Ask Arthur: Do You Have A Question?

Do you have any questions on your diamond ring that you have been wearing for years? Or your heirloom jade bangle or whether your loose faceted ruby colored stone is natural or synthetic?  How do you take care of your diamond pendant and other jewellery? Or is it worthwhile to liquidate your estate gold jewellery now when the gold price is at its all-time high?

As a practising gemologist and a diamond dealer for more than 25 years, I have often been sought for advice on questions relating to diamonds, colored stones, jade, noble metals and jewellery.

So, I start this column on ‘Ask Arthur’ to provide assistance and answers to questions from my readers.

If you want to make enquiries on your diamond ring, jewellery or colored stones, just follow these simple steps:

The above service does not constitute a service and payment contract.  No fee is charged.  However, Terms & Conditions apply. These are stated as below.

The opinion given will appear as a post. Your name and email address will not appear on the post. Instead an alias may be used.

Thank you

Arthur Lau
