Gift Ideas for the Holiday Season
We receive a lot of email at this time of year asking us for gift suggestions. So we've collected some of our best ideas for this month's newsletter. We hope this makes your holiday shopping just a little easier.
If you're looking for a very special gift, a good place to start is with our Top Grade Gems. Our staff selects the finest pieces from our inventory for this group, so if you want our personal recommendations, you'll find them here. Not everything in this group is expensive, by the way; we include particularly fine examples of many inexpensive gems as well as our finest sapphire, tourmaline and spinel.
A personalized gift is always appreciated, so you may wish to consider a birthstone or anniversary stone. You can make your choice by month or by signs of the zodiac. There are recognized alternative choices for many months as well.
Another nice gift idea is a matched pair of gems. Well-matched pairs are actually quite difficult to find, but we buy our gems in volume and our staff spends a lot of time going through parcels of gems to put together matched pairs. We've made it a bit of a speciality and we typically have as many as 500 matched pairs in our inventory, with around 30 gem types represented. Click here to see all our matched pairs.
If you're looking for an inexpensive but unique gift, consider a gemstone carving. We have interesting figurines in a dozen different gem types, even some in sapphire and ruby. The carved turtles are a particular favorite and they are a traditional symbol of a long life here in Asia.
If you'd like to purchase a large gemstone but are looking for something fairly inexpensive, have a look at our huge selection of cabochons. These are popular with collectors and make nice momentoes as well as stunning jewelry. We currently have more than 25 types of cabochons in our stock.
Finally, we are often asked what are the best values in fine gemstones today. Everything seems to get more expensive every year, but in our opinion the finest gems for the price are tourmaline, spinel, spessartite garnet and zircon. This year we're recommending tanzanite as well, since we were lucky recently to buy some very fine pieces at an excellent price.
Shipping Advice for December
At this time of year we take special care to make sure our customers receive their orders promptly and reliably. We've shipped gemstones to more than 70 countries and we've become experts at international shipping. So here's some advice to take the worry out of ordering an important gift online.
We strongly recommend FedEx for all holiday gifts. It's fast (3 to 4 days to nearly anywhere in the world) and you can track your shipment online so you'll know exactly when it will be delivered. It is remarkably reliable as well. Just make sure your give us your correct address and provide a telephone number as well in case of any problems with delivery.
Please note that loose gemstones may be imported duty-free to the USA, but FedEx shipments to other countries may be subject to tax and duty. If you're unsure about the situation in your country, please email us and we'll advise you about the quickest and cheapest shipment method.
A final note: we cannot ship gemstones to France by FedEx due to customs clearance issues. Registered mail is the best shipping method to France, so order early! |
| New and Interesting Gems -- updated March 15th |
 |
Variscite from the United States: Variscite is a relatively rare phosphate mineral and high quality specimens are used as gemstones and for carvings. Its name derives from Variscia, the historical name of Vogtland in Germany, where it was first found in 1837. At one time it also went under the name Utahlite, since important deposits have also been found in Utah, USA. We've found some excellent cabochons in various shades of green, mainly in the 20 carat size. |
|
| |
 |
Goshenite from Russia: The colorless precious beryl is known as goshenite. It is named after the small town of Goshen in western Massachusetts where it was first described. Goshenite was once used for manufacturing eyeglasses and lenses owing to its excellent transparency. Goshenite belongs to the same family as emerald, aquamarine and morganite. We've found a small number of high quality pieces from Russia, in sizes ranging from 3 to 5 carats. |
|
| |
 |
Dumortierite Quartz from Namibia: Dumortierite Quartz is an ususual quartz that is integrown with the mineral dumortierite. The inclusions of dumortierite give it a deep blue color that is unique in the world of quartz. The color has similarities to lapis lazuli and sodalite, but with the superior hardness of quartz. We have a nice range of cabochons from 7 to 35 carats. |
|
| |
 |
Mali Garnet from Mali: Mali Garnet is a rare garnet that is a mixture of grossular and andradite garnets. The name derives from the West African country of Mali where this garnet was first discovered in 1994. Mali is still the only source for this unusual garnet. Though Mali Garnet is predominantly grossular by composition, the presence of andradite is responsible for its superb dispersion or fire, reminiscent of the most famous andradite garnet, demantoid. |
|
| |
 |
Rubellite Tourmaline from Mozambique: Rubellite, the intense ruby-red color of tourmaline, is one of the rarest tourmaline colors. We rarely find good specimens in the market, so we're glad to announce that we've just added more than a dozen new rubellite pieces to our inventory, mainly in the 1 to 3 carat size. |
|
| |
 |
Sillimanite Cat's Eye from Madagascar: Sillimanite is an aluminum silicate, related to both andalusite and kyanite. In fact these three minerals are polymorphs -- they share the same chemical composition but different crystal structures. Sillimanite is named after the American chemist Benjamin Silliman (1779-1864). Silliman was one of the first American professors of science at Yale University. We've bought some interesting sillimanite cabochons with an exceptionally vivid cat's eye. |
|
| |
 |
Sugilite from Australia: Sugilite is a rare mineral named after the Japanese geologist, Ken-ichi Sugi, who discovered it in 1944. It is rarely found as crystals, usually being massive in form. It has a distinctive purple colour and is usually opaque to translucent. Sugilite has sometimes been called purple turquoise although there is no real connection between turquoise and sugilite, except both are colorful cabochons that are very attractive when set in silver. We've just bought a new stock of some top-grade sugilite. |
|
| |
 |
Amazonite from Brazil: Amazonite is a gemstone variety of green microcline, a feldspar mineral. It is named after the Amazon river in Brazil, though surprisingly no deposits have been found in that location. The lively green or blue-green color is reminiscient of jade. We've just acquired a parcel of interesting cabochons in a vivid blue green, including some matching pairs. |
|
| |
 |
Color-Change Garnet from Tanzania and Madagascar: The rare color-change garnet from east Africa and Madagascar has been very popular, and we have been buying all the high quality pieces we can find. We have just added several dozen new pieces from Madagascar. These have a striking color change from golden to orange or pink. |
|
| |
 |
Charoite from Russia: Charoite is a new gem on the market, first appearing in 1978. It is found only in one location in Siberia, Russia. The color and patterns are quite unique, with swirling shapes of lavender and violet. It is sometimes described as having the appearance of a purple marble. We've just purchased a new lot of charoite cabs in a deep violet, in sizes up to 9 carats. |
|
| |
 |
Emerald from Colombia: We have just received a new stock of Colombian emeralds with rich color and good transparency. These are mainly ovals, pears and emerald cuts in smaller sizes, ideal for earrings and ring settings. |
|
| |
 |
Cat's Eye Scapolite from Madagascar: Scapolite displaying a cat's eye effect are rare and highly regarded in the gem trade, since they tend to have exceptionally sharp eyes. Just keep in mind that these are slightly soft stones (5.5 to 6 on the Mohs hardness scale) and are not suitable for rings. But they make terrific earrings and pendants. |
|
| |
 |
Blue Sapphire Pairs from Madagascar: We have been buying some outstanding blue sapphires from Madagascar recently, and we've put together several dozen matching pairs. These are mainly rounds and ovals, with a few square-cut as well. A classic stone for earrings and perfect for ring and pendant designs. |
|
| |
 |
Unheated Yellow Sapphire from Tanzania: Completely untreated yellow sapphire is rare and difficult to find, not to mention expensive. We have been finding some very good unheated yellow sapphire from Tanzania, mostly in sub-carat sizes. But we did find 5 very good pieces between 1.1 and 1.5 carats. These are all ovals with VVS clarity, at an excellent price for unheated material. |
|
| |
 |
Large Tourmaline from Mozambique: We have one of the largest inventories of tourmaline you'll anywhere, and we have just added many large pieces to our collection. You'll find pink, red, orange and green, as well as an amazing variety of multicolor and bi-color pieces. We also have a good stock in watermelon crystal slices. |
|
| |
 |
Demantoid Garnet from Namibia: Demantoid is the rarest and most valuable of the garnets, and is one of the most difficult to find of all colored gems. It is one of the few colored gemstones with a luster and brilliance similar to diamond. We have built up a stock of more than 150 pieces of Namibian demantoid, including some very fine matched pairs. |
|
| |
 |
Spinel from Burma and Tanzania: We buy fine spinel whenever we can find it, and we've recently added some very fine pieces to our extensive stock. You'll find red, violet, orange, blue and gray in a variety of shapes and sizes. Notable among these acquisitions are some larger pieces in the 2 to 4 carat size, and a number of hard-to-find matching pairs. |
|
| |
 |
Apatite from Madagascar: Apaptite from Madagascar is famous for a vivid blue-green that is reminiscent of paraiba tourmaline. We have just acquired a range of excellent new pieces. Most are in the 1 to 2 carat size, but we've also found a few rare stones in the 4 to 5 carat size. We also have stock in the popular green apatite, known as the "asparagus stone." |
|
| |
 |
Sphene from Sri Lanka: We have added some excellent new pieces to our stock of this rare gemstone famous for its remarkable dispersion or fire. These are bright golden and green pieces in interesting shapes and cuts, including a number of rounds in smaller sizes. Sphene tends to have inclusions, but we've found a number of eye-clean pieces. |
|
| |
 |
Chrome Diopside from Russia: Chrome diopside is one of the few gemstones colored by chromium. Its rich green is unique in the gems world, rivalled only by the best tsavorite garnet and chrome tourmaline. We have recently purchased some very fine matched pairs for earrings, as well as a number of very affordable pieces in smaller pieces. |
|
| |
 |
Spessartite Garnet from Mozambique: We have added a large number of new pieces to our extensive inventory of this very popular gem. We now have over 500 pieces in stock, in mandarin and red-orange, in both cabochon and faceted. The range of sizes and quality grades is extensive. Our most recent additions are in the best mandarin orange color, mainly in smaller sizes. |

Gemstones Worth Knowing
Each month we focus on one of the lesser known gemstones. This month's featured stone is Apatite.
Apatite, a stone seldom found in jewelry stores and virtually unknown to the general public, is beloved by collectors for its many different colors and forms. Only with the recent availability of the neon blue-green variety from Madagascar, has its jewelry use increased. The color of the best specimens of this type rivals the famed Paraiba tourmalines, but apatite is not quite as hard, so its not recommended for daily wear rings.
We have apatite from Madagascar in a range of greens and blues, including a number of pieces in the popular neon blue-green. To see all our stock in this intriguing gemstone click here.
Customer Questions
Every month we answer questions of general interest from our customers. Please feel free to send your questions to help@gemselect.com, with "Newsletter question" in the Subject line. |
| Q: |
What is the most durable gemstones? SK, USA |
| A: |
Many people would answer "diamond", since it is the hardest of all the gemstone materials. But there is more to durability than just hardness. For example, diamond has perfect cleavage, meaning it can be split with a single blow. Corundum (ruby and sapphire), while not quite as hard as diamond, has no cleavage, a property they share with spinel. Some other gems which are quite hard, such as emerald, typically have internal fractures which are filled by oiling, and thus require special care. For more information on caring for your fine gems, please see our information pages on Caring for Gemstones and Cleaning Gemstones.

| Q: |
When you give gemological information for each gem, you include something called "color of streak". What does that mean? Why is it important? Thanks, for your answer, DN, New Zealand |
| A: |
The streak test is one of the many methods used to identify gemstones. Each gemstone has an inherent color, that is, it's true color not affected by any impurities. The color of a mineral when powdered is called the streak of the mineral. Crushing and powdering a mineral eliminates some of the effects of impurities and structural flaws, and is therefore more diagnostic for some minerals than their color. Streak can be determined for any mineral by crushing it with a hammer, but it is more commonly obtained by rubbing the mineral across the surface of a hard, unglazed porcelain material called a streak plate. The color of the powder left behind on the streak plate is the mineral's streak.
