{"product_id":"diamond-macle-twin-var-congo-boart","title":"DIAMOND Macle Twin Var. CONGO BOART","description":"A great example of a Diamond Macle Twin with a triangular aspect and opaque deep pistachio-green colour.  The Diamond measures to 8 mm and is from the Kasai-Oriental area of the Democratic Republic of the Congo.  This area was extensively mined for placer Diamonds before the discovery of several Kimberlite pipes. It is a lovely example of this habit of Diamond and comes in a small clear plastic box with integral magnifying lens in the lid.  Macle is a crystallographic term which describes a twin crystal of spinel law habit forming two interwoven lozenge (or diamond) shaped prisms.  The regional name for such twins is Congo Boart, Boart being the term for a granular, opaque diamond.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781471248719,"sku":"CC5417","price":888.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC5417_dccd7ca1-43cc-4707-90b9-10a2c7aad78c.jpg?v=1783990124","url":"https:\/\/crystalclassics.co.uk\/products\/diamond-macle-twin-var-congo-boart","provider":"Crystal Classics UK","version":"1.0","type":"link"}
