Invitation to the Cocktail Reception

Being involved with Tiancheng International Auctions since 2013, we usually get our catalogs issued gratis.

For this event, we received our parcel via mail around a month before the event. It comes with a postcard invitation to the cocktail reception, the summarized price list and the highly anticipated full auction catalog.

Auction Catalog

The auction catalog only shows the best side of the jewellery we are interested in buying. By analysing Tiancheng's valuation, it give us a good indication on the extent the gemtone may differ when seen in person. This is often due to colour saturation or the cutting of the gemstone in pictures. At certain angles, a gem can appear to have less extinction.

Preview & Cocktail Reception

The jewellery auction preview is held for 3 days before the actual auction. Most of the time, serious buyers would make the trip to personally inspect the pieces. Aspects such as luster, cutting and inclusion are not visible in the catalog pictures, so this is an important check process especially for big ticket items.

The best jadeite luster is described as having water dripping out it the stone.

Ruby and Diamond Ring. This impressive piece was sold for HK$23,040,000. Featuring a 20.09carats Mozambique Pigeon's Blood Unheated Ruby, this piece was formally auctioned at 2013 Autumn Auctions and sold for HK$15,930,000.

Within 6 years, the prices have increased by HK$7 million. This is the reason why experienced buyers only buy investment grade jewellery. And very often, auctions are the only way to acquire them.


Upcoming at Sotheby's!

We are extremely excited to announce that we will be a part of Sotheby's Hong Kong Autumn Auctions; Magnificent Jewels and Jadeite.

We have consigned a 8.24 carat Round Brilliant Diamond adorned with 13 Tsavorites and 15 smaller diamonds. While the auction will be held on 7th October in Hong Kong, the Singapore travelling exhibition will be on 14th - 15th September at The Regent Hotel.


1) Don't forget about the buyer's premium!

They may go up to 20% depending on which auction houses.

2) Always check the gemstone in person during travelling or pre-exhibitions.

Never buy solely based on an image. Pictures only show the best side of the gemstone.

3) Always examine coloured gems in a variety of lighting (Daylight and Yellow Light).

4) Always cross refer prices with similar past auction results.

Check with various auction houses, i.e. Sotheby's, Christies
