Should I rely on a certificate for quality and value?
A certificate is actually a record or proof that a particular piece of gemstone has been examined by an independent gemological laboratory. The measurements and grading reflected on the report tell the quality and value of a particular piece of gemstone.
Do I need an appraisal for my diamonds?
This depends on the value of that particular piece of jewellery. An appraisal is required for insurance purposes. In the cases of theft and robbery, an insured piece of jewellery will be compensated by your insurance company based on the price as reflected on the appraisal. This is a common practice in the United States and Europe but is seldom practised here.
How can I get an appraisal for my diamonds?
A Graduate Gemologist and/or a Certified Appraiser working in an independent laboratory is qualified to appraise jewellery and gemstones. Ask to see proof of their professionalism before you send your jewellery or gemstones for an appraisal.
How should I take care of my jewellery?
Taking good care of your jewellery ensures that you get many years of pleasure from it. Over time, accumulated dirt and grease may affect the brilliance of your gemstones. To maintain the sparkle of your gemstone jewellery, clean it once a month with a mild soap and a soft toothbrush. We also recommend that you send your jewellery to an established jeweller at least twice a year to have it professionally cleaned and examined.
Where and how should I keep my jewellery?
We recommend that you keep your jewellery in a hard jewellery case with different compartments for rings, pendants and earrings etc. All jewellery are delicate items no matter what settings they are in, so they should not be stored together. Doing so might cause abrasion which will eventually lead to chips and fractures on both gemstones and metals.
