Ruby is the name of the deep red gemstone, from the Old French rubi and the Latin rubeus, “red”.
Victorian families added it to the jewel names for girls, beside Pearl and Beryl. The red stone has long stood for passion and courage, which gives the name a warm connotation.
The name Ruby in numerology
R 9, U 3, B 2 and Y 7 come to 21, and 2 with 1 gives 3.
A Ruby usually has something to say and a way of saying it that makes the room lean in. She sings, draws, dresses with flair or writes funny notes; her creative streak turns a plain afternoon into a small event.
The vowels U and Y make 10, or 1 once folded: privately she hopes to run her own show and to be first at things. R and B, the consonants, reach 11, left whole, which gives her way of working an intuitive, sensitive tinge. She notices what others miss and trusts her ear.
R is worth 9 here, so strangers meet someone warm and open-handed; U is worth 3, so in a sudden turn she turns the moment into a story.
Expression, independence and intuition fit into four letters, like a small gem with several facets. It outlines the name rather than the person, who is shaped by many other figures.
