Car makers seem to have finally accepted that selling cars is actually harder and less profitable than selling other branded products. It's not (entirely) their fault, it's just the way it is with all these regulations on emissions and safety and so and so forth. Bentley is particularly apt because the German-owned, UK-based brand makes a variety of different things including pens, perfume and, as it turns out, gemstones. This is the new Bentley Jewellery collection , comprising yellow, orange and pink Padparadscha sapphires and Mandarin garnets along with different shades of purples and blues, incluidng Bentley's signature Sequin Blue. They're pricey, perhaps rather unsuprisingly, coming in at €6,000 or more but while we're at it, we might as well talk about it. So what's your favourite stone?
