Natural Blue Topaz - Brilliant Pear
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
Spinel - Iron Cross gemstone

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.

Y.A.G. - 'Desoppo Bars'
YAG - Desoppo Bars Gemstone

Design by Marco Voltolini, 25 facets.

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.

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.

Lithium Tantalate - Brilliant Rectangular Cut V.Rare
Lithium Tantalate! Brilliant Rectangular Cut

Lithium Tantalate is a labgrown ceramic occasionally used in specialised semiconductor sensors. Very rare this piece is a legacy of the soviet defence industry. With a high refractive index (2.2) similar to that of diamond and crazy high dispersion - three times diamond's this is a very attractive material. With such high dispersion one sees rainbows in direct light. Super - If you can get any!

To the best of my knowledge this is the only Tantalate gemstone presently for sale worldwide.

The stone is cut with a brilliant pavilion (bottom) and a step cut crown.

Natural Brazilian Amethyst - large custom Flower Cut

Rather a large stone at 14.7mm diameter. The surface is very well polished, marks you can see are due to spiral inclusions and a veil within the stone. Personally I find these add character. If one wants a perfect stone then - man-made is the way to go.

'Gram Emerald', Design by Jeff Graham, 45 facets.

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.
