lahsuniya vibhinn rangon men paya jata hai- hara, halka hara, pila tatha bhura. yah atyant kathor evan tikau ratn hai islie iska abhushnon men bhi upyog kiya jata hai. yadi lahsuniya ko kaibokaen ke rup men kata jae to iske upar parne vala prakash ek lanbi rekha ke rup men dikhai deta hai. yah rekha kaibokaen ki upri satah par dikhai deti hai. isi rekha ke karan ise kaits aikhte hain jo billi ki ankh ki tarah dikhti hai. yah rekha (ankh) hamen lahsuniya ke andar bahut hi mahin samanantar suiyon se prashoshit hone vale prakash ke karan dikhti hai. yah ankh hamen samanantar suiyon se 900 vali disha men samlanb dikhti hai.
ankh jitni gahri evan sundar hogi utna hi lahsuniya mahanga hoga. lahsuniya mukhyatah shri lanka, brajil tatha chin men paya jata hai. kai prakritik ratn aise hain jinhen lahsuniya kah kar becha jata hai. kyonki ye dikhne men ek saman hote hain tatha inki kimat lahsuniya ke mukable kafi kam hoti hai islie bajar men inhen bhi lahsuniya bata kar unche damon par becha jata hai. vaise to lahsuniya ki tarah dikhne vale kai ratn hain parantu bajar men mukhyatah kvatarj kaits ai, silimenait kaits ai, yustetait kaits ai, glas kaits ai, taermalin kaits ai, spainal kaits ai, sinthetik kraisoberil kaits ai upalabdh hain.
inmen se kuch ratnon men kuch chijon ko ankhon se dekhakar ham yah andaja laga sakte hain ki vah kaun sa ratn hai jaise ki ankh ka rang parantu nishchit taur par inki ek ratn visheshagya, ratn prayogshala men ratn parikshan yantron dvara hi pahchan kar sakta hai. ankh ka rang: jab bat lahsuniya evan uski tarah dikhne vale ratnon men antar karne ki ho to uski ankh ka rang dekhakar yah anuman laga sakte hain ki vah lahsuniya hai ya nahin. jyadatar lahsuniya ki ankh ke rang men halka sa nilapan hota hai. vahin bajar men lahsuniya kahakar milne vali kvatarj kaits ai ki ankh ka rang safed hota hai.
yah lahsuniya ki ankh ke mukable thori chairi bhi hoti hai. yustetait evan glas kaits ai ki ankh ka rang jyadatar usi rang ka hota hai jis rang ke ve khud hote hain jaise ki hare glas kaits ai men ankh ka rang hara hoga. glas kaits ai ko glas ki sukshmadarshi mahin suiyon ko jorakar banaya jata hai islie yadi ham glas kaits ai ko ankh ki 900 vali disha men kisi sukshmadarshi se dekhen to vah hamen chote-chote binduon ya madhumakkhi ke chatte ke saman dikhai deta hai.
ise ham angreji men bhvadmlbvaui miimabaj kahte hain. ankh ke rang ko dekhna keval ek praranbhik lakshan hain. yah sunishchit kar lena ki agar ankh ke rang men halka sa nilapan dikhai de raha hai to vah lahsuniya hi hoga, galat hai. iski nishchit pahchan ratn prayogshala men hi ho sakti hai. kuch yantron ke nam tatha unke parinam, jisse asli aur nakli lahsuniya ko pahchana ja sakta hai, nimnalikhit hain.
