception is the Original Mother's Ring®... this ring usually has new heads soldered in place for the new stone additions (note that existing stones must usually be removed and reset except for diamonds, rubies or sapphires because they will not take the heat.  See each product page for the maximum number of stones possible for that particular style. 

Note that the Original Mother's Ring is more expensive to add new stones to... this is one ring where the original setting is usually returned with new stones added.  See the product information page for The Original Mother's ring for important details before ordering.
