Type of jewel: Vintage antique Art Deco gold locket set with diamonds and rubies Condition: very good Style: Vintage 1920's Art Deco Style characteristics: Abstract motives and geometrical forms are quite typical for the Art Deco period. Era: ca. 1920 Material: 18K yellow gold (touchstone tested) Diamond(s): Thirteen rose cut. We do not have the weight of these diamonds which is normal in our trade when it comes to rose cuts. All diamonds in our vintage and antique jewellery are verified by the IJGC-lab to confirm whether they are natural or lab-grown. We do not offer any pieces with lab-grown diamonds. Thus, we assure that all diamonds in this jewel are 100% natural. Precious stone(s): Twenty rubies (lab produced, also called Verneuil ruby). The fact that these are lab produced stones has no negative influence on the value of this jewel. Both natural and lab produced stones were used in this era, rather for their effect than for their intrensic value.

Such pieces frequently bear marks of this tender care. Furthermore, we present our antique and vintage jewellery in its authentic state, refraining from removing scratches or applying rhodium plating to white gold items. Our priority is to preserve the genuine allure and history of each piece. However, as the new owner, you have the option to take it to a local goldsmith for a cosmetic refresh, should you choose.
