  • simulated ruby

    Our lab-made simulated rubies have all the radiant sparkle of natural mined rubies, only at a more affordable price. Since they're sustainably created in a lab, simulated rubies also do not cause any additional strain on the ecosystem compared to mined rubies

  • 14k Gold over Silver

    A thick layer of 14k gold bonded over sterling silver is what gives this piece it's beautiful hue and durability. Since gold is one of the least reactive metals, it scratches less and doesn't wear out as easily. 14k gold will not oxidize or discolor, so you can wear your jewelry every day, everywhere.

Love it!

My first "Rubi" piece and I love everything about this. Gorgeous color, look, and very comfortable. Would definitely order again

Necklace is gorgeous!

The necklace is stunning, and the gems are even more sparkling and beautiful in person than they appear in the photos. Makes a great "go-to" piece for a night out for me. Very pleased!

I would have loved to keep this but the clasp is just so bad. It's really a pain to fasten it or undo the clasp when I need to take it off, so I plan to return it

The gemstones are very pretty and shiny, but I thought they would have been a bit larger from the photos
