A match made in heaven

Look what ascended from the heavenly skies into the Garden of Adin this week: an angel statuette wearing this 18K yellow gold antique Georgian cross necklace! Even though this chain, cross, and its slider, both adorned with table-cut diamonds, date back to around 1730, they are still in immaculate condition: a true testimony of wonder.
Where will this angel make its next annunciation of a heaven-made match for this one-of-a-kind necklace?
