America)– Bangkok campus

Starting gemstone business

• Problems– No sufficient funds– No contacts– No practical expertise on gemstone pricing

• Solution– www-site for gemstone brokering services

The Big Problem

• Gemstone price is based on several individual quality factors

• Delivering these quality factors through electroning channels is… The Big Problem

• Tweezers• Proper lighting• Neutral background tray• (Comparison stones)

• Bright Field loupe• Dark field loupe• Gemology microscope

• Full laboratory equipments

Procedure

•Identity- Refractometer•Weight- Scale•HxWxD-Caliper

•Usually done by the seller

•Color- slightly rocking between the tweezers•Cut - slightly rocking between the tweezers, “on the move”- shape, symmetry and polish from static positions•Clarity- Colored stones

• Separation synthetic from natural gemstones- Identification of “birth marks”, i.e. inclusions•Detecting gem treatments-Identification of altered “birth marks”, inclusions- Identification of inclusions created by gem treatments•Clarity- Diamonds

Provided by a gemological laboratory, e.g.

• American Gem Society• Asian Institute of Gemological Science• Gemological Institute of America• Swiss Gemological Institute

Conclusion

• Gemstones have to be assessed on site in person in order to evaluate them fully– Requires Training and expertise

• Exception: Round Brilliant diamonds can be purchased without seeing the product based on a Gemology Report

Gemstone trade centers

The problem

• Sufficient and diverse gemstone supply is available only at certain trade centers over the globe

• Gemstones need to be assessed on site in person for a complete evaluationRequires time and money consuming trips on sites

and browsing numerous wholesalers• Exception: Round Brilliant Diamond

But what about current gemstone www-sites?

• http://www.gemselect.com/sapphire/sapphire-368934.php

• Based on photographs or simple videos– Cannot deliver sufficient visual information for

complete evaluation– Serious gemstone dealers are not attracated to

them

The Solution

• New photography technique provides a remote gemstone assessment with the same functionality and accuracy as with on site– full 3D view and motion control by a mouse– Zoom-in up to 10 times magnification– Bright field and dark field views– Controlled lighting– Plus more: measuring grid, light adjustment, color

samples and full depth of field

The imaging solution

1. Gemstone is photographed with macro lens in four degree-incremento 4050 separate camera angles

2. From each camera angle several photographs are takeno ~10 000 photographs totally

3. Photographs taken from the same imaging angle are combined using special softwareo High Dynamic Range (HDR)

imageo Utmostly sharpo Better color reproduction

Post processing

• Combined photographs are post processed in two ways:1. The subject is centered

o This eliminates a wobbling effect in a final video or 3D-applet

2. A shadow is added for the subjecto This creates three dimensional experience in the final

video or 3D-applet

• Both processes are done automatically by an external software

Final video and 3D applet

• Photographs are “fed” to video processing in predefined order– Like creating a movie from still photographs

• 3D applet on a user computer requests photographs from the server in a stream-like manner as the object (gemstone) is being handled using the computer mouse– i.e. turning, tilting, rocking, rotating, zooming in/out,

switching the background between dark field and bright field

Why Innofun?

• Idea from Digipolis (Jukka Auraneva) which provides services for start-up businesses

• This type of concept has many motion related aspects video is practically the only media for presenting the concept

Video production

• Straightforwarding– Startp-up meetings

• information exhange (gemstone and evaluation 101, material)

– 1. script• wants vs. no-can-dos

– 1. version• Test audience

– 2. script– Final version

• Test audience

• Feedback via e-mail– Not the best practise– Face-to-face meeting, video or phone conference better

Putting the video to work

• Investors• Subcontractors• Partners• Customers

Benefits

• Visuality– Motion, motion, motion

• Time saving– 3 minute video vs. 10 minute power point

presentation• Some motion related aspects nearly

impossible to present using static pictures or text
