Design N^o7 - Apostate A - vid

Gorgeous cobalt blue lab grown spinel in my Apostate cut. Brilliant cut pavilion and a high crown with 8 narrow frosted parallel-sided facets in a star shape. Quite a large stone which would make an impressive centrepiece or single setting. This should be easy to set in a round setting.

Tears of Elune, design by Arya Akhavan. Cut in light pink sapphire -vid.

Nice: shard like narrow pear shape.

Somewhat time consuming and fiddly to cut taking me about twice as long as similar pear designs.

Radiant Ice - based on radiant Emerald by Grossbard & Steele. Cut in Leuco (pure-clear) lab sapphire -vid.

Tricky to photograph.

Pyroclastic Flow by Arya Akhavan - vid

Natural deep red garnet in Arya's Pyroclastic Flow cut.

This design really work with the deep red of garnet. Tricky to photograph, in direct light one see sudden brilliant blood red flashes as the stone is moved. Up close it resembles dully glowing lava (at least to my eyes)

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.

Standard Round Brilliant - 'Stacked Mains - design by Long & Steele

Just a comparison of 2 pairs of sapphires cut in hot pink and lilac-pink sapphire. They are very bright and sparkly, in part due to the quality of polish on the pavilion - the bottom of the stone.

Standard Round Brilliant - 'Stacked Mains - design by Long & Steele

This is a matched pair of precision cut sapphires each of 2.90ct. 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.

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 11^th century Teutonic Knights of Jerusalem and earlier.

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.

Hanami (花見, "flower viewing") is the Japanese traditional custom of enjoying the transient beauty of flowers Another interesting design by Marco Voltolini. 'Hanami' is modelled on a cherry blossom. A set of tiers is left frosted with the 'petals' polished.

'Yup, so really I just wanted a crown that looked like the line angle structure of hexanitrobenzene'.

A rather nice design from Arya Akhavan with the crown formed from 7 hexagons. Cut in Rose de France - natural light coloured amethyst.

Classic Square Brilliant Cut

Came out rather nice Strictly approx 1/3^rd of stone is amethyst with 2/3^rds being citrine. Under normal lighting the internal reflections tend to make the effect more symmetrical.

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.

'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.

This was cut in lemon quartz, likely natural (not irradiated) as from 1974 stock. Two bubbles are carved into the bottom giving rise to interesting reflections.

Cut in Rose De France (light Amethyst). Marking are internal to the stone due to reflections from a small veil - I think this adds interest :-)

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

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.

The video on youtube may give a better impression than the photo above
