Hello and welcome to Rock Logic

Our jewelry business began in 1988 and by 2000 we added loose rare gemstones to our fare. 

Our jewelry ranges from beaded to set gems, from base metal and sterling silver to 14k gold.  While browsing please keep in mind it can be difficult to get all current inventory uploaded in a timely manner, especially with the ancient Roman glass jewelry.  So, please enquire if you don’t see what you are looking for, and custom orders are always welcome too!

Just as with the jewelry, it can be difficult to upload all of our current gem inventory.  Please ask if you don’t see what you are looking for, we may have it or if not can get it.  Some of the rare gems we currently carry and have carried in the past include:  actinolite, adamite, afghanite, allanite, amblygonite, anapaite, anatase, andalusite, andradite, anorthite, apophyllite, augulite, austenite, axinite, azurite, bahianite, barite, bastnäsite, benitoite, beryllonite, bikitaite, bixbite (red beryl), boracite, brazilianite, brucite, bytownite, calcite, cancrinite, carletonite, cassiterite, catapleeite, celestine, chambersite, charlesite, chlorastrolite, chrome clinochlore, chrome diopside, chrysoberyl, clinohumite, clinozoisite, creedite, crocoite, cuprite, cuprovesuvianite (cyprine), danburite, datolite, demantoid, diaspore, diopside, dioptase, dolomite, dumortierite, dunilite, ekanite, enstatite, eosphorite, epidote, euclase, eudialyte, fibrolite, forsterite, friedelite, gahnite, gahnospinel, genthelvite, grandidierite, grossularite, hackmanite, hambergite, hauyne (hauynite), hemimorphite, herderite, hessonite, hexagonite, hubnerite, idocrase, indicolite, jeremejevite, kämmererite, kornerupine, kovdorskite, kurnakovite, kyanite, lazulite, legrandite, magnesioaxinite, manganandalusite, mangantremolite, manganvesuvianite, mellite, microlite, milarite, moldavite, monazite, montebrasite, natrolite, neptunite, olmiite, opal, painite, pargasite, parisite, peridot, petalite, pezzottaite, phosphophyllite, poldervaartite, pollcuite, powellite, prismatine, pyroxmangite, remondite, rhodizite, richterite, rhodochrosite, rhodonite, ruby, sapphirine, scapolite, scheelite, serandite, serendibite, shomiokite, shortite, sillimanite, sinhalite, smithsonite, sodalite, sphalerite, sphene, spinel, spodumene, staurolite, sugilite, suolunite, sunstone, taaffeite, tanzanite, thomsonite, tourmaline, tremolite, triphylite, triplite, tsavorite, tugtupite, ussingite, vesuvianite, villiaumite, viridine, willemite, wulfenite, yugawaolite, zektzerite, zinkite, zoisite.
