|
'Spellbound Square', design by Jeff Rhonemus, 53 facets The stone has a slightly 'milky' tone due to a small internal veil on one side which reflects around. To the naked eye, rather than a photograph I see a pale, slightly smokey amethyst. A large stone suitable for a centrepiece.

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. 50% of sale price via this site will be donated to the British charity - World Jewish Relief. No retouching, colour modification nor dust spot removal. |

Y.A.G. - 'Desoppo Bars' | |
---|---|
![]() |
|
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. |

Natural Blue Topaz - Brilliant Pear | |
---|---|
![]() |
|
Design by Jeff Graham -vid Some slight veil in one corner though not really visible to the naked eye. The Brilliant Pear is designed to cut like a standard round brilliant and look like a pear. The light return is excellent, much better than any traditional pear I've ever seen. Unlike many pear designs, this one employs a centred culet. The pavilion is basically a split mains variation of the SRB with 3 elongated sets of facets, and the crown is also a modification of the SRB pattern. This produces a pleasingly shaped stone with the added attraction that this design can be mounted in standard 4-prong findings and settings designed for round stones. No retouching, colour modification nor dust spot removal. |

Zircon Spinel - Iron Cross | |

Brilliant cut square with frosted facets showing an Iron Cross - vid Design by Ian Robinson, 41 facets. 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. 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. No retouching, colour modification nor dust spot removal. |
