The beauty of much quartz derives from other minerals trapped or grown within it. The coloured spangles seen in aventurine quartz are caused by small reflecting flakes of green fuschite mica, brown iron oxides or silvery coloured pyrite crystals. When quartz forms as a mass of microscopically small crystals it is known as ‘microcrystalline quartz’ or ‘cryptocrystalline quartz’. This family includes all varieties of chalcedony such as agate, carnelian and sard. Opaque, granular microcrystalline quartz is known as jasper. Chalcedonies and jaspers occur in a huge variety of colours, created by small amounts of impurities such as iron, manganese and chrome.\r\nThis ring forms part of a collection of 154 gems bequeathed to the V&A by the Reverend Chauncy Hare Townshend, a cleric and poet. Sir A. H. Church gave additional specimens in 1913. He also compiled the first catalogue <i>Precious Stones: A Guide to the Townshend Collection</i>. The first edition appeared in 1883. The stones are mounted as rings, although they may not have been intended to be worn.","physicalDescription":"Ring of spangled green oval aventurine quartz set a in plain gold mount.","artistMakerPerson":[{"name":{"text":"Unknown","id":"A1848"},"association":{"text":"","id":""},"note":""}],"artistMakerOrganisations":[],"artistMakerPeople":[],"materials":[{"text":"aventurine quartz","id":"AAT11154"},{"text":"gold","id":"AAT11021"}],"techniques":[],"materialsAndTechniques":"Aventurine quartz, set in gold","categories":[{"text":"Jewellery","id":"THES48930"},{"text":"Metalwork","id":"THES48920"},{"text":"Europeana Fashion Project","id":"THES265804"}],"styles":[],"collectionCode":{"text":"MET","id":"THES48599"},"images":["2007BR2194","2007BR2195","2007BP6049","2007BP6048","2006AN7429"],"imageResolution":"high","galleryLocations":[{"current":{"text":"91","id":"THES49703"},"free":"","case":"50","shelf":"M","box":"127"}],"partTypes":[[{"text":"Ring","id":""}]],"contentWarnings":[{"apprise":"","note":""}],"placesOfOrigin":[{"place":{"text":"Europe","id":"x28842"},"association":{"text":"made","id":"x28654"},"note":""}],"productionDates":[{"date":{"text":"1800-1869","earliest":"1800-01-01","latest":"1869-12-31"},"association":{"text":"made","id":"x28654"},"note":""}],"associatedObjects":[],"creditLine":"Bequeathed by the Rev.

Although the collection is not as comprehensive as that found at the Natural History Museum, it is of particular historic interest as its formation pre-dates the development of many synthetic gemstones and artificial enhancements. All the stones were mounted as rings before they came to the Museum, mainly in a series of standardised gold settings, often of the coronet or galleried type. However, several specimens are set with greater elaboration, with diamond borders surrounding the central stone. Some of these were originally in the possession of Henry Philip Hope (d.1839), a brother of the novelist and antiquary Thomas Hope (c. 1770-1831). H.P. Hope formed a famous collection of diamonds and precious stones which was largely inherited by his three nephews. His collection, which included the Hope blue diamond, now in the Smithsonian Institution, Washington, was catalogued by B. Hertz in 1839. \r\nTownshend is recorded as having made purchases from it and his acquisitions are noted below. He also seems to have remounted several of his purchases, in whole or in part.","historicalContext":"","briefDescription":"Aventurine quartz set in a plain gold ring, made in Europe, 1800-1869","bibliographicReferences":[{"reference":{"text":"","id":""},"details":"","free":"Sir A H Church, <font -u>Precious Stones: A Guide to the Townshend Collection</font>, 1883, Chapman and Hall Ltd"},{"reference":{"text":"","id":""},"details":"","free":"Clare Phillips, <font -u>Jewels and Jewellery</font>, V&A Publications 2000."}],"production":"","productionType":{"text":"","id":""},"contentDescription":"","contentPlaces":[],"associatedPlaces":[],"contentPerson":[],"associatedPerson":[],"contentOrganisations":[],"associatedOrganisations":[],"contentPeople":[],"associatedPeople":[],"contentEvents":[],"associatedEvents":[],"contentOthers":[],"contentConcepts":[],"contentLiteraryRefs":[],"galleryLabels":[],"partNumbers":["1205-1869"],"accessionNumberNum":"1205","accessionNumberPrefix":"","accessionYear":1869,"otherNumbers":[],"copyNumber":"","aspects":["WHOLE"],"assets":["2019LN4162","2019LT3905","2019LW9186"],"recordModificationDate":"2025-04-12","recordCreationDate":"2003-02-17","availableToBook":false}}
