Mineral of the Week
#75632, Fluorite (with phantom-growth zoning) with Calcite, Xianghuapu Mine, Xianghualing, China (t) $325
News and CommentsEver since I was a beginning mineral collector back in 1968 I always owned only a shortwave (254 nm) ultraviolet light. The conventional wisdom was that most of the good fluorescent minerals would fluoresces best under shortwave ultraviolet light. Every mineral (70,000+) posted to this site over the years was checked for fluorescence under shortwave ultraviolet. The gallery of Fluorescent_Minerals were all illustrating only shortwave fluorescence. Last week I acquired a new longwave (365 nm) ultraviolet light. I was surprised to see how many minerals on this site fluoresce under longwave, but failed to fluoresce under my old shortwave. This week I posted a group of diamond crystals that all fluoresce under longwave ultraviolet, and many phosphoresce too. In the future, I will check all other minerals for longwave fluorescence and will update them like I did the diamonds this week. If you want to acquire a reasonably priced longwave light, I recommend the flashlight-type that look like a high-powered LED flashlight, but has a 365 nm longwave light in it. I purchased mine from Patrick Bigos of Midnight Minerals (https://www.midnightminerals.com) in southern Maine. The longwave light was $60 with rechargeable battery and charger. A bargain! John H.

Customer Comments:"Some months ago, we asked if you could obtain for us a specimen of Fluorite from Illinois. We left you to it knowing that sooner or later you would come up with the goods. And you certainly have. It is an absolute magnificent Fluorite and we can't thank you enough for going to all that trouble to obtain it for us." Marie... "Thank you John! I just added two nice Diamonds from the North Cape Province, South Africa to my collection. John's service is impeccable! My new prized specimens were described honestly and photographed perfectly. I am a very happy collector! For everyone seeking to buy collection grade (or jewelry grade) Diamonds, John Betts fine minerals in New York is the place to go!" Michael P. "I'm very happy with the beautiful calcite on dolomite mineral I purchased from you. The fluorescence is awesome! As always,it was superbly packed and delivered, and the price very fair. I look forward to my next transaction with you. "G. Tucker "I just received my order of beautiful Copper from the Ray Mine in Arizona and Native Silver with Acanthite from Batopilas, Chihuahua Mexico. Both arrived in perfect condition and I am thrilled & honored to add these awesome minerals to my Native Elements section of my collection. These beauties will add much "spice" to that group. These and all your minerals are "show worthy" pieces at bargain prices. Thank you a million times! 5 stars +++++ for this dealer!" M.P. "Thanks, John. The sapphire just arrived in fine shape. Very nice and the color and clarity were well-represented by your photographs. Another satisfied customer!" D.D.
