One of the world’s great natural treasures, the Pink Star diamond will lead Sotheby’s sale of Magnificent Jewels and Jadite in Hong Kong 4 April. Estimated in excess of US$60 million, this 59.60-carat oval mixed-cut pink diamond is the largest Internally Flawless, Fancy Vivid Pink diamond ever graded by the GIA. The sale of the Pink Star continues Sotheby’s tradition of bringing some of the rarest and most extraordinary collectibles to market.


Experts are calling for a below-normal hurricane season this year, as a potential El Niño may limit the development of storms.

AccuWeather meteorologists are predicting 10 named storms, five of which are projected to become hurricanes and three of which may become major hurricanes. 

“The big factor is going to be the fact that we now believe El Niño will come on board some time during the summer and will continue all the way through the rest of the hurricane season,” AccuWeather Meteorologist Dan Kottlowski said.

Here is the link for more about that.


When people talk about beach conditions, the two factors they typically talk about is high seas and the wind.  Other than those two important factors there are others that are important.  Here is a list of ten factors that determine how a beach will erode.

1.  Size of the waves.

2.  Direction of wind and waves.  This is actually relative to the beach and long shore currents.  On the Treasure Coast waves hitting from the north are best.

3. Tides.

4. Amount of sand or depth of water in front of the beach.

5. Where the waves are breaking.  This factor is determined largely by numbers 1, 3 and 4.

5. Timing.  High waves are more effective when the tide is also high, for example.

 6.  Obstacles such as inlets, rocks or sea walls.

7.  Duration of favorable wind, waves and tides.

8.  Type of sand or other material making up the beach and how it is packed.

9.  Beach saturation and pore pressures.

10.  Slope of the beach.

I also suspect that the wave periods may also have an effect.


The last few days have seen small surf, southeast wind.  There is no real changed expected very soon.  The tides are not as big now.

Happy hunting,
