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 Black Spinel - Lucifer Cut
Lucifer Black Spinel

Lucifer - design by Jack Rowland, cut in Indian black spinel

I do like spinel feeling that the surface lustre is superior to sapphire. Black spinel has to be polished with great care as the smallest scratch is apparent.

Was there any point cutting the pavilion (bottom) No - apart from a sense of completeness. In the video under bright light and high magnification it become apparent that the stone is actually a very deep red - to the naked eye appearing jet black. There is a very faint mark on the top facet - not an error but an internal fault in the stone. This is not visible to the naked eye, only under high magnification.

This was a bugger to photograph, a better view is the video below.

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.

'Chrysanthemum', design by Quincy D Howell, 81 facets

This is a matched pair of fairly large (10mm) precision cut sapphires each of 5.3ct. Would look nice in large drop earrings. Being essentially round (strictly 16 sided) they should be easy to set. They are very bright and sparkly, in part due to the quality of polish on the pavilion - the bottom of the stone.

Rutilated Quartz - 'Corner Cut Triangle'
rutile quartz - corner cut triangle

design by Fred van Sant, 37 facets

I feel there is too much emphasis placed on clarity and lack of inclusions. Rutilated quartz is a lovely material with fine needle-like stands of golden rutile (titanium dioxide) making for a very interesting stone. Faceted rutile quartzes are regular award winners in major faceting competitions. The rutile strands can however make polishing the surface a bugger.

This was triksy to photograph - see the video for a better impression.

The final high polish is achieved with 0.3 micron chromium dioxide polish on a darkside lap for extra flatness and crisper facet edges.

Hanami (花見, "flower viewing") is the Japanese traditional custom of enjoying the transient beauty of flowers 'Hanami', modelled on a cherry blossom is becoming one of my favourite cuts. A set of tiers is left frosted with the 'petals' polished.

A delicate subtle cut! - apologies for the poor photo - the video gives a better view.

AS for the colour. Well I thought I was ordered a kunzite colour - a light lilac. It looked lilac - however on cutting I found it to be more a shocking electric pink. I like this and will definitely get more if it is available.

The final high polish is achieved with 0.25 micron diamond polish on a ceramic lap for extra flatness and crisper facet edges. This followed a deep pre-polish at 3 micron on a Batt lap. This stone took me about 9 hours to cut.

Square Cushion

Classic square baguette design, this is a rather classic look, very bright showing off the colour well. The cutting was freehand i.e. not from a standard design.

An artisan jeweller should have no problem making a setting at a reasonable price creating a remarkable unique piece at a fraction of the cost of the high-street.

The final high polish is achieved with 0.3 micron Cerium Oxide polish on a ‘Darkside lap’ for extra flatness and crisper facet edges, this following a deep pre-polish at 3 micron on a Batt lap. This stone took me about 10 hours to cut.

An interesting variant on the ‘square barion’ concept with the table rotated by 45 degrees. This has been used in cutting competitions in the UK and US. The pavilion is essentially brilliant cut giving a very bright sparkly appearance with plenty of dispersion. The stone is a deeper blue than appears in the photograph.

An artisan jeweller should have no problem making a setting at a reasonable price creating a remarkable unique piece at a fraction of the cost of the high-street.

This stone are much better polished than you are likely to find on the high street giving a much brighter stone.

The stone is cut with a brilliant pavilion (bottom). Ruby is a dark stone, however this size and cut gives blood red flashes in direct light. Gemstone photography is awkward - the stone is a deeper blood red than the images show - rather gothic really.
