I used to have a good job in a top london law firm. Now I am a stay at home mum of 3. I regret not making these sorts of purchases back then when I had extra money and no dependants. There is no way I could justify spending that sort of money on a piece of jewellery for myself now, but in hindsight I wish I had back then. Instead I had holidays and nice furniture and clothes and a house ... But life and fasions move on and it has all gone now. I wish I had invested in a timeless piece of jewellery back then, to last a lifetime. So my advice would be to definitely go for it. Its hardly like you are leaping on a fad since you have coveted it for so long. Get it now and you will have more years to enjoy it.
