Cool diamonds were excellent - remember virtually all decent reputable Hatton Garden places you will need to make an appointment and most not open on Saturdays.
This was an excellent article - certainly helped me!!
Plus under no circumstances buy on the high street!! We looked at Mappin and Webb etc to get an idea of styles then prompltly went off to Hatton Garden and paid 1/3 of the price.
High st jewellers will generally try to get you to buy there existing stock, most hatton garden places will make it up and will take 2 to 4 weeks for it to be ready.
Jude may want the largest diamond - but colour is the most important - D, E or at worst F colour - any other and you can see it. Between 0.5 and 0.75 with the best colour and you won't go far wrong.
