Diamonds are 10 on the mohs scale, the hardest things in the world. If there was a sparkliness scale, they’d be top of that too. And that’s the magic, that they’re so eternal and so beautiful, and they will bring joy for a lifetime and beyond. Nothing beats a diamond for bang for buck, and enjoyment per wear. If you work it out, a diamond ring that costs £2500 bought at the age of 30 will give 50 years good service if you live to 80. Which works out as around £1 a week over a lifetime, and diamonds can be passed on. Yes!! A great diamond is an investment in your happiness and can be passed through the generations and here’s a trove of heartbreakingly beautiful ones that your descendants will squabble over!!
