Certificated Diamonds

Most diamonds are graded by the retailer from experience and via merchant agreements. We insist that our merchants supply at least the minimum standard that we state and then we check every stone ourselves. We warrant the grading in writing on our valuations, each of which is personally signed by a director of this company. We also offer this collection of 232 pieces set with independently certificated stones. Each is supplied with its own unique certifiicate specifying its quality.

Thermal properties

Thermal properties

One of many remarkable properties of diamond is its unsurpassed thermal conductivity. With a value of 2000 W/mK it exceeds that of copper by a factor of five. In contrast to metals, where heat is conducted by electrons, lattice vibrations are responsible for diamond's high thermal conductivity.

For thermal management applications, the outstanding thermal conductivity and diffusivity of diamond is an essential. Nowadays CVD diamond is used as submounts for high-power integrated circuits and laser diodes.


Thermal conductivity @300K > 1800 W/mK
Thermal Expansion Coefficient
@300K 1.0×10-6 K-1
Spectral Specific Heat 5.02 J/kgK

Necklaces & Pendants

A necklace is an article of clothing or jewelry; which is worn around the neck. Necklaces are frequently formed from a metal chain; often attached to a locket or pendant. Necklaces can also be manufactured with cloth, and they sometimes contain rocks (particularly gems), wood, and/or shells. When worn high on the neck it is referred to as a choker. Many Christians wear a cross or crucifix which differs in shape, size, material and color. Others wear the cross merely out of decoration and may not be Christian. Historically women initially wore necklaces to draw attention to the cleavage region.

Simulants

A diamond simulant is defined as a non-diamond material that is used to simulate the appearance of a diamond. Diamond-simulant gems are often referred to as diamante. The most familiar diamond simulant to most consumers is cubic zirconia. The popular gemstone moissanite (silicon carbide) is often treated as a diamond simulant, although it is a gemstone in its own right. While moissanite does look similar to diamond, its main disadvantage as a diamond simulant is that cubic zirconia is far cheaper and arguably equally convincing. Both cubic zirconia and moissanite are produced synthetically.[74]
