Large Star of David in Lithium Niobate

'Star of David #3', adapted from a design by Fred van Sant, 61 facets

My latest Star of David - a popular design for me. This is cut in the rather rare Lithium Niobate and is most probably the only one presently available worldwide :-). Rather pleased, this rough video does not do it justice - in sunlight this material explodes into a riot of colour.

Not easy to do, getting the frosting this even is tricky whilst the Niobate was an absolute sod to polish. I nearly gave up - unfortunately giving up is something I find difficult. Probably took about 40 hours all told.

Y.A.G. - 'Desoppo Bars'

YAG - Desoppo Bars Gemstone

Design by Marco Voltolini, 25 facets.

An interesting variant on the ‘opposed bars’ concept. Usually opposed bar designs have the bars inverted (orthogonal) with respect to this design. The upshot being that rather than seeing long bars one sees squares. As the stone is moved square flashes occur.

Yttrium Aluminum Garnet, as known as alexite, amamite, circolite, dia-bud, diamite, diamogem, diamonair, diamone, diamonique, diamonite, diamonte, di'yag, geminair, gemonair, kimberly, Linde simulated diamond, nier-gem, regalair, replique, somerset, triamond, YAIG, and yttrium garnet. This was widely used as a diamond simulant before the development of lab-grown cubic zirconium. It has a high moh hardness of 8.5, higher refractive index than sapphire (more sparkly) and a high dispersion. Widely used in the laser industry it is a rare gemstone material.

Zircon Spinel - Iron Cross

Spinel - Iron Cross gemstone

Design by Ian Robinson, 41 facets.

Brilliant cut square with frosted facets showing an Iron Cross - video

Having cut a number of cross designs I was looking for one that was simple and bold where the design could be clearly seen without magnification. This seems to work well and has attracted a lot of interest. Cut in Swiss lab-grown Spinel

The Iron Cross has been a German military award from 1877 to the present and its design may be traced back to the cross pattée of the 11th century Teutonic Knights of Jerusalem and earlier.

Natural Tourmaline - 'Emerald Cut'

Cut in dark moss green natural tourmaline.

This is not the highest quality tourmaline hence the low price. However the cut is certainly to at least my usual standard. The stone is eye clean and large enough to form the centrepiece of a pendant.
