Carrie and fiancé Boris Johnson have just welcomed their first child

Carrie Symonds took to Instagram for a double pronged announcement when she and Prime Minister Boris Johnson got engaged and fell pregnant and, today, the couple welcomed their first child: a "healthy baby boy". In honour of their exciting news, take a look at Carrie's gorgeous engagement ring, as well as the surprising facts you definitely won't have expected.

Carrie Symonds' engagement ring inspiration

Featuring an oval-cut coloured stone and a frame of diamonds on a pave band, Carrie's ring bears a striking resemblance to the Duchess of Cambridge's. In fact, the only difference we can see is that the central stone on Kate's engagement ring is blue, not green.

Carrie Symonds' engagement ring cost

We knew Carrie's ring would be expensive, but apparently the design is worth approximately £30,000. Experts told the that the central emerald stone looks as though it has had no treatment at all (making it more valuable), and that it is probably a three-carat stone surrounded by two carats of diamonds.

Boris opted for an emerald stone on Carrie's engagement ring. According to experts, emeralds are said to be a bad choice of stone for an engagement ring since they are too soft for everyday wear and can be susceptible to chips and scratches. On the other hand, diamonds are incredibly hard which is why it makes for a wise engagement stone choice.

Carrie Symonds' engagement ring heritage

Carrie's ring is said to be a Johnson family heirloom. Though this is in keeping with Carrie's sustainable agenda, it is nothing like the modern style that Johnson proposed to his ex-wife Marina Wheeler with.

Prime Minister Boris opted for a bold emerald green stone, as opposed to a traditional diamond for Carrie's engagement ring. This is an unconventional move for Boris, but apparently the trend for coloured stones dates back to Princess Diana's sapphire and diamond ring (which Prince William went on to propose to Kate Middleton with).
