Certification - Ouellet & Lynch full laboratory appraisal. They appraise colored gems for the Smithsonian's Traveling and home exhibits and they appraised all of the gems recovered from the Titanic. This has an actual value appraisal not a guesstimate, or simply a jeweler looking through a loupe. They have a state of the art lab. This gem was also checked by the University of Moscow Gemological Department which knows as much about Demantoid as DeBeers knows about diamond and have the finest state of the art equipment in their well respected laboratory.
Notes - This gem contains a slight blue hue. Blue coloration is very rare and often more blue will raise the price of the gem dramatically. Though slight this is a huge plus when buying a Russian Demantoid. Blue was identified by Craig Lynch who is one of the most respected appraisers internationally and his appraised pieces have often exceed his appraised value at auction which is commonplace with Demantoid, (as per,) Ales Krivinek of Ravenstein Investment Gems, an expert on Russian Demantoid and other rare Russian Gems.
NOTES - You may request to preview the appraisal upon request the appraisers credentials below. This gem was also fully and officially certified by the Gemological Department of The University of Moscow,considered to be the top authorities on this rare gem. Russian Demantoid in both color and quality are much more desirable than Demantoid garnets found in Namibia Or other areas that they command a much higher price and are considered to be by far the rarest and most desirable garnet on the planet. Horsetail inclusions are the birthmark of true Russian Demantoid. They add to the value of the gem but are not expected to be eye visible in top gems. Just a small inclusion adds value because it makes the gem easily identifiable as Russian Demantoid.
This incredible VS quality Demantoid has a Horse Hair Inclusion visible at 10x Magnification. It is a Top Fire gem with incredible clarity for a gem of this rare size and it has higher dispersion than diamond.
The highest dispersion is in bright green gems are of type #4 color which should be an eye clean, bright green exhibiting a slight yellow hue (less than 10% yellow undertone.) These gems have gorgeous sparkle and multicolor flashes (surpassing diamond in dispersion) even in larger gems over 3 carats.
Type 3# is Chrome Green And at its finest will be eye clean and have a slight blue hue. They show best color in small gems or those up to about 3 carats and they may appear too saturated and dark or flat when very large. Large gems over 3 carat will lose a lot of dispersion.
The next is type #2 which is an emerald green and also shows better dispersion in smaller gems and can appear flat in larger sizes though the rarity still makes large gems very valuable.
Type #1 is bluish green and are so rare they are almost never found and they can easily surpass one million dollars for a single gem. These gems almost never leave Russia and when on the open market are often type #2 or #3 gems simply misidentified.
NOTE LARGE DEMANTOID - Demantoid are very rare in gems 1 carat and larger the vast majority are under 1 carat. Any gem over 2 carats is very rare and over 3 carats exceptionally rare. 4.5 carat gems of this color, high dispersion, quality and clarity are rarely available on the world market. Especially with such an exceptional pedigree.
Any gem below type #4 is either too yellow or even brown and undesirable thought any Demantoid from Russia may be expensive even in primarily yellow gems.
Type #4 is highly desirable for gems over 3 carats because type #1-#3 get very saturated and can appear dark and have much less light dispersion than diamond in larger gems and can appear flat due to over saturation of color. Type #4 maintains its diamond like dispersion even in larger gems.
The availability of these gems could end at any time due to numerous factors so we suggest you stock your stores now, or for those investing in larger gems to invest in Demantoid has never gone down in price since introduced to America in the 1800’s by Tiffany & Co.’s Louis Comfort Tiffany who fell in love with the gem when auctioning the Czars Royal Gems when the Russian Royal Family were all murdered. He began exporting the gems and using them in some of Tiffany’s most notable pieces which now sell for tremendously high prices.
The cost could explode if availability ceased since mining has often been halted for decades at a time. The mines lay dormant for about half a century in the 1900’s. If declared a type 1 gem the gems could be nationalized and become very controlled and the mine operations taken over by the government subjecting them to embargoed or other tariffs. They are even now very difficult and expensive to report and are taxed and expensive to transport safely.
They still use the same old mining equipment used decades ago for extracting these gems slowly. Almost all of the work is still done by hand, aided by old and outdated equipment. Their cutters are trained from an early age and gems are usually round brilliant of fine quality and on occasion cushion cut. This gem was viewed/tested for about 1 hour and 45 minutes in the lab. by Craig Lynch. All certifications will be included with purchase.
(Note Oullet & Lynch are hired by the Smithsonian for appraising colored gems to be exhibited and/or used in special displays shared with other museums and they appraised all of the gems recovered from the Titanic after the vessel sank.
