My personal style signifier is my yellow-gold Audemars Piguet Royal Oak watch. The design is classic simplicity and it works alongside all my jewellery. I’m bored with the oversized trend; this is a 35mm midsize from the 1980s and it’s perfect. £27,600; www.audemarspiguet.com.
The last things I bought and loved were three Brian Rochefort ceramic cup sculptures from the Retrospective gallery in Hudson. They are wonderfully gloopy and colourful and sit on the mantelpiece at our home in Old Chatham, upstate New York. The gallery is in the middle of Hudson’s antiques district and has an incredible assortment of emerging international artists. About$1,000 each; 711 Warren Street, Hudson, NY 12534 (+1518‑828 2288; www.retrospectivegallery.com).
And the thing I’m eyeing next is a Maltese Cross cuff by Verdura. I hardly ever covet jewellery by other designers, but his story comes from a truly glamorous time. He was the cousin of Giuseppe Tomasi di Lampedusa and got his break in jewellery when Cole Porter introduced him to Coco Chanel. He went on to produce some of the most iconic and daring pieces of the 20th century. From $35,500; Harry Fane, 13 Duke Street, London W1 (020-7930 8606; www.harryfane.com).
The site that inspires me is the Montenegrin coastline by the Bay of Kotor – Byron was right when he said it was the most beautiful encounter between land and sea. We opened a store in Porto Montenegro before there was really anything there, a decision based solely on a connection to its natural beauty.
A recent “find” is an amazing catering firm called Munch Food Company. The chef and owner Keith Goddard organised a last-minute birthday party for me with all my favourite Italian food – including lemon linguine, which is difficult to get just right – and the best ingredients like fantastic burrata, heirloom tomatoes and puntarelle. It was perfect. 020-7627 8930; www.munchfoodcompany.com.
The best gift I’ve given recently is a 1980s black convertible Mercedes 300SL, to my husband for his 40th birthday.
And the best one I’ve received is an antique American flag with the number 76 on it – 1976 was both the bicentennial of the US and the year I was born. I’d never put the two together but it led to our latest collection, Superstellar, which also celebrates another anniversary – my family’s 130th in the jewellery business.
The last music I downloaded was the folk/indie album Angus & Julia Stone by the band of the same name. They are an Aussie brother and sister and their voices and melodies are very gentle, the lyrics just the right side of offbeat – perfect to design to.
An indulgence I would never forgo is masses of fresh flowers everywhere, at work and at home. They make rooms complete and I would cut a lot of other expenses before I stopped buying them. I particularly like the free, tumbling style of JamJar Flowers. 7/7A Peacock Yard, Iliffe Street, London SE17 (020-7738 7054; www.jamjarflowers.co.uk).
The beauty staples I’m never without are Calyx, the only scent I have ever worn, originally made by Prescriptives and now owned by Clinique, and Classic ChapSticks. I love the tingling feeling when you put them on and have them in every pocket and bag. Calyx, from £46 for 50ml; www.clinique.com. Classic ChapStick, £3.99; www.chapstick.com.
The last item of clothing I added to my wardrobe was a Vita Kin floral romper from Alex Eagle on Walton Street, which has an amazing selection of small under-the-radar labels. I like floaty, colourful clothes but this is not just another boho brand – it features traditional embroidery from Ukraine, not an easy place to have a fledgling fashion business right now. 91 Walton Street, London SW3 (020-7589 0588; www.alexeagle.co.uk).
My favourite websites are interior designer Mark D Sikes’s blog and It’s Nice That, which showcases the freshest graphic design, art, video and sculpture. I also love the Dubsmash app, where you lip‑sync to famous lines from films. My friend and I have a running competition to see who can out-silly the other. www.dubsmash.com. www.itsnicethat.com. www.markdsikes.com.
