Mr. Ravi K Lashkery from Gemorex was very helpful at a recent meeting. I was attending the JA winter show and his booth had massive smooth emerald necklaces and a lot of unique cut stones and brioletts. He really was very knowledgeable and innovative. you can visit his web site to get an idea of the quality of his merchandise.
They also specialize is custom cut semi precious stones he showed me a few pieces they where working on for another client and I bought a few rose cut citrine, topaz and ruby as well as flat cut stones that are similar in style to the flat cut diamonds.
