I was browsing around for a deal on red beryl and found this. The silver contrasts beautifully with the onyx and the diamond adds an extra sparkle.
"This elegant Art Deco filigree oval pendant necklace in sterling silver features black onyx as a background, with pretty flowers, hearts, and scroll filigree and light capturing millgrain work adorning the entire design. From the heart of the dramatic onyx shimmers a 0.01 carat round brilliant cut diamond in a secure four prong setting. High polish filigree engraved openwork encircles the sides of the pendant with a lovely filigree fleur-de-lis bail providing an elegant finishing touch. Measuring approximately 1 3/8 inch high including the bail, by 3/4 inch wide, this joyous pendant comes with a classic 18 inch long sterling silver link neckchain and would make the perfect surprise for someone special - or for you!
