The red grape variety is an interspecific new variety between Diana (1) x Chambourcin. Synonyms and breeding numbers are Geilweilerhof 67-198-3 and GF 67-198-3, which contain genes from Vitis labrusca, Vitis lincecumii, Vitis rupestris and Vitis vinifera. The hybrid was crossed in 1967 by Dr Gerhardt Alleweldt (1927-2005) at the Geilweilerhof Institute in Siebeldingen/Pfalz (Germany). The name is derived from the famous diamond (140.5 carats) which was on the crown of Louis XV (1710-1774) at his coronation in 1722 and which was later frequently worn by Marie-Antoinette (1755-1793). It also adorned the sword pommel of Emperor Napoleon Bonaparte (1769-1821), and today the diamond can be found in the Louvre in Paris. The variety was a crossing partner of the three new varieties Calandro, Julius and Reberger.

Serious sources on the internet are rare - and Wine lexicon from wein.plus is one such source. When researching for my articles, I regularly consult the wein.plus encyclopaedia. There I get reliable and detailed information.
