| Pink Sapphire! Emergent Phenomenon | |
|---|---|
|
|
|
Emergent Phenomenon - design by Arya Akhavan When I first saw this I thought - "hmm OK, standard looking triangle". Upon cutting I thought "Wow". This is one of the brightest designs I have ever seen. Arya is an accomplished designer and the myriad internal reflections make this one of my new favourite cuts. No retouching or colour modification (or dust spot removal!) |

| Ruby - Lucifer Cut | |
|---|---|
|
|
|
Lucifer - design by Jack Rowland The devil you say! Lucifer is also known as the light bearer. I don't think I could have come up with a better name for this fiery gem. This is a super nice triangle. It is bright, has lots of action. Also very unusual with it's asymmetric crown - the twisted triangle concept. No retouching or colour modification (or dust spot removal!) |

| 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! The stone is cut with a brilliant pavilion (bottom) and a step cut crown. No retouching or colour modification (or dust spot removal!) |

| Ruby - Sweetheart Cut | |
|---|---|
|
|
|
Sweetheart is a classic heart shaped cut by the noted designer - the late Jeff Graham. This would look nice as a single stone in a pendant or large ring. 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. No retouching or colour modification (or dust spot removal!) |

| Amethyst - Daffodil Cut | |
|---|---|
|
|
|
Another slightly unorthodox cut. The design is by Marco Voltolini - unusual in being hexagonal - though this does make it easier to set. The lowest tier of facets on the crown (top) are frosted to enhance the petal effect. Photo taken in natural light - no retouching or colour modification (or dust spot removal!) |

| Amethyst - Cube Illusion Cut | |
|---|---|
|
|
|
An unusual and rather difficult cut. Reminds me of an Escher drawing, when moved the central cube appears and disappears. This particular cut is surprisingly tricky, I went through a number of stones before I got it right. It took so long that I am unlikely to do another for some time. Photo taken in natural light - no retouching or colour modification (or dust spot removal!) |

| Pink Sapphire - Rand's Cut Corner Rectangle | |
|---|---|

Design by Dan Clayton for the U.S. Facet Cutters Guild competition in 2010. This is one of my favourite cuts and straightforward to set as a pendant or ring. Photo taken in natural light - no retouching or colour modification (or dust spot removal!) |

| Padparadscha Sapphire - Alien Outpost Cut | |
|---|---|
|
|
|
The cut is 'Alien Outpost' by Greg Glenn - a classic gemstone designer. 49 facets optimized for sapphire. This stone was very slowly cut to minimise sub-surface damage, mostly on 3000 grit, pre-polished on 8000 grit and finished on 100,000 grit using a ceramic lap for maximum sparkle and flatness. A very bright and relatively large stone I feel this would make a stunning pendant even in a minimalist setting. |

| Pink Sapphire - Sweetheart Cut | |
|---|---|
|
|
|
Sweetheart is a classic heart shaped cut by the noted designer - the late Jeff Graham. Looks stunning in this very simple silver bar setting which really shows the stone off. So little metal touches the stone that it really flashes in sunlight. |
