|A collection of ancient Roman, Greek, Viking and medieval rings, once owned by a Leicester gas engineer, are expected to raise between £80,000 and £100,000 at auction. |
The rings, described by an antiquities expert as among the best he has seen outside a museum, are coming up for auction later this month. The ancient haul of 54 rings was gathered in the late 1950s and early 1960s. The rings are between 2,200 and 1,800 years old and many are exceptional and extremely rare.

|The commercial realities of gem-cutting means there is little emphasis placed on high-quality gemstone faceting. To obtain as great a carat yield as possible from rough, various methods are used to squeeze cuts out of the gemstone while bypassing visible inclusions at the expense of symmetry. Since each carat is real money, gem-cutters and sellers shut their eyes to optical defects.|
|High-quality gem cutting ensures the perfect flatness of facet surfaces that increase a gemstone’s ‘fire’ due to virtual prisms formed by the facets. Fire produces sparkle – light patches of colour different from the main colour of a gemstone – and is one of the most considerable advantages of a faceted gemstone.|
Nowadays the quality of faceting is not shown in gemstone certificates. Gemstone laboratories have developed systems of grading cuts, but they prefer not to draw attention to it as they don’t want to reduce the appeal of the gemstone to customers.

|A $30 million pink diamond is being held “hostage” by one of its co-owners, a Manhattan Supreme Court lawsuit alleges. The “Juliet Pink” – described as “among the largest and most valuable colored diamonds currently on the market” – was bought by L.J. West Diamonds in 2011. The company sold a 15% stake in the Juliet to Global Diamond Group Ltd., and another 10% to a diamond dealer. L.J. West agreed to give Global Diamond Group temporary “possession” of the stone May 22, but Global Diamond Group still hasn’t returned the gem – violating the ownership agreement, the suit alleges.|
The 30.03-carat Juliet Pink Diamond is a Fancy Intense Pink oval diamond, with a VVS2 clarity grading. It was cut from a 90-carat rough from South Africa.

|People living near the active Kilauea volcano in Hawaii have reported finding green crystals near lava flows.||The green comes from olivine, a mineral common in certain volcanic rocks.|
|Amid the lava spilling from the volcano’s fissures, tiny, glittering green gems are appearing — at times even raining from the sky. There’s nothing precious about this olivine. The same tiny gems are embedded in the rocks and asphalt all over Hawaii. The rocks erode into fine sand, creating green beaches like Mahana Beach on Hawaii’s Papakolea coast.|
