Color described in the accompanying report as green. Geographic origin Colombia.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eREPORT:\u003c\/strong\u003e Accompanied by an SGL Gemstone Identification and Origin Report, report number 190509O-SB, dated May 28, 2019, signed by Bear Williams, FGA, CG and Cara Williams, FGA. The report identifies the stone as beryl, variety emerald, and states the opinion that the country of origin is Colombia. The report notes evidence of clarity enhancement.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTREATMENT DISCLOSURE:\u003c\/strong\u003e This emerald has been clarity enhanced. The practice, commonly referred to as oiling, involves filling surface reaching fissures with a colorless substance to reduce their visibility. It is common and accepted throughout the gem trade and applies to the overwhelming majority of emeralds offered at every level of the market. The treatment is impermanent, may diminish over time, and can be renewed by a qualified gemologist.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eACCENT STONES:\u003c\/strong\u003e Seven graduating marquise cut and six straight cut baguette natural, earth mined diamonds, total weight approximately 1.00 carat, graded approximately G to H in color and VS in clarity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCONDITION:\u003c\/strong\u003e Examined under magnification. All stones present and secure at the time of examination. Mounting sound with no evidence of prior repair.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eREMARKS:\u003c\/strong\u003e Colombian origin is the benchmark for emerald and remains the standard against which material from every other deposit is measured, which is what makes a documented origin opinion worth having on a stone of this size. The mounting is characteristic of the 1940s, when platinum work returned after wartime restriction and asymmetric diamond sprays came into fashion. The graduation of the marquise stones and the run of baguettes framing them is careful bench work rather than a stock head.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCARE:\u003c\/strong\u003e Because clarity enhancement in emerald is impermanent, clean with warm water, mild soap, and a soft brush only. Keep away from ultrasonic machines, steam, solvents, acetone, and harsh detergents.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eDiamond weights and grades stated are approximate and determined while the stones are mounted.
