Other names that Trisha is associated with are Fanta, Scooty Pep and Cadbury’s Perk.Trisha Krishnan got her first break in movies with a small part in a Tamil movie Jodi . However it was Priyadarshan’s Laysa Laysa that got her noticed. Maunam Pesiyadhe in which she starred with Surya won her the Filmfare Best Female Debut Award (Tamil). It was a high grosser at the box office. She has acted with some of the most successful actors in the South like Madhavan, Prabhas, Surya, Siddharth, Dhanush, Arya and Vikram.She delivered several hits with Saamy , Ghilli , Varsham , Aayitha Ezhuthu and Nuvvostanante Nenoddantan . Both Varsham and Nuvvostanante Nenoddantan fetched her many awards including the Filmfare Best Actress Award (Telugu). Some of her movies failed to do well like Ji , Aathi , Pournami and Sainikudu . But she continued to hold her place as one of the top actresses with movies like Something Something Unnakum Ennakum , Kireedeem and Krishna . Most of Trisha’s releases are Tamil like Sarvam, Vinnaithaandi Varuvaaya, Aadu Kalam and Chennayil Oru Mazhaikalam.

DIAMOND: THE PRICIOUS STONE IN THE WORLD
This article is about the mineral. For the gemstone, see Diamond (gemstone) For other uses, including the shape , see Diamond (disambiguation).In mineralogy, diamond (from the ancient Greek αδάμας – adámas "unbreakable") is an allotrope of carbon, where the carbon atoms are arranged in a variation of the face-centered cubic crystal structure called a diamond lattice. Diamond is less stable than graphite, but the conversion rate from diamond to graphite is negligible at ambient conditions. Diamond is renowned as a material with superlative physical qualities, most of which originate from the strong covalent bonding between its atoms. In particular, diamond has the highest hardness and thermal conductivity of any bulk material. Those properties determine the major industrial application of diamond in cutting and polishing tools.Diamond has remarkable optical characteristics. Because of its extremely rigid lattice, it can be contaminated by very few types of impurities, such as boron and nitrogen. Combined with wide transparency, this results in the clear, colorless appearance of most natural diamonds. Small amounts of defects or impurities (about one per million of lattice atoms) color diamond blue (boron), yellow (nitrogen), brown (lattice defects), green, purple, pink, orange or red. Diamond also has relatively high optical dispersion, that is ability to disperse light of different colors, which results in its characteristic luster. Excellent optical and mechanical properties, combined with efficient marketing, make diamond the most popular gemstone.Most natural diamonds are formed at high-pressure high-temperature conditions existing at depths of 140 to 190 kilometers (87 to 120 mi) in the Earth mantle. Carbon-containing minerals provide the carbon source, and the growth occurs over periods from 1 billion to 3.3 billion years (25% to 75% of the age of the Earth). Diamonds are brought close to the Earth surface through deep volcanic eruptions by a magma, which cools into igneous rocks known as kimberlites and lamproites. Diamonds can also be produced synthetically in a high-pressure high-temperature process which approximately simulates the conditions in the Earth mantle. An alternative, and completely different growth technique is chemical vapor deposition (CVD). Several non-diamond materials, which include cubic zirconia and silicon carbide and are often called diamond simulants, resemble diamond in appearance and many properties. Special gemological techniques have been specially developed to distinguish natural and synthetic diamonds and diamond simulants.
