I used some very nice vintage 14kt gold plated 80's chain and ran it straight thru the silicone stopper. The chain measures 20 inches long with a spring clasp. The bottle measures 1 and 3/4 inches tall. The center purple stone is vintage german glass accented with a tiny baguette and very so tiny Swarovski flatback purple crystal. The finding is a rescued and altered earring with a brilliant diamond cut to get that added sparkle.
