I often receive "Your pictures/descriptions/values, etc. are too good to be true" messages.
As for pictures - they are mostly for reference purposes only. Some (mostly of our photographer) are very good but rather surrealistic/artistic - not realistic. However, I strongly believe that if stone is described as "high-end" or "absolutely high-end" it is better than the picture of it no matter how good it is.
Descriptions are always accurate.
Prices/values are too good to be true indeed but they are "hard to believe but true." 99% of stones I list are top to absolutely high-end. "Just good" my partner sells to jewelers off eBay and Gemrock and sometimes I combine them in lots and list for super bargain prices. I list top stones for ridiculous prices for advertisement, not for profit - to attract real world clients that are willing to pay real world prices. Buy with confidence.
Note: We combine shipping. Each additional stone is $0.50 ($1 for a piece of jewelry). Since Gemrock doesn’t provide this option and charges the full shipping price for each item, please ask us for a total invoice.
All tanzanites I list came from the one very big parcel. With a few exception all have perfect IF clarity. All have gorgeous color. All have very high quality. Difference is little: a bit darker, a bit lighter; a bit more violet, a bit less.
Usually I write long descriptions. In case of these tanzanite descriptions don't make any sense. One description is good for all stones. Details will be my personal opinion. You may have different one.
Pictures. Usually buyers try to figure out how clean a stone and how good its color. When all stones are perfectly clean the only thing that left is color. The usual problem with color on pictures is camera's filters. They always alter color. But for tanzanites there is an additional thing. Naturally trichroic, tanzanite shows different colors when viewed through each of its three crystal axes: blue, red-violet and yellow-green. Because of it the same stone may show different colors on pictures. Camera sees it only from one static position. But it is only the beginning. Stones from this parcel have exceptional brilliance and glow. Now we are speaking about dispersion (separation of compound light).
Conclusion. Buying precious stones online is extremely difficult. Many buyers rely on pictures, it is a HUGE mistake. More experienced buyers rely on specifications and descriptions (if a seller bothers to write them). In case of these tanzanites there is nothing to rely on at all. Sorry, but you have to see a stone in person b. I can guarantee that you'll get a great stone but I cannot guarantee it will be exactly what you want. One may say: "I wanted more blue stone," - another "More deep violet." Same about the Tone: "I wanted darker one," "It is too dark." Sorry, I don't know your preferences.
I often give an information about FAIR and REASONABLE - not astronomical in various industry price lists - prices and post price list of Gem World International - Bible of every jeweler, gem dealer and serious buyer. But we live in ever-changing world. A few days ago (in October 2019) one customer sent me a message:
"Came back from the HK (Hong Kong - one of the few top dealers only gem shows) gem show last month and the prices were crazy high. No Zambians for less than $800/ct, and couldn't even get a whiff of even low grade Colombians for less than $4,000/ct.
Just ok colour heat only sapphires started at $1,000/ct. Unheated somewhere over $3,000/ct.
Needless to say I came away very unimpressed! These people were supposed to be wholesalers, trying to price like a retail store."
I didn't go to gem shows for about a year and contacted our supplier that attended almost all of them. Yes, it is prices now and he added that prices for such stones as tanzanite and paraiba tourmaline (I don't sell tourmaline) are moving steadily towards astronomical. Still, in the light of upcoming Holiday Season I am not going to increase prices for already listed stones and will continue to sell for "obsolete" prices to the end of the year.
