List of semiconductor materials - Wikipedia
A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors typically form in periodic table groups 13-15 (old groups III-V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).

Semiconductor materials. Solid-state materials are commonly grouped into three classes: insulators, semiconductors, and conductors. (At low temperatures some conductors, semiconductors, and insulators may become superconductors.)The figure shows the conductivities σ (and the corresponding resistivities ρ = 1/σ) that are associated with some important materials in each of the three classes.
Is Diamond a Conductor? - ThoughtCo
The thermal conductivity of natural diamond is around 22 W/(cm·K), which makes the diamond five times better at conducting heat than copper. The high thermal conductivity may be used to distinguish diamond from cubic zirconia and glass. Moissanite, a crystalline form of silicon carbide that resembles diamond, has a comparable thermal conductivity.

Material properties of diamond - Wikipedia
Diamond is the allotrope of carbon in which the carbon atoms are arranged in the specific type of cubic lattice called diamond cubic. Diamond is an optically isotropic crystal that is transparent to opaque. Diamond is the hardest naturally occurring material known. Yet, due to important structural weaknesses, diamond's toughness is only fair to good.

Antique Paste Jewelry | Collectors Weekly
In the aristocratic classes of 17th century Europe, particularly the taste-making rococo Parisians, fine jewelry made of precious gemstones like diamonds and emeralds was flaunted and coveted. These stones were treasured for their beauty as much as their relative rarity—it was this rarity that prompted jewellers to seek out an equally beautiful, but less expensive, alternative material for ...
