Big celebrities and even bigger diamonds. That’s how Tiffany & Co. made a splash in Australia when it opened its new Sydney flagship this week.

All eyes were on brand ambassador Kendall Jenner, who donned a delightful bubble gum pink and feathered mini dress by Ingie Paris along with serious statement jewelry: a stunning pink tourmaline and sapphire butterfly necklace from the Tiffany Blue Book Collection, which features over 400 pink sapphires and a cushion-cut morganite of approximately 11 carats. That’s not all. She also sported a selection of diamond rings from the Tiffany T collection. Swoon!

Other notable attendees included Lara Worthington, Jesinta Franklin, Victoria Lee, Renell Medrano, and A$AP Ferg – the latter completing the night with a special performance in a diamond necklace from the Tiffany HardWear Pearl Collection, which launches in September.
