Hi! Since you're open to other brands, here are a few ideas:
Van Cleef & Arpels
- Sweet Alhambra MOP pendant – I find the mother-of-pearl really flattering; it lightens up the face and stands out beautifully on any skin tone
- Sweet Alhambra bracelet (heart or classic clover)
- Sweet Alhambra butterfly pendant
- Sweet Alhambra heart pendant
Cartier
- Trinity ring
- Trinity cord bracelet
- Diamants Légers bracelet (XS or S)
- Diamants Légers necklace (XS or S)
- Amulette de Cartier (I'm seeing a bracelet available in EU, not sure about US)
Tiffany & Co.
- Elsa Peretti Diamonds by the Yard necklace
- Tiffany T Smile mini pendant
Chaumet
- Jeux de Liens Harmony mini pendant
Boucheron
- Serpent Bohème XS pendant - I tried this one in diamond pave, which is slightly over your budget, and loved it! It's super sparkly, elegant and unusual, I haven't seen it on anyone in real life. The options with gemstones are within your budget and stunning too!
