‘You don’t actually have to hang on to it,’ the Prince said. ‘My father would not be in the least offended if you were to sell it. Who knows, one day you might need a little pocket-money.’
‘I don’t think I shall sell it,’ Robert Sandy said. ‘It is too lovely. Perhaps I shall have it made into a pendant for my wife.’
‘What a nice idea,’ the Prince said, getting up from his chair. ‘And please remember what I told you before. You and your wife are invited to my country at any time. My father would be happy to welcome you both.’
‘That’s very good of him,’ Robert Sandy said. ‘I won’t forget.’
When the Prince had gone, Robert Sandy picked up the diamond again and examined it with total fascination. It was dazzling in its beauty, and as he moved it gently from side to side in his palm, one facet after the other caught the light from the window and flashed brilliantly with blue and pink and gold. He glanced at his watch. It was ten minutes past three. An idea had come to him. He picked up the telephone and asked his secretary if there was anything else urgent for him to do that afternoon. If there wasn’t, he told her, then he thought he might leave early.
‘There’s nothing that can’t wait until Monday,’ the secretary said, sensing that for once this most hard-working of men had some special reason for wanting to go.
‘I’ve got a few things of my own I’d very much like to do.’
‘Off you go, Mr Sandy,’ she said. ‘Try to get some rest over the weekend. I’ll see you on Monday.’
In the hospital car park, Robert Sandy unchained his bicycle, mounted and rode out on to the Woodstock Road. He still bicycled to work every day unless the weather was foul. It kept him in shape and it also meant his wife could have the car. There was nothing odd about that. Half the population of Oxford rode on bicycles. He turned into the Woodstock Road and headed for The High. The only good jeweller in town had his shop in The High, halfway up on the right, and he was called H. F. Gold. It said so above the window, and most people knew that H stood for Harry. Harry Gold had been there a long time, but Robert had only been inside once, years ago, to buy a small bracelet for his daughter as a confirmation present.
He parked his bike against the kerb outside the shop and went in. A woman behind the counter asked if she could help him.
‘Is Mr Gold in?’ Robert Sandy said.
‘Yes, he is.’
‘I would like to see him privately for a few minutes, if I may. My name is Sandy.’
‘Just a minute, please.’ The woman disappeared through a door at the back, but in thirty seconds she returned and said, ‘Will you come this way, please.’
Robert Sandy walked into a large untidy office in which a small, oldish man was seated behind a partners’ desk. He wore a grey goatee beard and steel spectacles, and he stood up as Robert approached him.
‘Mr Gold, my name is Robert Sandy. I am a surgeon at The Radcliffe. I wonder if you can help me.’
‘I’ll do my best, Mr Sandy. Please sit down.’
‘Well, it’s an odd story,’ Robert Sandy said. ‘I recently operated on one of the Saudi princes. He’s in his third year at Magdalen and he’d been involved in a nasty car accident. And now he has given me, or rather his father has given me, a fairly wonderful-looking diamond.’
‘Good gracious me,’ Mr Gold said. ‘How very exciting.’
‘I didn’t want to accept it, but I’m afraid it was more or less forced on me.’
‘And you would like me to look at it?’
‘Yes, I would. You see, I haven’t the faintest idea whether it’s worth five hundred pounds or five thousand, and it’s only sensible that I should know roughly what the value is.’
‘Of course you should,’ Harry Gold said. ‘I’ll be glad to help you. Doctors at the Radcliffe have helped me a great deal over the years.’
Robert Sandy took the black pouch out of his pocket and placed it on the desk. Harry Gold opened the pouch and tipped the diamond into his hand. As the stone fell into his palm, there was a moment when the old man appeared to freeze. His whole body became motionless as he sat there staring at the brilliant shining thing that lay before him. Slowly, he stood up. He walked over to the window and held the stone so that daylight fell upon it. He turned it over with one finger. He didn’t say a word. His expression never changed. Still holding the diamond, he returned to his desk and from a drawer he took out a single sheet of clean white paper. He made a loose fold in the paper and placed the diamond in the fold. Then he returned to the window and stood there for a full minute studying the diamond that lay in the fold of paper.
‘I am looking at the colour,’ he said at last. ‘That’s the first thing to do. One always does that against a fold of white paper and preferably in a north light.’
‘Is that a north light?’
‘Yes, it is. This stone is a wonderful colour, Mr Sandy. As fine a D colour as I’ve ever seen. In the trade, the very best quality white is called a D colour. In some places it’s called a River. That’s mostly in Scandinavia. A layman would call it a Blue White.’
‘It doesn’t look very blue to me,’ Robert Sandy said.
‘The purest whites always contain a trace of blue,’ Harry Gold said. ‘That’s why in the
