  • REFRACTIVE INDEX


    is a measure of how light is refracted in a substance (like a gemstone).
    Diamonds for instance have a high index and refract light very quickly, hence the glitter they give off.

    Glass beads have variable levels of refraction.
    Lead in the glass will dramatically raise the index of refraction.
    In doubly-refractive stones, the light is split into two light rays when it enters the stone, and the rays travel in different paths - so these stones have more than one refractive index.

    are highly reflective, artificial gems made from either glass or rock crystal often with facets that sparkle in imitation of a diamond.

    The best rhinestones today are made of highly reflective leaded glass which is faceted and polished and are usually foil backed to improve the reflective quality.

    The name comes from the Rhine river, which was the source of quartz crystals that were originally used in making rhinestones.

    Because rhinestones could be made to imitate diamonds, the name rhinestone was applied to artificial gems made from paste, glass, or gem quartz and as a result often carries a connotation of showbiz glitz.

    Rosary can be made very simple or highly jewelled and ornamented.
    Rosary is derived from the Latin word, "rosarium", or rose garden.

    For Christians the red rose symbolizes the blood of Christ and the white rose the purity of the Virgin Mary.

    Among the Christian today, a full rosary consisting of 150 beads is called a chaplet or Psalter.

    This number corresponds to the number of Psalms.

    Fifteen larger beads divide the whole into decades or groups of ten. This emulates the original finger counting method for tracking prayer.

    The small decade or Ave beads are used to say ‘Hail Mary" prayers. While the large separator or paternoster beads are utilized in the "Our Father " and Gloria" prayers.

    Each decade represents a subject or mystery in the life of Jesus and Mary.

  • RUDRAKSHA BEADS





    are beads made of the seeds of the Rudraksha fruit obtained from rudraksha trees (ELAEOCARPUS GANITRUS ROXB.) mostly found in Java, Sumatra, Borneo, Bali, Timor, Iran, and Nepal.
    Rudraksha beads are classified on the basis of the number of "mukhis" - the clefts and furrows - they have on the surface. Most beads have something in between 1 to 15 mukhis.

    Among some Vedic astrologers it is believed that rudrakshas with different number of mukhis please different planets.
    Therefore, each bead has a different effect on a person, depending on the number of mukhis it has.

    The word 'Rudraksha' comes from the Sanskrit words, 'Rudra' ( one of the names for Lord Shiva) and 'Aksha' (teardrop).

    Mythological tales have it that the rudraksha plant was born out of Lord Shiva's tear drops. Ancient Vedic scriptures mention the wonderful powers of the rudraksha.

    For thousands of years they have been worn by sages and yogis of India and the Himalayas.

    Necklaces made of rudraksha are supposed to have profound astrological and health benefits.

    According to the ayurvedic healers, wearing rudraksha can have a positive effect on the heart and nerves; relieve from stress and depression.

    It is also known for its anti ageing effect, and electromagnetic and inductive properties.
